good size with plenty of power

About the correct calculation of the capacity of this equipment already many reviewers have said - why me some pure practical experience. The battery has roughly the same size as our smartphones (Galaxy S3 and a Nexus 5). Thanks to the enclosed USB cable is short and Smartphone battery can still stuck together during charging relatively easily into a normal jeans pocket. S3 and Nexus 5 can be charged on a single charge approximately 3.5x below 5% again, the charge on the powerful port works just as fast as with the AC adapter. Overnight you can hang on the battery and the spare battery to the power supply and the telephone and in the morning are both loaded and blocked only one outlet.
The case looks solid processed and has not endured also our two little daughters, which often times the battery unit in the finger. I would not hesitate to buy it again - which is quite probably because the actually intended for me device depends 90% of time on the phone to my wife;)
