Types of Best Car Power Inverters

The main criterion by which inverters for automobiles differ is power, on which number and types of electrical equipment connected to the vehicle depend. So, voltage converters can be with the following wattage:

  • up to 300 watts;
  • from 300 to 1000 watts;
  • from 1000 watts.

#Inverters Below 300 Watts

These are weak inverters, connected both to a battery and through the cigarette lighter that can be suitable only for charging mobile phones. It is not recommended to overload them because this may lead to problems.

#Inverters from 300 to 1000 Watts

Devices of this type can only be connected directly to a car’s battery. Through them, it is possible to connect various household appliances such as laptops, televisions, microwave ovens, and so on.

#Inverters from 1000 Watts

Models of this type are acquired when it is necessary to organize construction work in conditions far from the power grid. Through them, you can connect various electric tools like drills, grinders, etc. Such AC inverter for car will be the most expensive.

Best Car Power Inverters Buying Guide – What to Look At?

Before choosing car DC to AC converter, first of all, it is necessary to calculate the total power of devices you need to connect. After calculation, resulting value can be safely increased by 30%. Power reserve should always be not only on the basis of connecting something more powerful, but also to avoid inverter working at its limit.

After that, you need to know battery capacity and generator power. If inverter’s capacity exceeds generator power – battery current will be consumed. With non-durable loads, this is not at all critical. With a longer use of devices, there is a risk of both a battery discharge and its failure.

#Input and Output Voltage

With these parameters, everything is simple: input voltage must correspond to real indicators when connected. Output, respectively, should not go beyond voltage for which connected electrical appliances are designed. Often, output voltage ranges from plus or minus 10% of 220 V.


Power is the most important parameter that determines the number and type of connected devices. As a rule, inverters with a capacity of up to 300 W are fully capable of working when connected to a cigarette lighter. High power car outlet converter must be connected directly to battery terminals.

When some devices are turned on, starting loads exceed constant output power. Therefore, a reserve of peak capacity is necessary; otherwise, there is a chance that devices that are more serious than a laptop will not turn on.

#Protective Functions

Protection against short circuits, overload, overheating, from a low input voltage and from incorrect polarity will help extend the life of both inverter and on-board power network. A low input voltage indicates that battery is soon discharging, so this function can be classified as mandatory.

#USB Ports

If you often need to charge your phone or tablet, proper models that come with USB ports. Of course, this outlet won’t be able to power multiple appliances, though it is great for digital devices.

Power Outlets

Power outlets and their number matters. Multiple outlets are a bit bulky, though they allow connecting several appliances at once. Single outlets are cheap enough, and current they provide is about 150 – 200 W.


The service life of auto inverter 12 220V depends on the degree of protection against moisture and dust. In a vehicle, there is a lot of dust, moist air, and condensate. If there are vents in case, then dirt is easily accumulated inside. So, choose a model with a high level of protection, and it will serve you longer.
