problem when charging via powerbank
« on: November 07, 2015, 12:49:16 PM »
Hi,
I try to charge my Revolution via powerbank and it doesn't work. The bank (VARTA Indestructible Powerpack 6000) have 2 outputs, 1A and 2.5A. If I connect the phone with an output, the bank run some seconds and then disable by itself. I tried the USB cables from the bank, the phone and also from an other phone, but nothing works. I think, the bank is okay, I can charge other phones, e.g. S4 mini. Have anyone an idea?

regards, Frank

I don't really have solution about that but I also notice that my revolution phone doesn't charge very well when I plug it on my laptop with a USB cable different from the one provided by Geeksphone.
I think USB protocol is quite complex and not all cables or interfaces implement all the specifications about charging.
