Hi. This article was extremely informative, but a lot of it was over my head. May I ask for your advice?
I recently purchased a USB wall plate http://imgur.com/yDMWUHS that is labelled front and back as 2Amp but the average output was 0.35Amp. http://imgur.com/1zGg6d4 The highest output I saw was 0.41Amp. When a Samsung Galaxy S2 tablet is plugged in it says "Charging slowly..." http://imgur.com/IOxeGHb .
When the tablet is plugged into the original Samsung charger, which is also labelled as 2Amp, the tester shows between 1.1Amps to 1.23Amps.
I assumed the wall-plate charger was just dishonestly labelled but surely a Samsung charger wouldn't be that far off, or would it?
To say I'm confused would be an understatement. Any help would be most appreciated.
