The usb adapter I'm trying to use is a scosche brand. Stamped on the side of the unit it reads, Input:12-24VDC,0.5A Output:5V,1A. The fuse that came with it and the pack I had to get to replace it read, 2A 250V. Now the fuse in the usb unit blew just by plugging it into the bike and car. Should I be using a smaller amperage fuse from the battery to the cigarette plug? Maybe the 15a fuse is letting too much juice go through?
