Even though we’ve never reviewed them here (what’s wrong with us?) we actually own and use both the Powermonkey eXplorer and the Solio Magnesium Edition Solar Charger and find both of them quite satisfactory. However either of these solar chargers run upwards of $100 to own. ThinkGeek has the budget conscious in mind with the Pico Freeloader Solar Charger, a compact and lightweight wonder that according to the specs provides power of 35 hours on mobile phone, 14 hours on iPod, or 1.5 hours on GPS on a single ten hour charge. What’s particularly nice about the Pico is that you can recharge its internal lithium ion via USB in case of eternal winter (no sun). Oh, did we mention it’s only $39?
