Since the charging performance was bemänglet I once measured it:
1100mAH battery was in 1: 50h loaded, makes me 600mA charge current if a device is connected.
Contrary to Vorrezensenten I find the LED sense.
This is a confirmation that the device is working, then you can quickly isolate the fault in case of problems ...
But whether the device is really of Ansmann, I put something in doubt.
In the pack is about all thick and wide HyCell plan.
Only very small is somewhere Ansmann as a contact address on it.
This may for example mean Ansmann executes only the complaints for HyCell.
It could also be that HyCell is the favorable sub company of Ansmann.
Who knows ..
Because of the failure to comply with the promise of charging current I subtract 1 star.
Since I had been expecting but by an earlier review, I am fully satisfied on.
