Using P-O-what?? Power Over Ethernet!
Keeping your wall mounted iPad charged with a regular charger and USB lead is only possible for a total lead length of about 3 metres. It depends on the thickness of the wires used in the cable, but try to run it too far and it stops working. Power Over Ethernet allows you to power your iPad over distances up to 100 metres, freeing you from having to choose a location near a power outlet.
