Telephone Jack convert to USB?
 
Hi,
Has anyone converted the old telephone jacks to USB outlets?:)
:)

I haven’t, but wondering about signal loss given differences in specs between wire types. USB specs call for twisted pair data lead and an outside shield, neither of which are the way old-style telephone wire was built. Would be interesting to try!

EDIT: Dawn’s on me you may just want to use them as charge outlets in which case you can ignore my concern :-)

What's your intended use? If you're charging from an external phone line, you would need to wire up an adapter, complete with a voltage regulator. Would it be easier and more effective to replace your 110 receptacle with a 110 outlet/usb outlet combo in the area you want to use it?

Tell me more...

I love this idea. Yes, it is for charging.

or something similar. You can also replace the receptacle with a combo unit if you want. They are also available on Amazon.

I use the rear TV area to charge our phones, etc. Added a 4 USB outlet (runs on 120v) next to the 120V receptacle. I don't have a picture, but in the front I replaced the no longer used passenger headphone panel with this 12 volt USB panel. Took a bit of rewiring, but nothing too bad.

I purchased this wall jack to mount next to the couch. It has HDMI and two 12v powered USB ports. The idea was to have an easy way to plug in phones or iPads to the TV without a long cable snaking through the inside of the bus:

Of course, it hasn't been installed yet, but soon...

For travel days and boondocking we stock up on these;

Our FC has 12V outlets well positioned around the inside and this way you aren't dependant on having shore power or running the generator.

I recently did exactly what you are talking about. I thought I posted it somewhere, but maybe only a comment.

My bus had two phone jacks, one by the couch and one in the bedroom. They had chrome wall plate covers. So I punched round holes in the plates with a conduit knockout punch and then installed some of these:

Ones with volt meter

round or rectangular pair

Then back in the outside cable bay, I removed the old phone jack, added a fuse, borrowed 12V from a local circuit, and used the old phone wiring to send 12V to the USB adapters. Since the phone cable has 4 wires, I doubled them up to prevent voltage drop and fused accordingly for 2*22ga wire.

Worked great and no need to pull new wire.

Now that I look at the picture, I need to do something with that useless, ugly cable TV hookup....
