As is the case with the Sony CP-F5B? Of course he has to be himself first charged, at least when their own residual charge only is low (the orange LED indicator blinks once). This lasted for about three hours.
Thereafter used. A Sony Xperia Z was charged in about two hours. After the battery pack to more than two-thirds was empty; it was enough then just to charge a small MP3 player. There can be only one device to charge, but you can simultaneously charge the battery pack and power a USB device with power - quite useful, if for example in the hotel rooms only an electrical outlet is available. However, no (USB) -Netzstecker is included, the you should have yourself.
Pros and Cons At a Glance:
+ Loading time is relatively short
Battery pack and a device can be charged simultaneously
- Only one USB port available
not supplied power cord
too little capacity
