Top 5 Best Power Inverters for Cars

Power inverters provide power for accessories that USB ports could not offer. Even if brand new cars offer USB ports for charging mobile devices, they can’t offer enough power for larger accessories. With power inverters, you can provide household AC power perfect for charging laptops, small appliances, and camera batteries. If you are planning to go on a camping trip or even tailgating, you can take advantage of a power inverter for smaller appliances such as a small TV or a coffee maker. 

Power inverters are very useful as they convert the DC electric power of your car into AC electric power. Life is much easier when you go on the road with a trusted power inverter. You have more flexibility because you may bring small appliances on your trip.

When you shop for a power inverter, you may notice different types with technical details that you may not bother to read about. We came up with our top 5 best power inverters for cars to help you with your decision-making. 

#1 KRIËGER Power Inverters

They have been a reputable company that creates products for companies such as Energizer. Their power inverter lineup is highly regarded in the market. 

The safety features such as temperature, short circuit, and overload protection make the KRIËGER power inverter a reliable choice. This product also comes with an LCD display where you can see the battery level, output wattage, and input voltage.

The inverters are directly connected to the battery of your car. This can help draw more power. This model has two 2.1A USB ports and two standard AC outlets. It also comes with a cooling fan. For your peace of mind, the product also has a UL certification from Metlabs. 

KRIËGER’s power inverters come with a parts and labor warranty of up to three years. This is a great offer aside from the product’s wide range of power offerings, safety features, price point, and included installation kit. The only reason that some car owners might look elsewhere is that this product needs to be connected under the hood. Overall, we highly recommend KRIËGER’s power inverters.
