Just picked up a silva solar charger I from the bay for 20 quid, I thought it looked useful for charging some AA batteries while out camping (the batteries will be used to charge phone and gps using a battery usb charger) and will be fine to trickle charge over a couple of days. The fact that I can attatch it to my pack looks like a great idea.
Just wondered if anyone had any experiences with them?
