Choose The Best Car Power Inverters

When looking for a good car power inverter, here are some of the crucial things that you need to keep in mind.

Flexibility and Portability

Perhaps the first crucial thing that one needs to consider is how easy the power inverter is to carry and use. They come in different sizes which makes them different when it comes to ease of carrying them. Also, you need to ask yourself if you need a power inverter that will be installed permanently or one that you can plug off when needed. Whichever option you opt for, you should always consider the fact that anything that is upwards of 150 watts will need a direct connection to the DC source.

Wattage and Power

The wattage is also something that you need to be concerned about and your choice will depend on what you would like to use the power inverter for. The industry is packed with power inverters that range from as small as 100 watts to as high as 3,000 watts. The rule of the thumb is that more wattage means more power but also demands one to chuck in more money.


Performance is everything and you shouldn’t settle for anything that compromises on the quality of service that you get. Although there is no surefire way of knowing the performance of a power inverter by looking at it, there are a few ways that one can use to know if what they are getting is good or not. One of them is by keenly skimming through previous customer’s experiences on leading outlets. Luckily, we’ve gone through dozens and listed some of the best below, saving your precious time.

Features and Capabilities

Yet another thing that everyone must be keen on is the number of features and capabilities from the power inverter. Some inverters come with 1 outlet while others have up to 3 outlets. It is, therefore, crucial to know why you need the power inverter and if you need a specific number of features and functionalities before getting one. Although some that have tons of handy features tend to be pricier, there are some affordable ones that have basic features and yet still perform.

Final Verdict

If you are going on a vacation, camping or spending some time outdoors, then a power inverter will come in handy. Listed above, are some of the best car power inverters that you can find in the market today.

Frequently Asked Questions

Q: Can I connect an extension cord to the car power inverter?

A: It is technically possible to do this but it is not recommended. This is because it is not advisable to connect many devices to the inverter and an extension cord may encourage you to add more devices as long as there are empty slots. This can damage the inverter and that is why we don’t encourage you to connect an extension cord to the inverter.

Q: What capacity do I need for my power inverter?

A: The desired capacity will depend on the electronic devices you plan to connect to the power inverter in your car. If you have a lot of devices to connect, then you need a power inverter with a large capacity. Otherwise, an average capacity inverter will do if you only plan to use the inverter to power your phone and other small devices.

Q: What is the ideal surface for mounting the power inverter?

A: Any surface is ideal as long as it does not hold too much moisture. This will ensure the inverter and the electronic devices connected to it don’t get damaged as a result of water damage.

Q: Can the fuses be replaced?

A: Yes, they can. Most companies make their inverters with easy to replace fuses and as such, you can get one from your local electronic store should it get burned.
