So it delivers 4 amps at each output.
I currently have the wireless keyboard and mouse adapter, a Samsung tablet, an iPad, a Garmin GPS tracker and 2 cell phones plugged into it and have seen no performance anomalies at all.
When you think about it, the connection going from the power strip to the computer probably doesn't have anything connected to pin 1 and pin 4 where the power runs, only 2 and 3 where the data runs. The ports in the strip, obviously, and wired for +5v on pin 1 and ground on pin 4 on one side and of course reverse on the other so the hot sides mate.
