Important Features

Ports (Outlets)

One of the most important things to look at when you’re shopping for the best power inverter for cars is the number of ports or outlets. This will determine how many devices can be connected to the inverter.

Most of them will come with both USB ports as well as a standard plug outlet. This will make it possible to charge both your phone and laptop simultaneously.

Always look at the number of ports and compare it to the number of devices you need to charge in your vehicle. Keep in mind that more ports would result in a more expensive inverter and one that would come with a higher power output.

Wattage (Power Output)

For small electronics, such as your smartphone or camera batteries, a smaller wattage would be sufficient. Look for an inverter with a range of 150 up to 300 watts of output.

For charging larger electronics, such as a laptop, you would want to look for a higher wattage or power output. With this in mind, look for an inverter with a minimum of 1000 watts to ensure you always have enough power supply.

Sine Waves

It’s typically possible to choose between two different types of inverters – those with either modified or pure sine waves. Always look for modified or pure sine waves when you’re browsing these charging devices.

Otherwise, you run the risk of damaging your electronics if you’re using a device that has irregular waveforms. Don’t forget to check out reviews to see what other people have to say about any of the inverters that you’re interested in using.

Size & Weight

It’s also worth considering the overall size and weight of one of these charging devices. Since we’ll be using it in your car or vehicle, you probably don’t want something taking up too much room or being too heavy and unmanageable to use.

When you’re looking at the different inverters, double check the dimensions and weight. This will make it easier for you to find something small, portable, and lightweight that’s better suited for using in a vehicle.

Safety Certification

The last feature worth mentioning is the safety certification that you should keep an eye out for. Look for a stamp or marking from a local safety certification provider.

This should give you the peace of mind that the device isn’t too likely to overheat, short, or suffer from electrical faults. North America has these safety guidelines and many other places around the world follow similar guidelines for safety certification.

Helpful Tips

  • It’s a good idea to disconnect any extra loads or power draw from the inverter when it’s not being used. This helps to both protect your car battery and prevent the device from overheating.
  • Make an effort to avoid leaving the power inverter sitting in direct sunlight or next to any heat sources. It’s a good idea to leave it underneath the seat or in a place that’s protected from these potentially harmful elements.
  • On older vehicles, always disconnect the inverter whenever the vehicle is being switched off. It’s possible that the inverter can keep drawing from the battery and you could end up with a flat battery the next time you go to start your vehicle.
  • It’s possible to use a secondary battery for powering a car power inverter. In this case, check that the battery is well sealed and that there is enough ventilation in the vehicle.
  • Get into the habit of starting the engine before plugging anything in or running the inverter. This helps to save the battery from flattening out and gives the vehicle enough time to charge everything before you start drawing power.

Frequently Asked Questions

How Do You Hook Up a Power Inverter?

Generally, these devices are simple and easy to use. Hooking it up will depend on the size of the inverter itself and the set up inside your vehicle.

Most of the smaller ones are designed to plug directly into the 12 volt outlet. With this setup, they likely won’t draw more than 200 watts from the cigarette lighter socket.

For larger inverters, these are typically designed to connect directly to a vehicle’s battery or to another battery. Most people aren’t looking for something this heavy duty, although there are plenty of videos and helpful guides online for installation help.

What’s the Difference Between Continuous Power and Peak Power Outputs?

Continuous power output is the average wattage that an inverter is able to supply under normal operating conditions. The peak power output is the wattage that the inverter could supply for a specific period of time.

Depending on what you’re charging, it may be worth paying attention to these different values. However, most people would be fine just following the continuous power output since they’ll likely be charging basic devices like a laptop or camera battery.
