One of the biggest complaints mobile gadgetizers have is battery life, or rather, the lack thereof. Enter - the iSun Sport solar battery charger. Just plug your gadget in using one of the various cords included with the unit, flip it open facing the sun and you’ll be juiced up in no time. From the product specs:

Whether you need to charge your cell phone or PDA while on a business trip, charge your GPS while trekking through the wilderness or run your MP3 player at the beach, the iSun® can make it happen. The iSun® is capable of running most small electronics requiring less than 2 watts of power. For electronics requiring more than 2 watts, multiple iSuns® can be connected together for additional power.

But it would suck to be you if you needed to recharge at night or on a cloudy day.
