I still have a Power Bank with 8400mAh of EasyAcc, this is me but too heavy to carry them around with me as a precaution.
The Power Bank by Logilink is, however small (about the size of two normal lighters side by side and still 1cm in height to) and easily.
The housing looks sends, the workmanship is good. The USB ports are incorporated appropriately, keeps everything safe. Even the included cable to the expectations.
From other reviews I know that the advertised 2200mAh not correspond to what actually "out" gets. This also applies here.
The Performance:
I could full charging the Power Bank a Samsung Galaxy Ace with a 1350mAh battery from 5% to 100%. A second charging process was fast at the end because the Power Bank, the juice ran out.
A Nexus 7 Tablet with 3950mAh battery could charge 60% power bank by 20%.
After these experiments, I assume that the Power Bank can about effective charge 1400-1500mAh.
The Power Bank is not sufficient at current smartphones for a full charge, the term can, however, significantly increase and is it enough to actually go have small / easy here.
Addendum: A Nexus 4 with 2100mAh battery will be charged 80% from 15% to approx.
