With multiple devices (iPad, smartphones ...) I had a booster battery that would allow me to function in all circumstances. Facing the accolades, I turned to the brand that promised ... Anker
Total disappointment, the device is "locked" when loading the tablets or smartphones which prevents the loading of devices - while the battery indicates full load (LED 4). The only way to unlock it is to connect the battery to the charger (current). Even this operation does not solve the problem after. If the battery is connected Anker, so she supported devices => no interest!
So I joined the club of "1 star" ...
Shame because it's exactly the product I needed.

Update 11/19/2014
Mail sent to after sales Anker to report the problem. In a week and 3 or 4 mails, a new battery was sent to me without having to return the defective battery. PERFECT !!!!!!! If only all SAV were like that ... For the new battery, it is functional. Hopefully it will better than the old.
