I am going on a cross country ride in March and want to use my new GoPro Black along the way. I'll be doing some camping so I'd like to be able to charge my GoPro using the Powerlet socket on the bike. Apparently it puts out approximatley 5 amps but the Gopro suggests charging at no more than 1 to 2 amps. Is there a USB/Powerlet adapter available that will plug into the Powerlet socket and reduce the amperage?
