On the one hand the
COM PAD Power Bank 6000 Mobile Smartphone USB spare battery charger
and the
Lumsing® 6000mAh Ultra Slim Portable Power Bank External Battery Pack Backup Charger with aluminum alloy Body Design Silver & Blue
the latter is the clear winner,
had tested both batteries repeatedly ung each loaded my old Ipad2 so,
The procedure was always the same, the iPad used to alert that it has only 5% battery power, connect the battery in flight mode, simply charging him until the battery was empty.
Result:
the Lumsung was empty after 4 hours and 14 minutes and has the Ipad loaded to 82%
the Power Bank was empty after 3 hours and 21 minutes and the iPad charged up to 61%
Conclusion of Lumsung brings 21% more power than the Power Bank.
This corresponds to about 2 hours longer watch movie or go on the Internet, so 5% variation but I would still find fine 20% less power for the same money is wrong.
For design, I want to write that the Power Bank is 34 grams lighter than the Lumsung
but stupid in a shirt or jacket pocket is because of the small thick design than the larger but shallower Lumsung
This is certainly a matter of taste but if you travel and need while running shop has the benefits.

From my own experience I know that decreases the performance of such batteries over time, so it may be that I still change my vote over time (up or down)
As so much is at market check:
This test is not necessarily representative because only one device has been tested!
But the other 19 reviews Currently there are just as much / little;)
