12 volt charger and Nexus 7

[Philpott]

Hi, what size fuse should I use to charge my Nexus 7 onboard Dura Mater? Different fuses for different things, right? How about for a laptop? Should I switch out the fuses? My standard Horizon handheld X270S radio came with a charging cradle and 12 volt plug. On the box it reads: FBA-25A and E-DC-19A; what the ? It is a code that I can't figure out even after reading Don Casey's Sailboat Electronics Simplified. Thanks

You are probably using a 12V automotive to USB converter, so to be on the safe side I would put 1A fuse on the 12 V side. Or maybe 2 amps to give a bit more head room.

Thank you, David. And only 38 pages to read. I hope there won't be a test afterward. That part about PID bytes and different standards in China, well gosh, my head is just spinning. I'll put in a 2amp fuse and hope for the best.
