... Especially on the negative. 1. Before for as a still valuable device as an I-Pod Nano or a cell phone (something not cost you just a few times EUR) uses an external power supply, it is worth exploring at least the technical data of the power supply and the local device , these parts are also working often together via internal electronics / micro-computer and that should be kept in mind before speaking of "China-scrap" 2. This power supply has, although it does not look like it, 3 apart quite output power quite like this that the equipment manufacturers, at the device you want to connect the, in such a case, any warranty and guarantee rule 4. As for the heating, it is when the enclosure exceeds the hand warmer, or about 30 degrees in virtually all electronic equipment critical. These power supplies are just just "felt" warm, even at "full load", are so well dimensioned. Otherwise, I can absolutely recommend the part given the price and the performance. I have 4 of them in my "laboratory" tested for about 2 hours, they bring about 5.2 volts (what is there for "voltage fluctuations", I can not determine, on the contrary, I have these things maxed right), the power However, is "only" about 700-900 mAh, is within the technical tolerance, but just right for a power supply would be better (for a loader), a voltage of 6 V, but that would be too much again for a power supply for USB devices , so ... By the way, the computer USB port brings about 5.1 V (so much for "Universal Serial Bus Specification"). And the quiescent current, so the consumption of the off consumers tends to zero, is below 0.02 V, which is the value that could be measured by my energy meter, which indicates once again for the quality. And how now - at least for me - has been found, this part is also suitable for the Kindle, invites him even faster than the Chargers offered for the bargain he locks the Kindle when charging is not to be used, so it is a real power pack. Tested but only with the "Ur-Kindle". But anyway, absolutely take seriously the phrase "only the provided AC adapter to use" because as I said, now also power supplies and the devices will work, also is not any power supply, a switch mode power supply (to determine whether this is one that you would have it dismantle, but everything suggests), and not every device has a protection against an oversupply. They were perhaps a little too much "evidence", but that had to be. By the way, even a supplement to the more than one USB port. Take a passive (ie without power supply) USB hub, which acts then as a distributor (without guarantee, has with me but works well, but you should - unlike a 230 volt distribution - pay attention to the power at which low voltage) Happy using :-))
