I bought this device for my MP3 player, otherwise the load constantly the PC must be. With each. due to time constraints uncompleted USB charge via PC you presented a charge cycle and thus inevitably reduced the life expectancy of accumulators are. Quite different in this device, here I can choose the loading times regardless of my time on the PC and can, for example at the outlet fully charge the battery at your leisure, overnight at 100%. Even on long trips, you can load the USB devices. So much for the benefits of the device! I forgive only 4 stars because I think that the material could be a bit higher quality. It's sometimes quite fiddly to fold 230 - to get plug into the socket as this will collapse again. An arrest would have been useful here. Moreover, while an LED light while but you get no indication when the charge is complete. All in all, a very useful part of which I at the price would buy again.
Addendum of 23/09/2010 I have the part has been for over a year, but as I do not often use the dedicated MP3 player it was a total of maybe 20 times for use. Now get the fold 230 - plug no more contact. When I plug the adapter into the plug the led briefly once, and that was it also. A shop is no longer possible via the outlet. Since one part but not without destroying it, can open in order to eliminate an error caused by the inferior mechanism loose connection itself, the part now heads into the bin. Because of the aforementioned advantages of the equipment I have now another device ordered me at Amazon without folding mechanism. I can only all interested parties at home outlets with child safety, whether integrated or glued, strongly advise against the purchase.
