(A) full load

Because phones tend to have to be charged always in the most inopportune moment, took his leave also for me to buy a Power Pack (well, actually there are two: one for the backpack and a - so I thought - on the wallet). So I came to this here.

Plus Minus Well:
+ The integrated charging cable of Pack Phone: makes sense and with the dimensions of the small gizmo can be the phone also keep phone both as a pack. When not in use, the connector can be inserted in a built-in tab. For pure dirt. It makes sense.
+ Capacity: my China phone is once completely full and the remaining capacity reached again for about 15% battery charge
+ A charger for the pack for charging to a USB port is included.

o "credit card size": since I assume that credit cards are uniform in size in the world, I seriously wonder how the record in the product description. By credit card the thing has certainly nothing to do; rather with pink driver's license and identity card old. "In the wallet stuck" works for me not, anyway. Pocket is ok.

- I currently unknown; remains to be seen whether the capacity is retained longer.

Conclusion: as an emergency backup for your own phone very well suited for extended tours or several devices not designed or useful.
