Determine the total amperage your AC devices will consume, and obtain a power inverter which supplies more amps than the largest device consumes during operation.
Use the supplied power cables and mounting hardware to connect your inverter to your vehicle's battery posts. If a fuse is supplied, install the fuse as the inverter instruction manual explains, so your inverter and devices are protected from any power spikes.
Turn on the power switch of the inverter and then plug your AC power devices into the wall-style outlets which should appear either on the front or on the back of your chosen inverter unit, and then turn the device(s) on to use as you normally would.
