Lighter/power point

[nukeworker]

I bought a lighter receptacle from walmart so I can plug in stuff like a GPS or CB radio. My question is; I need to know how much amperage they use. I've got the Watson's kit and I was wondering where I should plug the red wire into it. 10 amps, 20, 30? It seems like a lighter would draw a lot of current but I don't plan to use it for a lighter, just the GPS or CB.....maybe one of those small air compressor/tire inflaters. Thanks in advance.

Most electronic items like GPS will have a label on them that tells you the amperage.

I would size your wiring and fuse size to about 110% of the largest load that will be on it.
