Make a solar battery charger using some dollar store path lights. Using 4 cheap dollar store garden lights you can make a very good solar AA or AAA battery charger for one or two batteries.
This is a simple solar garden light hack which gives you a decent solar charger worth about $20 if you were to buy it retail.
