What about the fact that it charges an S4 but bit the S5?
We're looking for patterns or anomolies. Since your S5 charges from other sources, your cable and the S5 jack appear to be OK. So we move on to a differential analysis. Why does the S4 charge from the new outlet, but not the S5?
I can think of half a dozen unlikely reasons.. the most plausible reasons are polarity or an out of spec voltage. It could be that the S4 rectifies the input, while the S5 uses a DC path for instance. That would explain why only one model would care about polarity.
Actually polarity reversal is unlikely. And would be more likely a manufacting defect, than anything your electrician did wrong. My money - as to the most likely issue - is on the oulet voltage being too low. It should be +5 VDC. Perhaps the factory had a bad day and it is supplying 4.8.
The ways to design an electronic circuit are endless, so there are lots of potential reasons why one phone would cope and another would refuse what the outlet has on offer.
