Power Inverters

Run laptops, tools, and small appliances from your vehicle's 12V power

A car power inverter converts your vehicle's 12V DC power into the standard AC power that household electronics expect. It lets you charge laptops, run small appliances, or keep devices going on road trips and job sites. Matching the inverter's wattage to what you plan to plug in is the most important step before buying.

There are two main types to understand: modified sine wave models are affordable and fine for simple devices, while pure sine wave units run sensitive electronics more cleanly. We curate top-rated picks on Amazon across both types so you can compare wattage, ports, and safety features in one place before deciding.

FAQ

Do I need pure sine wave?
Pure sine wave is best for sensitive electronics like medical devices, CPAP machines, and some laptops. For simple devices such as phone chargers and lights, a modified sine wave inverter usually works fine.
Can I plug it into the cigarette lighter socket?
Smaller inverters can run off the 12V accessory socket, but higher-wattage units need to connect directly to the battery with the included cables to avoid blowing a fuse.
What size inverter do I need?
Add up the wattage of everything you plan to run at once, then choose an inverter with continuous output above that total. Leave headroom for devices that draw extra power at startup.
