Hi I bought some days ago a "Patrick PowerBank 5200mAh" from a local shop and unfortunately the receipt is gone.
As obvious the bank doesn't work properly and if it's broken I'm f...ed.
I explain you what happens. The bank has a red led and a blue led, red led has to be on when the battery is low and when it is recharging, blue led has to be on when it's fully charged.
I have a Sony MT27i with a 5VDC output alimentator and when i plug the bank in it it never change red to blue led (also after 48h). In addition the phone recharge is very very slow with the bank: sometimes I can see battery drain when it's plugged.
There's any chance to make it work or is broken? I never tried to charge the bank from USB computer. Thanks.

Wall alimentator out: 5V/850mA
Power bank in: 5V/1A
Power bank out: 5V/1A
