Key Chain Solar Charger

The key Chain solar charger is meant to slow down the drain of your battery, but if you’re patient enough, you might be able to charge it, although I guess that it would take a few days for a full charge (if the phone is turned off).

The manufacturer had some kind of marketing gimmick around “being green”, but that’s crap: more carbon will be generated by creating, shipping and disposing of this device than it will ever save. Price: $22
