Effective and practical 25

Simple charger to use and very convenient. I use it regularly for my MP3 player or my iPhone and am very satisfied. A little heavy and cumbersome at first glance, it is actually not that much (especially once we got rid of the wall socket). Either you are you (or someone else) and you plug your charger to the wall in order to connect the device you wish to charge (a cable is included) or you thought charging the charger prior and in this case, you can take it with you and recharge your mobile, mp3 player or other, when you want.
The use of this device presents no particular difficulty. You can charge two devices simultaneously and it fulfills its charger Duracell battery backup feature (if you have not forgotten to load it first, of course).
