Portable electric power means having an electrical power source that can easily be moved from place to place. A 12-volt car battery is a portable source of DC power. Having a portable source of AC power involves adding a second device to the equation, called an inverter. Inverters are designed to change DC power from a battery to AC power, which is usually delivered through an electrical socket. Having a compact combination of a battery and power inverter creates a very mobile and versatile power plant.

Mount the power inverter to the side of the wooden box using mounting screws and the screwdriver. The inverter receptacles should face you when looking at the side of the box.
Drill a small hole in the side of the box behind the power inverter. This hole should be large enough so that the inverter power wires can be routed into the box to connect to the battery. if the inverter has battery clamps, cut them off to get the wires into the box.
Strip a 1/2 inch of insulation off the ends of both red and black wires. Attach an alligator clamp connector to each of the two wires, using the screwdriver to loosen and tighten the wire connection.
Attach the red wire to the battery's positive terminal and connect the black wire to the battery's negative terminal. The alligator clamps should clip onto these terminals. Finally, turn the inverter on.
