I think you have to make sure the output is the same V/A as your GPS device requires. My powerbank f*cked up the 800 I think because it turns out to have 2 outputs: 1x 5V/2A & 1x 5V/1A. Sorry I can't remember what output I used the 1st time I charged it during the ride (charged fast, no problems) or the 2nd time (no charging, lots of problems) and I don't want to repeat the experiment
