Inverters For Vehicles

Vehicle power inverters help bring electricity along for the ride, whether you’re checking fence lines, heading to a jobsite or setting up camp for the weekend. An inverter converts direct current (DC) from a vehicle’s battery into alternating current (AC), giving you a way to run compatible electronics and equipment away from a wall outlet. For many cars and pickup trucks, that means converting 12-volt battery power to the 120-volt AC power common in U.S. households, though you’ll want to confirm your vehicle’s electrical system before choosing an inverter. A car power inverter can be handy for charging a laptop on the road, while a truck power inverter may support tool battery chargers or other equipment within its output limits. Start by adding up the wattage of everything you plan to power at the same time, then check both the inverter’s continuous output and its surge rating. Continuous wattage covers the load it can carry during operation, while surge capacity helps account for the brief startup demand of some motor-driven equipment. Leave room above your expected load and check each device’s power requirements rather than choosing by outlet count alone. Finding the right inverter for your vehicle also means matching its connection type and electrical output to the work ahead. Lower-power vehicle inverters may connect through an accessory socket, but the socket’s rating and fuse limit how much power you can draw; higher-output setups generally require a properly fused battery connection installed according to the inverter and vehicle manufacturers’ directions. Pure sine wave inverters provide an AC waveform similar to household electricity and may be required for certain sensitive electronics, chargers and motor-driven devices. Modified sine wave inverters may suit some loads, but check equipment compatibility before plugging anything in. Keep your vehicle power inverter dry, secure and well ventilated, with clearance around its cooling openings, and follow the specified cable size and fuse requirements. Battery capacity and the vehicle’s charging system affect how long you can run your gear, and drawing power with the engine off can leave you without enough charge to start. Never idle a vehicle in a garage or other enclosed or partially enclosed space to supply inverter power, even with doors open. With the right power rating and setup, an inverter for a car, truck or RV can help keep essential gear running wherever the day takes you.
