Hi there,
I just bought a solar charger which has a build in 5 cells(6V) NiMH, when new there is some capacity on the cells so can charge my phone for a short while, but after hours of solar charging (without connect to the phone) I got 'not charging' error when I try to charge the phone, I got slightly over 6V at the plug without load, I wonder if this is too high ? the phone is ok I can charge with standard charger and USB, it is just the solar charger not working, I don't have the right tools to measure the charge current and voltage drop on load, but I suspect the N phone has too much sensitivity on the protection circuit blocking the charge, anyone has any idea ?
