About my USB port outlets.
I got mine at Home Depot. (Ace Hardware has them too.
I'm sure other places have them too.)
There are 120 Volt Residential to 5 V DC outlets and Automotive 12 volt DC to 5 Volt DC USB outlets. So you chose what works for your different locations.


I went two ways.
One type has the 120 volt plugs combined with a pair of USB ports.(residential grade)
The others are just 4 USB Ports and no 120 volt outlets.(Automotive Grade)


What I did with the telephone boxes was replace the phone plate with the 4 USB outlets.
Mine are rectangle like the new rectangle rocker switches you find in High End Homes. So you use a rectangle cover plate just the ones used on the light switches.)
Then I took my phone wires and energized them in pairs. I powered them in the basement where the phone line use to plug into shore phone lines. Obviously I and not using any of the phone plugs in my coach anymore.

Hello Curtis, would you happen to have a link for the 12v capable input USB panels that you mentioned. I really like the idea ('89 coach) and it would be a good use for where all those phone outlets are. Particularly the one at the head of the bed that still has a phone on it!. Lol.
