USB under back seat

[scotchjeff]

Hello, I would like to keep my battery jump box under the back seat...but I would like a USB port under the back seat to keep the jump box charged at all times.
What is the easiest way to install a USB port under the back seat...I know there is a ton of electrical...I figure someone in this group knows the best idea or has already done this.
I used to keep this little jump box in the center console of my Ford Expedition...but this group knows why I can't do this on the Grenadier.

A long USB cable??

I have a jump box that I put on the charger once every 3 months. It holds the charge and usually down only two bars. Two bars gets me min of 5 jumps.

I would recommend not keeping it on a charge for extended period as it wears out the jumper battery.
