So it seems that the 2 USB ports in the AC charger has only a 1A output each. The spec's on the charger say 2A 'Total' so I am assuming that's 1 amp each. They will both charge my iPhone, but not my iPad Air2, it just says 'not charging', but it charges fine on the Apple 2A power block. With the power available you would think they would have one 1A port and one 2A port (for tablets) If anyone has a iPad that will charge post up as I might just have a bad charger power supply.
