So it appears the 5v wall wart USB outlets are fried.
A future solution can be a 12v to 5vUSB outlet, that way they phones still charge if the power goes out.
I've been very happy with this unit:

That model actually counts amp hours consumed on several different devices, but that feature is a bit clunky.
Here is a professional review:

These pass data and have the least voltage drop, and when I use it with that Blueseas 12v to 5vUSB power supply, charge My S4 Mini significantly faster than the Samsung provided cable and 120Vac USb power supply.
