n this instructable I’ll show you how to build a detachable solar panel and battery charger for your backpack. This can power or charge all your gadgets (cell phone, mp3 player…) while on the road. HAMs can use it to power small QRP transmitters and receivers on a field day etc.
I was inspired by the excellent instructable “Rain or shine solar charger” by Blondietheblond, but wanted to avoid sewing, since I don’t have a machine. So this is the result.
