How to prevent solar pannel DISCHARDING phone/devices ? Answered
I recently bought a 15W solar charger (without battery) to charge myphone on the go.
sadly i discovered that, if the sun is not bright enough, the pannel will actually DISCHARGE the phone battery
This is really a show stopper... I'm afraid it might damage the phone battery too.
So I was thinking, is there a way to prevent this? I guess a diode in line would be the best option, is it?
How about this:
Pannel ==/==> [male USB connector] + [diode] + [female USB] ==/==> USB cable => phone
Any ideas? hints?
