Best Power Inverter For Car

For people who are constantly on the go, a good power inverter can be a lifesaver. These devices convert low-voltage DC current that is generated by cars,  boats or other vehicles into an AC that is similar to that found in a typical household power outlet. By doing so, the power generated in vehicles can be used for charging and powering many devices on the go. Whether you’re looking to charge your laptop in your car or power a TV on your boat, a good power inverter can make it happen.

In this guide, we’ve put the best power inverters that are currently available on the market. However, power inverters have many differences that set them apart. You might get a really good power inverter and not like using it in the end as it isn’t the best choice for your particular needs. Before you buy a power inverter, there are a few things that you should keep in mind in order to make the right choice. You might also be interested in our articles about the best obd2 scanner and the best power conditioners.

1. Inverter vs Inverter/charger.

When you’re buying a new inverter, you’ll have to choose between an inverter or an inverter/charger. Which one to choose depends on how you plan on using your new power inverter. In a nutshell, normal ones are meant to be used with a vehicle’s battery. The DC current that is generated by the vehicle’s battery is converted to an AC current that can be used for charging and powering different devices. On the other hand, an inverter/charger is meant to be used as a backup energy source in case of an emergency. If there is a power outage, these inverters/chargers will kick in with the energy that they have already stored. Before you buy an energy inverter, you should think about how you’ll be using it to make sure you get that’ll get the job done.

2. How much energy do you need?

All power inverters produce AC power. However, they don’t produce the same amount of power. In other words, a power inverter that produces enough power to charge your laptop might not be enough to power a fridge and a TV. Before you choose a power inverter, you have to know how many watt outputs do you need. Calculate the watts that your appliances need and compare that to the power inverter output to make sure it has a power output that’ll have you covered. It’s better if you aim for something with an energy output that is a little higher than what you need to make sure that you’re on the safe side. You also never know when you might need this extra power.

3. Input and output voltage.

Another thing that you should make sure of before you buy a power inverter is that it’s compatible with the AC current that you have. Based on that, you should choose between 12V and 24V inverters to get one that’s compatible with both your AC power input as well as the power needs of the gadgets that you use. You should check separately but the general rule is that most of the Americas use 120V AC power while the rest of the world use 220-250V. Now that you’re familiar with how to choose the right power inverter for your needs, let’s have a look at some of the best model that is currently available on the market.
