According to Article Description "has the MMini AC 15 two 2.1 amp USB ports". Exactly this information led me to purchase in order to invite iPad3 and a Sony Xperia Tablet Z simultaneously in an appropriate loading time and decent cargo capacity can. When I held the charger together with packaging in his hands, I was surprised that on the packaging, a total output of 3A is specified. After Adam Riese result 2x 2.1A = 4.2A (lt. Description) and not only 3A maximum output power, as it is on the package. Consequently, not to 2 tablets are loaded with tablet worthy power, but only one and another unit with significantly less power, for example 1x 1x Tablet and Smartphone. This works fine. But it's just power moderately but still only a 0-8-15 power supply as some cheaper also, however, "pretty" and quite well processed. Nevertheless, it is ultimately useless for my purpose, but of course, is in the wrong product description, not the product itself ... For the buyer who does not want to load 2 tablets that part is fine.
