Solar ChumAlong: The Ultimate Solar Gadget Charger

We may earn a commission from links on this page.

Solar gadget chargers are not uncommon, but the ChumAlong is serious business. It's for people that like to get back to nature—without having to sacrifice modern conveniences.

The ChumAlong solar tracking system looks like it should be mounted on a Mars rover, but it is portable and intended for every day use. Plus, the 5W panel automatically follows the sun as it moves across the sky, so you should be able to power-up your gadgets with 30%-50% greater efficiency. On the downside, the unit itself will set you back $400—and that is without the rechargeable battery. [Scientifics Online via Red Ferret via SlipperyBrick]
