I want to wire a 12v power adapter straight to my battery for the sole purpose of charging my cell on an upcoming trip. It won't be kept on after the trip so I don't really need anything fancy and will probably purchase one at walmart or one of the local auto stores.
A couple of quick questions for the smart folks out here:
1. If there is nothing plugged in to it, will it drain my battery when the bike is off?
2. Do I need to wire in a fuse of any sort if I just want to power my phone or can I just go straight to the battery? If so, what size?
That's all. Just want to use it for one trip and then take it off. I know nothing about electrical stuff, so that's one of the major reasons i don't want to tap into wires and make it more permanent.
Advice is appreciated.
