If I'm honest: Charging via USB is for me partly a closed book. I specially bought myself a small USB-meter for voltage and current, to find out why the store sometimes "back takes a little longer". As the main culprit I could so after all, ever identify the charging cable, the partially loaded only with minimal power. Under maybe 20 different cables were just 2-3 left, showed good values. Short cables with thick cross-section are to be preferred, but there are also exceptions. Even and especially "original cable" that come with the tablet, smartphone or even the Power Bank, no guarantee short loading times.
But also my tablet so I could expose a bitch, which loads only fast if the USB cable already is under tension when plugging. Maybe I will one day have to understand the extent to which equipment and loaders "entertain" a suitable cable as to which is the appropriate charge current and probably why the charging current is changed from time to time in both directions.
Since the Power Bank can nominally more power available as the consumers take my hungry art, I have two devices connected to test on the meter at the same time on one port - of course with my two best cables.

This Power Bank, the manufacturer has put much emphasis on the outward appearance: The aluminum case is really processed very noble and immaculate. Also, the attached bag falls regarding processing and feel out of the ordinary - velvet surface, thickly padded, top pocket for accessories (eg charger), handsome closure. Downright extravagant, it is then he prefers leaves the white charger cable multi-socket (Micro-USB 2, Micro-USB 3, Lightning, iPhone), an accessory that you own you, but doubts at home, because it in his pocket something applying (from a performance point of this cable is actually still okay, when comparing with my best cable it lets 80% of the current through Since I have significantly poorer charging cable -. without Multi connection).
His power is the power from willingly given 2.1A I have even slightly exceeded. It does not matter which USB port you choose, even the alleged 1 A output delivers maximum performance. If we use both ports at the same time and there is too much current drawn, a protection switches off the Power Bank.
With 10,400 mAh this equipment already one of the most luxuriant electricity suppliers, with which one not only in smartphones but also tablets, the battery power considerably this can completely recharge or renew. For the large capacity, the bank invites a bit slow even though with a maximum of 1 A and if it is even quite emptied. So here it is recommended timely charging, best night.
Not only, but particularly for design-oriented, I can recommend this power bank without hesitation.
