The Power Bank invites my IceFox F9 correct only after I had to find its own charging cable to and buy

The unit was placed in an obvious violently torn cardboard box in a plastic cup, without protective film or transport protection and without instructions. The enclosed cable had signs of wear. Using the supplied (cheap) cable charging takes longer than a lot with my Smartphoneladeset. So no trace of Supercharger. Since all the plugs were delivered twice, but only 1 used charging cable, I'm assuming that one is missing. The Power Bank lies down as the HP described, but only load with a quality cable, and seems to be as far as OK. Using the supplied cable, charging cheap, however, would take an eternity.
Following the advice of an acquaintance to use only the cables quality, my smartphone at 1A load USBausgang lies with 1A, however, stopped the charging process at 60 percent and turned itself off. Whether this is a device error, I do not know, in any case the device does not deliver what it promises, with the supplied cheap cable it invites namely 100%, but it takes far too long as the output under 5V and 500 mAh is,
The Capacity is according to print on the back at 16800 mAh, not as described on the HP at 15,000 what I feel is positive and therefore awarded 3 points. Since only Apple plugs are beigelgt, it might work correctly with Apple devices, but I do not know, because I have to charge other devices.
I would have, therefore, a suitable charge lead expected, which meets the performance requirements of the Power Bank in every respect.

PS: now use a pure charging cable and thus work loading and unloading the battery properly. The supplied cable set is the largest scrap and if you use this, you think the battery is broken, It is only on cable.
PS: after 4 months and lediglichem both pleasure the first USBstecker is already inoperable.
