Philmore Heavy Duty Cigarette Lighter Plug with Binding Post 48-521

This cigarette lighter plug should be in every ones tool box or glove compartment. It works great for testing 12 volt equipment in your vehicle. Just unscrew the binding post and stick bare wires into the positive and negative terminals to power radios, small amplifiers, lights, or anything else you have that requires 12 volts and doesn’t draw more than 10 amps. If your equipment has wires with preinstalled banana jacks its even easier. If you have a cigarette lighter plug that keeps blowing fuses, you can quickly replace it with this plug. Just cut the old plug off and strip the wires and identify the positive and negative wires. One way to identify the positive wire is to trace the wire inside the old plug that is hooked up to the fuse or tip of the plug. Once you have determined the positive wire, unscrew the red binding post and stick the stripped wire through the hole and screw down the binding post for a tight fit. Repeat the same process for the negative wire. No soldering or blindly sticking wires into holes. This cigarette lighter plug does not change voltage.
