The digital display is great, but ...

I got me the PowerPack 5200 recently bought because I IMP1000 rarely more than half doing my twice as large / heavy NewTrent empty and the compact power pack should be quite sufficient. In addition, the digital display has lured me, because you can better assess whether still is enough juice in the Power Pack, or you should recharge.

In principle it works partly as it should. However, only with the short supplied cable. And since even at the 2.4A port. At the other port my smartphone (Nexus 5) attempts after a few minutes store debug the possible maximum current and detects the charger seemingly as overload and shut down. On 2.4A port charging works, however, prima ... with the supplied short cable.

Assuming a standard USB cable, see Android devices only "USB" as the power source and load with a greatly reduced current flow - namely only 500 mA. Apparently the PowerPack is thus optimized for iOS devices. With a suitable adapter you can also teach Android devices that it may draw more current. Thus at 2.4A port load my equipment as per power supply.

Overall, it does the job - just sad that almost all manufacturers still optimize their power packs only for Apple devices. Without adapter or special cable that is only partially useful for Android devices.
