As in the car to make 220 volts. How to put a rosette into the car. Choose an inverter. Classification of inverters for power connected consumers and type connection to the on-board network

Modern living conditions require constant movements within the city, travel travel on long distances, traveling different countries World. Thanks to the personal car, any trip turns into a fascinating tour, during which you can enjoy the wonderful landscapes, to know new attractions. During the planned journey, a person should stay in touch all the time, and also be able to use the necessary set of electrical appliances for its needs and needs. Uninterrupted current supply and excellent work of any electrical technology will provide car inverterwhich is beneficial from the standard cigarette lighter used throughout.

What is an inverter and why it is needed.

The car inverter is a special device converting an output current from a car battery with a standard voltage of 12 V to an acceptable current for modern electrical appliances and digital devices. Classical output power is considered to be 110/220 W. Effective work and recharging of various power tools, pumps, video and audio equipment, laptops, tablets, phones, even microwaves and toasters taken on the road ensures that voltage in 220 units. Each car inverter has a built-in protection system that protects the device from overload, overheating and high voltage power. This allows the motorist to use one inverter for long years to connect the most diverse electronic technology.

Automotive inverters are attached to the battery, which is inside the car, using special clamps or terminals, which usually go to the kit together with the device. Also, some low-power models have the ability to connect directly into the cigarette lighter socket, however, such devices are suitable for long-term recharging mobile phone And no more. In this article, we will discover their attention on the classic 12-220 W inverters. In our store you can with both types of connections.

Some features of the choice of the device.
The choice of a high-quality car inverter can take some time from the motorist, since the car goods market is Pttit today and it is very difficult to figure out what exactly the inverter model will last for many years. First of all, during the choice of the automotive inverter, it is necessary to pay attention to its technical data reflected in the accompanying vehicle. The output current of the inverter most often forms a modified sinusoid, which will end up the reason for the failure of the entire electronic technology connected to the inverter. The first criterion for the quality of the inverter is the pure sine of the converted current. The price of a device that has a clean sine at the exit will be an order of magnitude higher than the cost of classic car inverters, however, due to the high efficiency of the current conversion, such a device will last much longer and retain all electrical appliances in working condition.

When buying a car inverter, it should be tested to the maximum output power. So, for example, a device with 12 V - 220 W characteristics at the highest load may produce voltage in just 196 watts. The power of the inverter should not exceed the power indicators of the automotive generator, but at the same time have a voltage twice as compared to the current consumption instrument used.
Before testing, the inverter must be turned off because when turned on car Engine There is a strong tension jump from the on-board network, as a result of which the included inverter can simply burn. During the check, the starting current indicators increase to determine the maximum voltage, which can proceed from the device. Especially such a check is recommended for those who are going to connect various electrical appliances to the car inverter.

It should also be considered the fact that the larger output voltage indicator is calculated by the car inverter, the more electricity it will "pump out" from the autosystems. In this case, to maintain the operation of the inverter, you will need to increase engine speeds (if before it was included at idle), which will lead to increased flow Fuel. Some devices can also use electricity located in a car battery, thereby faster discharge it. These aspects, perhaps, can be attributed to the disadvantages of almost all automotive inverters, since the principle of their work itself directly depends on the voltage, which is made by the automotive generator. The range in our online store includes a power model from 150 to 700 watts.

What else to pay attention to?
The high-quality inverter is equipped with protection against overloads, closures on the network, overheating, exceeding or reducing the input voltage. Built-in alert signal possible faults Or dropping the battery power will allow the car owner instantly eliminate the malfunction. In the event that the autogenerator will give the inverter less current, the battery of the machine will quickly sit even when the engine is turned on.

Many manufacturers of inverters focus on external design The device, while leaving the basic function of the device underdeveloped - the current conversion. As a result, it turns out that acquiring an inverter capable of recycling 12 in the battery in 220 W, a person cannot elementary to charge the phone or boil the teapot, since the maximum power does not match the specified. IMPORTANT when choosing an inverter to navigate not to the presentable appearance, and an internal filling that will ensure the effective use of all necessary devices.

To the choice of the car inverter you need to be consciously and understand, for what purposes it will need to be used. If you are thinking about universal device For the technique of any power, the models are suitable for more expensive, but at the same time more powerful. If your goal is to apply the inverter as a source for recharging digital devices, the most optimal option Shopping for you will be a car inverter with indicators of 150-300 W.

The number of electric I. electronic devicesThe need for a person occurs daily, is constantly growing. It is enough to remember the somewhat most common: razor, smartphone, laptop, camera.

Some of them have built-in low-power batteries and can be charged from a short voltage. For them, the manufacturer, as a rule, provides a charger operating on the car cigarette lighter connector. However, there are also those that can only work from the household network, as they consume a sufficiently large current when charging the battery. Such instruments refers, for example, most of the laptops.

In addition, many household appliances that may be needed on a long journey can only work from the household network with alternating stabilized voltage of 220 volts and a frequency of 50 hertz.

Inverter connected to the onboard network, in fact, makes it possible to have a regular household outlet in the car

The strict requirements for the power grid are due to the presence of electrical components, such as pumps or compressors that simply cannot work with electricity bad quality And quickly fail. Therefore, it requires a device that not only converts 12 volts to 220, but also gives out a current that corresponds to a number of parameters.

What is an inverter and what is it used for?

In the onboard network of the car flows a constant current having a voltage of 12 volts. The inverter connected to the onboard network is essentially makes it possible to have a regular household outlet in the machine, which can include household appliances and tools: computers, charges for phones, microwaves, refrigerators, etc.

Select the inverters should depend on what devices will be used with them.

There are practically no restrictions on the use of technology, but you need to always represent how much a device consumes to use the inverter with it, designed for such consumption, since in a low-power inverter, for example, the refrigerator cannot be turned on - it will simply burn fuses.

Classification of inverters for power connected consumers and type connection to the on-board network

Not only long and uninterrupted work, but also the safety of the automotive network depends on the proper selection of the inverter. Select inverters should depend on what devices will be used with them. Information about the middle and peak power consumption (peak consumption is the maximum power that the device is capable of consumeing, as a rule, equipped with an electric motor or another component requiring start-up) is contained in the user manual, in the "Basic" section specifications" In accordance with these parameters and the inverter should be selected.

If the user's manual says that the peak power is 500 watts with an average power of 300 watts, then you need to buy an inverter per 1 kW, with a margin. On the one hand, the device will be guaranteed to start and work, on the other, using the inverter, you will act as part of safety.

There are two main directions of the classification of inverters - at the total power of connected consumers (200 V, 1 kW and so on), and by type of connection - to the cigarette lighter connector using special power wires equipped with clamps. These two parameters are associated directly - inverters with a power of up to 200 watts are connected to the cigarette lighter, more powerful to the battery terminals. This division is due to the fact that the wires leading to the cigarette lighter socket are not designed for great consumption, and if you turn on a high power inverter into the outlet, it will begin to warm up, and if the fuse does not work on time, they can and melt.

How to install and use the inverter

To the use of low-power inverters, which are connected to the cigarette lighter of special requirements is not presented. The temperature range in which they can work - from -15 to +50 degrees in normal humidity conditions. Do not leave a working device under the right rays of the sun. It is also not recommended to hide it into boxes and under the seats, since the inverter is heated, and warm, to avoid disconnecting the device, should be removed from the body circulating in the cabin air.

In principle, all the same requirements also apply to more powerful inverters that are connected to the battery terminals. There are also specific important requirements: you can not turn on the ignition of the car and start the motor if the inverter is connected to the dismanded battery to which the car wiring terminals are connected.

In principle, the inverter is equipped with protection from most abnormal situations. For example, when the current drops at the inlet to a voltage of less than 11 volts on the inverter housing, the alarm lights up, and if the voltage drop becomes critical, the beep can be fed. Protection against overheating, as well as from short circuit.

What devices can be connected to the inverter and which restrictions exist

Most household appliances, especially electronic, undemanding to the "quality" of electrotock in the network and do not have peak load modes. However, audio equipment, for example, works well from household power grid and can work badly if you connect it to the inverter.

The case is here in one of the current parameters at the outlet of the inverter, which is called the sinusoid. Without going into technical details, we can say that this sinusoid is reference in the household power grid. However, the majority inverters available in the market can not produce a current with an ideal sinusoid. If this parameter is still comparable to the household network, the device will be very expensive. The current of most inverters has a modified sinusoid, which means that in the sound of the audio system columns, for example, may appear foreign Summas, so-called tip.

Do not like the modified sinusoid pumps of some types and a number of electrocomponents. However, the form of the overwhelming majority of instruments does not have the form of sinusoids. As a rule, in the instruction manual, all restrictions are described.

Thus, to choose a suitable inverter, you need to make simple calculations. You must calculate the total consumption of all the devices that you are going to include it. At the same time, if the electrical appliances have a peak load parameter, you need to buy an inverter, taking into account exactly this parameter. In addition, it is necessary to include a certain margin in the calculation, since the documented peak load, for example, the refrigerator at the time of the compressor starts, may differ from the claimed. In the case of the correct calculation of consumption, the device is guaranteed to "pull" everything that you turn on it.

It remains to say only about the time of work from the battery without recharging. It is best to do this on the example. A car inverter, designed for 2 kW, is able to feed the summer boiler with an exemplary consumption of 800 watts for approximately 2 hours from the battery with a capacity of 60 amps-hours, provided that the battery is in normal operating condition. After this time, you must have a replaceable additional battery under hand.

Summer - season of vacation, pokatushek at sea and in the forest, time of incredible stories and insane adventures. Already anticipating when the boss releases you to rest to jump into the favorite pelvis and go to explore the places where the person did not go?

Do not forget to get a rosette in the car to charge all your gadgets at least on the beach! Strange, but many do not know that in the car it is very easy to addAnd today we will talk about it.

In the work on this material, I was helped by a car master with golden hands Bogdan D., together thank you together, laid down all the nuances on the shelves.

Do you need a car inverter, what is it?

In modern cars, the mass of electrical devices running from the battery. They need a voltage of 12V, and all the electronics inside your pelvis is designed precisely under it. But you need 220 or so where to take it?

Imagine, want to go with your friends to nature, download to the shrimp in the pan, throw it all on the fire and celebrate any day of summer with a good European beer. You take from the house the most ordinary audio system and connect to the outlet right in the car. Great plan!

To realize the conceived, you need to buy a couple of kilo seafood, the box is unfiltered and car inverter.

This is such a device that will help convert the current in the machine electrical system as necessary and enable the ability to connect not only the home audio system, but even a TV or refrigerator.

Car inverter converts constant voltage in a wheelbarrow to variable - This is used at your home. This requires a built-in current generator. He creates a harmonious wave, which reworks your 12V in 220 or so.

In the normal inverter there are also protective mechanisms. They are needed that the device does not catch up when it is too much warm from high load. There are even models in which the active air-type cooling is provided.

And what inverters externally? Most often it is such small boxes that can be connected or to the cigarette lighter, or directly to the electrical system of the car.

They have several outlets to connect the most ordinary forks from household appliances, and on some - even a USB pair, and any mobile gadgets can be shovel.

In general, if you plan to go to search for adventures, you just need an inverter.

The expensive inverter differs from cheap and vice versa

I am sure you have already ran on online stores to look for a suitable inverter. When you understand that the price of these devices may differ in tens of times, come back to this article and learn more.

Be sure it's not just a brand name. No, in most cases, the functionality of the device is influenced by the cost - for example, its power.

The expert, whom I invited to support the information of the experience, proposes to share all the inverters in this plan into three categories.

Up to 300W. These are the weakest models that in most cases are connected to exactly through the cigarette lighter. There are options when such can be attached directly to the car's power grid, but it is meaningless - too much troubles.

Most often such taking to feed mobile devices And some laptops. But sometimes it's easier to just shove a car charging into the cigarette lighter.

300 - 1500W. Such car inverters are called standard or ordinary. They are powered only directly from the mains of the machine.

They can be used to connect a telly, any laptop and even microwaves.

More 1500W. These particularly powerful inverters are connected only to the electrical outlet, and they choose them mainly for complex work in the wilderness (for example, construction).

You can easily connect to this and drill, and the grinder, if it really needs.

Look, when you choose the inverter, focus so that it exceeds your power devices at least 20-30%. If you connect something too powerful, it burns and risks to burn the wiring in the wheelbarrow (at least in theory). And 100% for a long time Do not upload, risk spoil.

If the devices that you plan to connect to the inverter require a stable 220V, choose the most powerful one - more than 1500 W. 300W models are unlikely to give out more than 200V.

Each car inverter can operate in 3 modes:

  • Startup mode - On it the device quickly gives the maximum power to "start" something demanding. In this mode, it will not last long.
  • Normal mode - In such an inverter supports its usual power, how much you need.
  • Overload mode - Especially powerful mode. In such an inverter will work up to 30 minutes, in this case It gives up to 1.5 more declared power.

Engineer with experience will confirm that at maximum power, any device will not live long.

Here, the inverter in 95% of cases should be used as usual, and for this it does not need to connect devices that are not suitable for its power.

How to choose a normal car inverter and do not miss

There are frankly cheap low-quality inverters that need to be avoided. And in the rest right choice Everyone will have such a device.

The inverter is selected for specific devices that will be connected to it, and here are 6 moments that need to be considered.

1) Check the power generator power. There is a golden rule: the inverter power cannot be more than 50% of the generator power.

Only in this case, when your car is started, the inverter will not discharge the battery - at least with devices connected to it. About one half of its power will go to the needs of auto systems, so you have the second.

If you do not comply with this rule, you risk from being somewhere in the forest with a discharged battery. It sounds not too rosy, right?

Look, the converter for 750W works at a voltage of 13V - it is 58a. VAZ 10-ka at idle turns will not give such a current, so the inverter will have a battery charge and will bring you to the most inopportune moment.

The maximum generator of this car can issue 80A, but this will be achieved only at 5000 engine speeds per minute.

2) Device for it. It is advisable to carefully examine the devices that you will connect to the inverter: how much power they need on startup, as usual and at the peak.

Also consider that voltage depends on the power of the inverter, and only the most powerful can be issued to 220V.

3) Understand the model of its use. The cigarette lighter in the car usually gives no more than 100W, so when buying an inverter that will connect to it, pay attention to it.

If you need something more powerful, thinking that and how there will be to connect where the socket must be: inside the cabin or not - all this will greatly affect your choice.


Xiaomi Mijia Smartmi.

4) Pay attention to his brand. The normal inverter is equipped with protection against short circuit and overheating, Chinese unknown origin - no.

It is best looking for a suitable model in large network stores, there you definitely do not wipe something frankly wild.

If you adore Aliexpress, be sure to pay attention to Xiaomi inverters:

  • Xiaomi Mi Car Inverter Mijia (3 550 rub.) - Inverter for a cupboard
  • Xiaomi Mijia Smartmi (3 350 rub.) - Traditional inverter

Both inverters are 100W - they are connected to the cigarette room for mobile gadgets.


Xiaomi Mi Car Inverter Mijia

5) clarify the type of inverter socket. See, for example, in Xiaomi Mi Car Inverter Mijia for a cupboard is not our socket, so you will need an adapter.

But in Xiaomi Mijia Smartmi Universal entrance to any forks, but absolutely another form factor. Choose that you are closer to the soul, if you are considering Xiaomi.

6) Check out additional. Inverter feathers. Dear Inverters Suggest auxiliary weight: information screens, voltage change and USB. If this is not necessary, do not overpay.

I like inverters for the cigarette lighter with USB. On the one hand, you get a full-fledged outlet, on the other hand, do not deprive the interface to charge your iPhone.

Inverter is a complex device, and it needs to be properly used

Car enthusiasts and lovers of outdoor activities in nature many decades have dreamed so that you can take a TV and the rest household appliances. This dream was carried out thanks to the modern PWM controllers on which they began to make boost voltage converters from 12 to 220 volts. Efficiency reaches 95%, which makes it possible to effectively use the energy even a small battery.

Thanks to the Chinese, online stores are littered with car inverters 12 in 220 volts. But as you know, they love to overestimate the characteristics and sell Chinese watts.

You can read about the main characteristics in the previous article ". Here we consider the features of the automotive converters that are most popular.


  • 1. Power
  • 2. Power supply
  • 3. Form of sinusoids
  • 4. Sources of current
  • 5. Profitability check

Power

The stated power of cheap voltage converters from 12 to 220 is often overestimated or is the maximum power. The seller may just be silent about it, and you will learn about it after he burns. Most of you are not required 1000 or 5000 W, 500W is enough.

The use of the inverter is not limited to the car, you can install at home and in the country. We are primarily interested in the possibility of connecting LED lamps and LED lamps. Most readers do not want to buy specialized light bulbs and spotlights for 12V, because it is rare to use them. Rationally acquire them only when frequent use.

Periodically, I look at the change in the range in the stores, met an inexpensive car inverter 12 to 220 to 500W. The price is too low, cover the sale, is 100% sure that the store is dying.

I decided to figure out, it turned out:

  1. 500W is the maximum short-term for 1 minute.
  2. 360W - peak for 15 minutes;
  3. 240W - Real long-term rated power.

Do not install more than 300 -500W devices with your own hands, it should make an autoelectric. It is too likely that you burn something in the car.

At maximum load, you can measure the output voltage, it is weak it sends, and instead of 220 get the value below.

Never use the device at full power, leave the stock at 10-20%. The stock has only expensive converters. Take into account this when buying and calculating the load.

Thanks to the development of the Chinese industry, now many domestic brands traded with lots. Some of Russia's brands belong to the Chinese, they have already scared polim. Mortgles are taken by a ready-made goods at the Chinese factory and the name of his brand is set and sold in Russia. Therefore, the same models are sold under different names.

Without load (at idle), an increase in current converter has a sufficiently high power consumption. This indicator may be from 5W to 15W, current, respectively, to 1a. It can completely disembark your source if you forget it to disable it.

Supply voltage

The input voltage of the autoinverter is usually from 10 to 15 volts. For trucks, it is needed from 24 to 220. The thickness of the wires coming from the battery to the inverter at 24V will be 2 times less, a small plus for heavy trucks. Car must have protection against jumps in electric network Auto.

Special attention is paid to the thickness of the wires moving from the battery to the voltage converter. Small thickness can cause overheating. I usually believe that the cross section of the copper cable is equal to the amount of ampere. For example, if the cross section is 1.5mm 2, then the cable holds to 15a. If the power of the car inverter is 500W at the output, then its full consumption from the battery will be 20% more.

  • 500W * 1.2 \u003d 600W
  • 600W / 12V \u003d 50A

At maximum load on the inverter in 500W, the current over the cable from the battery will be 50 amps. The copper cable section requires 5mm 2. If it is less required, the cable will be heated, the insulation melting. The circuit of the auto accumulator is accompanied by a whole fireworks of sparks and sound special effects. It turns out the type of welding, the metal is very warm and melted.

On-board computer some auto tolerates very badly low voltage Nutrition. This happened for a long time happened at the relative on the Renault Koleos, the food was caught up and the onboard computer was burned, and the car became semi-in. The official dealer suggested only the replacement of the entire block fully cost from 100.000 rub. I had to turn to the electron, which came up for a chip for 5000 rubles and everything worked again.

Form of sinusoids

Pure sine and modified sinusoid

Some readers are questioned, what kind of sinusoid at the outlet of the 12V 220V inverter is better, rectangular shape or pure sinusoid? Due to the peculiarities of the conversion, the simplest thing is to obtain an alternating current with rectangular pulses of the frequency 50Hz. Of course it is not a natural sinusoid as in home network. Modern PWM controllers can make the shape of almost natural, but consisting of short pulses, the so-called pure sinusoid. Not every electrical appliance can work properly on a square sine. Refuse to work properly electric motors, refrigerators, microwaves.

Indicators for additional control

Clean sinusoid in the autofverter 12 220V is preferable, all electrical appliances are calculated on it, but so much more expensive. Modified sinusoid causes schemes to work in non-standard mode. The heating of radio-electronic parts increases, chokes begin to make noise. Similar results can be obtained if you dimme the LED lamp that does not support the brightness adjustment. At 160V, the LED lamp begins to flash and strongly crack.

Sources of current

..

As a power source, the main battery of the car is usually served. I often have to communicate with auto electricians and sometimes deal with the diagnosis of airborne electronics by special diagnostic devices.

I recommend to power the current converter to use a separate 12V battery. It is often forgotten to turn off the inverter itself or the load from it, and it completely places the main battery car under the hood. It lines very much, then the engine will be very difficult when there is nothing to see.

  1. rated capacity of 55 amps hours;
  2. maximum current 500A, affects the return of the current to the starter when the engine is started;
  3. rated voltage 12V.
  4. energy reserve fully charged 12V * 55Ah \u003d 660W

I know the power of your source, you can calculate the approximate time of work. Only it is not necessary to plant a lot below 11V, otherwise it will greatly reduce its service life. Keep the battery only in the charged state.

To control the remaining capacity on the case, make a window in which the indicator is red and green shows the current state.

To power the rigging transducer, the battery does not need characteristics as high starting current and stable operation at low temperatures. This will help you save money and take the tank more. Excellent parameters will be required only for operation in remote areas of the Far North, when the capacity and current are lowered at low temperatures.

Many of you know that on the "law and protection of consumer rights" some products can be returned back within 14 days if you did not like the color, shape or current of the current. I am addressed to me if you can buy a battery, to use them a week at the cottage and then return back to the store with the return of money. Get a money back according to the law will only be possible if there is no possibility to exchange on a similar product.

Checking performance

Lighting lED lamp

The service life of the autofill 12 220V depends on the degree of protection against moisture and dust. In the car there are a lot of dust, wet air and condensate. If there are ventilation holes in the case, then the contamination is easy to accumulate inside. Example serves system unit From the computer, which is cleaned every six months.

If you stopped working, do the following:

  1. read the instructions, the manufacturer could nominate with the functionality;
  2. wait until the inverter cools;
  3. check out short circuit, the wires in the electric forks are usually falling off;
  4. check the boot fuse, even if it is reusable;
  5. ring cigarette lighter fuse;
  6. look at the operation mode indicators, they can prompt a malfunction.

After buying, I recommend immediately check it on working with a nominal load. To do this, connect the incandescent bulbs, suitable power to it. For example, 2-5 incandescent bulbs per 100W. Let them work for 30 minutes, during this time the car inverter 12 220V should warm up to operating temperature, if the surrounding atmosphere is above 0 degrees.

Wattmeter Robiton PM-2

You can control the amount of watt consumed on a voltage converter indicator from 12V to 220V, it is in expensive models. It is easier to buy a household wattmeter by 220V and connect it. I use Robiton PM-2, very high accuracy up to 0.1W, other counting much worse. The cost of Robiton PM-2 is equal to the cheapest Chinese wattmeter, and the accuracy is an order of magnitude higher.

Separately embedded voltmeter and ammeter modules are sold, but they are expensive from 600 rubles. For this amount you can buy 2 most simple multimeters of type B830, B831. Then connect them how your fantasy allows, having taken the nano-zeophent to the inverter housing.

Significant part of mobile electronic devices Have the ability to power or charge batteries from the car cigarette lighter. Everyone knows and car charging cables cell phones, and power supplies for laptops and various accessories that feed on the automotive network. But in the car there is only one voltage - 12 volts direct current, which means that not all devices are able to eat from the automotive network. For example, TV, electric drill or even the usual home desktop computer We will require normal nutrition with a Euro-rosette with a voltage of 220 volts and a frequency of 50 Hz. When you want to go to nature and see there TV, work at the computer and turn on the electric lamp, you will certainly start search and car TV, laptop and 12-volt luminaires. And car accessories are much more expensive than ordinary. Take at least TVs: 15-inch home TV receiver will cost you several times cheaper a car TV with a smaller screen diagonal and much worse sound. The task is clear - it is advisable to get from the car 220 volts alternating current. That's just how to do it?

Recently, appropriate devices, inverters began to appear on sale. Speaking regular tongue, These are constant current converters to an alternating voltage with a voltage from 12 V to 220 V. Today we will look at such a device from the company NEODRIVE, a new company on the Russian market, offering customers a full range of electronic accessories for both computers and home use. So to speak, device class "Home Entertainment".

The principle of operation of the inverter

The principle of the inverter is based on the ability of a thyristor to close and erode the chain of an arbitrary supply of pulses to its control electrode. Theoretically, the inverter can issue any frequency at the exit: 50 Hz for Russia and Europe, 60 Hz for the United States or even 400 Hz for industrial instruments of special purpose. It is more interesting for us to get the frequency of 50 Hz, which employs modern household appliances for the market of Russia, Asia and Europe. Inverters have the opportunity to raise the voltage and adjust it with some accuracy. For example, inverters used in neon backlights for modding converts a constant current of 12 V to an alternating current with a voltage of several thousand volts. Typically, the inverter efficiency is 90-95%, so that these devices have not very large heating losses.

The outlet inverter cannot give pure stress sinusoid. As a rule, an approximated sinusoid is obtained from a variety of steps. But this should not be afraid, since almost all household appliances do not require the perfect tension quality.

Power consumption typical household appliances

The car inverter is an item if not the first to be as a first-aid kit or a reserve, then very useful. It is quite possible, soon cars will be equipped with a 220-in-default outlet, but while we have the opportunity to choose which device we need to be connected on hiking conditions. Based on how power you need to be powered, and you need to choose an inverter. After all, it is quite clear that the device designed for 50 watts is no longer connecting a kilowatt heater - it will simply burn. But it does not make sense to buy too powerful device to save place in the car and even more - perhaps a powerful inverter will be too uncomfortable for you. So, let's first decide with the power that you need.

Typical energy consumption of modern devices

Power consumption, W

Recorder / CD - Player / Walkman / Razor

Energy-saving lamp (equivalent 100 W)
Magnetola, cassette tape recorder

Heater 1400

As can be seen from the table, even several devices capable of helping you on vacation, will not consume in the amount of more than 100 W. As a rule, low-power devices are those that you can use constantly, even on the move in the car. For example, your passengers can work on a laptop, listen to the player or watch a portable DVD player without fear that the batteries are discharged. Naturally, the electrical outlet will be required to you in the cabin, that is, the inverter must connect to the car cigarette lighter socket. But the car wiring, especially in domestic machines, is not designed for long-term heavy loads, so in order not to fail the cigarette lighter socket, more powerful inverters are connected directly to the battery terminals.

NEODRIVE car inverters

NEODRIVE offers for users wide the lineup Automotive inverters of different power from 75 W and above. Inverters with power up to 100 W connected in car cigarette lighterso that it is convenient to use simple household appliances It seems like a laptop, television, tape recorder or electric shaver.

More powerful inverters that you can also use for heaters and for manual tools are connected only to battery terminals so as not to load the car wiring.

Accordingly, the implementation of these devices is different: more serious and more powerful looks like an industrial device and easier as a toy inverter with a power of up to 100 W. All NEODRIVE car inverters have hardware protection against overload and overheating, as well as protection against the discharge of the car battery. The inverter himself will tell you about dropping the voltage on the battery (about 10.5 volts) and when the voltage is reduced on terminals until 10.1 Volt inverter turns off the power to not discharge the battery and give you the opportunity to start a car.

Today, a 300-watt inverter NEODRIVE is languished in our test laboratory, which we now and look at.

Inverter NEODRIVE 300W.

A 300-watt car inverter NEODRIVE At the time of writing the review was one of the most powerful direct current converter to a variable from the company's assortment (there are also 500-watt models). This device comes in a transparent blister (tight polyethylene packaging).

Inverter, an instruction manual, connecting wires and a 40 amp fuse attached to the inverter.

Since this is a powerful 300-watt inverter, it connects only to the battery terminals with powerful cables with the "crocodile" clamps.

The inverter itself has an aluminum case with dimensions of 170x120x52 mm and weighs almost 750 grams. On the front side there is one universal socket with a grounding, which is connected to both European forks and Russian. To the right of the outlet installed the device and switch. As we said, the inverter has protection against inclusion on a short circuit, from deep discharge of the battery, from overheating and overload.

FROM back side There are terminals for connecting power from the battery, a fuse that protects overload and the fan. Inverter uses acquaintance of motorists fuse type.

There is one 40-ampered fuse. In more powerful inverters there may be several of them, and in less powerful fuses are calculated for a smaller current.

Connect and draw conclusions

Connecting a 300-watt inverter will be as simple as easy to get to your car battery. And it has its pros and cons. For example, in many foreign cars, the batteries are installed not under the hood, but under one of the seats or in the trunk. Access there may be difficult. It would be logical to set inverters with two types of power cables: from the cigarette lighter (with the limit of maximum current) and from the battery. In this case, for example, to turn on the TV in the car, you will not have to pull the wires from under the hood or trunk in the salon. But if necessary, you can connect the inverter to the battery and get full power.

It is very convenient that the inverter will not let you discharge the car battery. Agree, it will not be pleasant to stay in nature when the engine does not start. The instructions say that some devices will have to include several times in a row before they earn in normal mode. We plugged the tape recorder and TV - no problems arose. With a load close to the maximum, from time to time it will have to start the engine for 10-15 minutes to recharge the battery.

When the engine is started, the inverter should be disconnected from the battery to avoid damage. It is also not recommended to include it under load. That is, first plug in the inverter to the battery, and then connect the load to it.

In general, NEODRIVE inverters are devices that must be in your car along with a first-aid kit and a spare wheel. On the road, on vacation or simply in the garage, you can always get 220 volts of alternating current to recharge phone batteries and photo-video cameras, work the power tools or watch TV.

We thank NEODRIVE for the provided car inverter.
