I make these, simply connect to your portable electronics battery (or any other 12 to 24 volt battery) and gain two USB sockets to charge any USB compatible device or power any USB accessories.

Dual USB sockets allow you to charge phones, tablets, gps, cameras and power USB fans and USB lights etc.......anything USB! Mounts to top of battery (with included foam tape), piggy-back terminals allow you to connect the adapter to the battery terminals and still allow connection of your portable electronics etc..

Can switch out F2 piggy-backs to ring terminals if needed.

$20 shipped/mailed right to your door!
