interesting Walmart find
Killing some time in Wally world last night, I found an add on power port/ 2 high amperage USB outlet stand alone/ add on device. The unit has 12volt pigtails to wire into the Airstream directly.
It is a very tidy little outlet that could be added anywhere and everywhere!
I found this in the auto department with the wire connector/ electrical tape/ zip tie stuff.
At $9 you could wire a zillion to keep your digital world charging and powered up.
