Aesthetic side the battery is finished, but the design is not great: when charging the 4 LEDs do not indicate the progression comes on the one hand but to say that a bear and then go off when full it is no way to know if this is the beginning or the end of the load. The battery is fully charged oddly happened then what was new !!! During the first charging LEDs are extinguished is immediately making thought there was a defect in the cord of the charging transformer. when loading a phone you have to press the button under the LEDs to start charging. having no other tip as I tested comes to load other device with 5V: iPhone ok ok sansung a mini tablet ok Archos tablet ok nokia ok sony ericsson (the battery starts to load but is off after a few seconds) There are tip for DS and 3DS consoles mintendo (to be tested) the charging time is quite fast between 4 to 5 hours, contrary to what I read on another review (about 6 hours) Supply side 9 / 12v, I have not had the opportunity to load but just tested for the presence 12v unit. the supplied USB cable very short and allows the phone away from the battery.
The principle of the backup battery is very convenient, having the battery in the backpack, it recharge his phone outdoors or when the outlet is far away and we want kept its self next to the phone ( for example).
Finally, information and operating load deserving improvement.
