This meter has proven helpful in my understanding of why some outlets charge various USB devices faster than others, and that the quality of the USB cord, and its length can make a huge difference.

This linked meter can test voltage at the end of a micro USB cable, and the voltage drop can be significant.

Gee thanks.... There's another $10 I need to spend.. You're correct about chargers and cords. I'm finding out why some things charge, others done, and the differences in wall worts. It's amazing the charge differences in various devices

A lot of those built into outlets only have a 1A charge rate so they aren't strong enough to charge many smart phones.

I installed these

You need one of THESE

If you are plugged into the grid with converter going, then a 12v USB port is fine and dandy, and if you do not have grid power then a 12v USB port is more efficient.

Mine holds 5.14 volts under maximum load. Can't say the same of other USB sources I have.

Lowes has what your looking for. You can either replace the present AC outlet with one that has both AC and USB or buy a plug in module that has both also. I replaced one outlet with a USB only that has 4 USB outlets.

You can buy them at Home Depot, but they're not cheap, and need a box as opposed to the modular outlet in allot of RV's. You're way better off with a high current dual USB wall wort
