As already revealed the technical specifications for size and weight, the battery is not particularly small and compact yet lightweight, so rather not pocketable and also more likely not for weight fetishists.
For this, however, the PowerPack offers pretty good energy reserves - and at the end it seemed to for my purpose.
The unit makes a solid quality impression and is handled properly.
Well I also like its easy to read digital display to indicate percent state of charge. Exactly because of this information ultimately fell my choice on this product. So far, everything funzzt fine.
The battery is supplied as specified without a charger.
The battery pack for my Samsung Galaxy Note is used 8 (=> 8 "inch tablet), which I use on a bicycle for navigation and orientation with various card-Apps.
With GPS and Display / illumination always on the power consumption of the appliance is nevertheless significant. 8 hours of operation are hard to create. Now with the Power Pack I energy sufficiently.
Charged is the battery easily via the standard charger of grade 8 (=> 2A).
For the connection Note 8 to the battery pack but I do not use the supplied USB cable (which can not comment) but a cable by Delock with 90 ° angled plug on Micro-USB connector. The sensitive USB jack on Samsung becomes something spared compared to a straight connector with a corresponding lever.
In order to protect against environmental factors (=> dust, rain etc.) plugged device and battery in each one DIN A5 document bag from Ortlieb.
The grade 8 can be downloaded both via the 1.3A and 2.1A the port. In Radl operating 1.3A just fine, the Note 8 is in this case yet charged.
A completely empty Note 8 is can be recharged well 2x. Personally, I avoid it but to suck the batteries from grade 8 or Power Bank completely empty.
