hello, due to my burden of access to a wall outlet I have invested in a solar and battery bank that I buck converted to 5volt. This step checked off my phone but I would like to tap my headlamp and radio into the juice (blackdiamond spot 3xaaa). does anyone know of a lighter and potentially cheaper version like this to charge the 3xaaa? http://www.amazon.com/gp/aw/d/B0107OK1RA/ref=ox_sc_act_image_1?ie=UTF8&psc=1&smid=A3M1K9LXDRB6PN I would like to get a tikka usb headlamp or a zebralight with the 18650 battery and charger, but I am going with the cheapest short term solution for now for I have ran out of aaa replacements Thank you!
