Buying Guide for Best Power Inverter for Car

Why Buy A Car Power Inverter?

Asking questions before investing can be an excellent way to get the best value for your money. If your question is "why should I buy a car power inverter?" then the following guide should suffice:

  • A reliable supply of power – have you wanted to use a computer or tablet, but the battery was down? A power inverter would help in such a case because you can use it to draw power from the car power supply system. The good thing is that you can use it to charge as many as two devices simultaneously.
  • Makes outdoor activities convenient – for those who love outdoor activities, power inverters are great! Why? Well, you can use them to power various types of devices, including blenders, kettles, and more.
  • Easy to maintain – car power inverters do not require a direct power line to the house or fuel to run. They draw power from the power supply system in your car. Equipped with one, you can be sure of a reliable supply of power – perfect for addressing your daily power supply needs.
  • Eco-friendly – car power inverters won't produce fumes when in use. Plus, other wastes such as harmful rays and more won't be an issue.

Common Types of Car Power Inverters

Single Outlet

These are the basic power inverter types and can provide 150 to 500 watts of power. Usually, they feature a small, portable, and compact design. Plus, these devices only support the charging of one device at the same time. Often, these inverters are also affordable and come with basic functions.

Multiple Outlet

These are the types that have many power supply outlets and are suitable for those who have many electrical devices. That said, the only issue when using these types is overloading or overheating complications. Most brands have included electrical safety protection mechanisms to help combat such a problem when it comes to power supply issues.

USB Outlet

USB outlets let you use USB compatible devices such as tablets, MP3 players, and more. Furthermore, USB ports provide sufficient power for only the small types of devices. However, they are not reliable for use with household devices, or those that require lots of energy.

Key Features


This is a metric that determines the power level your inverter can produce. It's a metric that will determine the type of device you can power at any given time. If you want to change a small number of electronics, then consider a 150 to a 700-watt inverter. That said, if you spend most of your time outdoors with your car, such as during camping, then go for the types with bigger ratings. These include ratings that are above the 1,000-watt rating level.


Remember to determine the number of devices you can connect to one inverter. Usually, a significant number of inverters come with USB ports and AC outlets, which you can use to charge different devices. These can include applications such as charging your phone or laptop simultaneously. Even more, the number of ports required is directly dependent on the number of devices you own. If the inverter has several ports, then consider an increase in costs.

Sine Waves 

Most brands come with sine waves, which have specific ratings for the best power supply. Why? It’s because most damages are prone to damage due to inconsistent waves such as the square waveforms. When it comes to the modified sine wave types, you can be sure your device won't be exposed to excessive power or stress. Furthermore, pure sine wave devices are also highly efficient.

Other Considerations

  • Safety certifications – the best would be to go for products that have an ETL stamp. The stamp indicates the inverter is suitable for use anywhere and based on specific safety recommendations. It's a stamp that ensures the inverter can protect against the common electrical issues. 
  • Size and weight – you want won't a device that consumes lots of space in your vehicle, unless you have a big car. A compact power inverter is ideal for your vehicle, and they are often compact enough for you to move around.

Top Brands


Started in 2007, Bestek Ranks among some of the best electrical accessory and household appliance brands in the world. The company has several branches around the world, including the UK, the USA, and Japan. We have one of their products on this list, which would be the BESTEK 300W Power Inverter DC 12V to 110V AC.

Other Key Factors

Surge Rating and Continuous Rating

The two key factors to consider in power rating would be the surge and continuous rating. It’s a metric which means the inverter can accommodate a specific power load for a particular time. Usually, the capacity for surge changes is different because of various factors. 

In some cases, the level of variation might be as little as 20%, or higher than 200%. Before investing in a power inverter, remember to consider this perspective. On average, a power surge that averages between 4 to 30 seconds, should be adequate for your devices. A good example would be the motor on your pump 

The most popular types you will find are the ones with low surge ratings. Why? Its because they are suitable for high-speed electronic switching applications. Furthermore, they have power ranges of between 25 to 60% of the optimal load. Even more, a significant number of the affordable inverters have a power range of between 100 to 5000 watts are the low surge category. The types that have large surge ratings have transformers and are not efficient to use.

 Even if high-frequency switching inverters provide low surge capacity, they are also beneficial in many ways. For instance, they are small, affordable, and easy to move around.
