The voltage and current in a USB charger are limited internally. The wires running into the back are 12v
. Amazon sells a number of marine 12v
. cigarette lighter sockets that are a single hole or a 12v socket paired with a USB socket. If you have access to the back of a USB you can spare, see if there's just leads pushed on to spades. Pull them off and replace the fitting and plug back in (Keeping polarity in mind.) They may be fused at the converter, so don't count on 15 amps.
