Power insufficient for 2 Apple devices

The charger has not enough power to two Apple devices (iPhone 4S and iPad 3) to load at the same time. The charging is interrupted. I now have a unit of Kensington () in action with the 2 * = 2.1A 4.2A more than twice as much electricity can provide, even at Amazon is available and that is what makes what it should: fast charging with full power, without thereby overtaxing yourself.

So if you spend a few more euros and wants to buy good quality really, is well advised with the "Kensington Absolute Power Dual USB Wall Adapter" (4.2A). The Belkin Adapter with 2 * 1A = 2A can also be useful in the special case for low-power USB devices, as cheaper.
