How To Choose A Power Inverter?

Auto inverter

Auto inverter

It is not hard to find a good car battery inverter. In this section, we will explain all factors that decide the best car inverter.


Do you need the best power inverters for RV or the best power inverters for camping tools? Or do you simply require a standard vehicle inverter for regular purposes?

Remember that each automotive inverter has a specific power that works with different types of devices. You need to check the power rating of every product to find the suitable one for your car.

The rating of inverter power is in watts. The higher the watts are, the more powerful devices a converter can support.

If you only need a car inverter for a laptop, smartphone, or table, a 100w inverter, 140 watts power inverter, or a 200W power inverter can already please you at best. These devices don’t require a high number of watts to run.

But for large camping tools, such as coffee makers, TV, refrigerator, air mattress, a regular power inverter for a laptop won’t suffice. You require a 400 watts power inverter, a car inverter 1000 watts, or one with a higher power.


The next thing to consider is the outlets of the vehicle power inverter. Each product contains a number of different outlets that provide specific outputs.

A normal automotive power inverter usually comes with a car DC to AC converter. It features multiple AC outlets. Several models may have USB ports and many other types of outlets besides the AC.

For example, as you use a 12 volt inverter, you may notice that it has the following outlets:

  • 12 volt to 24 volt converter
  • 12 volt to 110 volt inverter
  • 12 volt to 120 volt inverter
  • 12 volt to 220 volt inverter
  • 12 volt to 240 volt inverter
  • DC to AC converter for car
  • AC to DC converter for car

The Bestek 300w power inverter above even includes a power inverter for the car cigarette lighters. It has a special plug that supports only a cigarette.

Types of Car Power Inverter

There are many types of inverters for different types of vehicles. You need to consider whether you require the best power inverters for semi trucks, the best power inverter for a work van, the best power inverter for a pickup truck, or one for regular automotive cars.

As you know, different vehicles are equipped with a specific power supply. The input of the converter must accept the output of the vehicle power source.

A regular 12 volt inverter for a car can accept a power of 1,500 watts. While the same 12 volt converter for large trucks may require a capacity of 2,000 watts or more.


There are many things to consider when checking the cables of a portable power inverter for a car.

First, you need to check the length of the cables. The cord needs to be long enough for a good plugin. The length will depend on the size of the vehicle. For example, a power converter for a truck usually has a longer cable than a power converter for a car.

Secondly, you should check the material of the cable as well. The cord should have sturdy construction to avoid corrosion, tearing, or scratching.

For example, a good 12 volt battery inverter is usually covered in rubber or neoprene. These materials are highly durable and insulated.

Cooling Fans

No matter if you use an inverter for a car cigarette lighter, a car power inverter for laptops, or a converter for heavy-duty devices, always check for the cooling fans. The reason is, even at low power, the converter may still get hot after a long period of operation.

If the inverter overloads, it may start some issues and cause heat hazards. Cooling fans will help prevent this terrible situation.

Safety Features

When buying an electronic device, you should always keep an eye on the safety features.

Most products offer an insulated cable. It will prevent the electric current from hurting your hands. Also, some high-end converters may have an auto-shut-off system. Whenever the inverter overloads or runs out of battery, it will stop working.


If you buy products from popular companies, you will get a warranty along with the inverter. The question is, how long is the warranty effective?

Standard warranties are about 18 months long. Some expensive products will have a longer warranty, which is about 3 – 5 years.


Using Tips

How To Install A Power Inverter In A Car?
