Eton debuted four new solar and hand turbine powered accessories at CES, including two new solar-powered speaker systems and two naturally-powered charging accessories.

The RukusXL ($199) is a solar-powered, eight-driver Bluetooth speaker that provides a built-in lithium battery that can play music for up to 8 hours when out of sunlight, and recharges from direct sunlight in approximately 5 hours. A USB port allows a user to also charge a phone directly from the system.
The Rugged Rukus ($99) is a ruggedized portable Bluetooth speaker powered by either solar or an internal battery. Loops are provided for strapping onto a backpack and the speaker is also IPX4 splashproof.
BoostTurbine2000 ($60) is a rechargeable 2000 mAH USB battery pack with a hand turbine generator power generator, useful for emergencies. A micro-USB port is also provided for recharging the battery pack in a more traditional manner.
BoostSolar ($99) is a rugged rubberized backup battery pack, designed to be IPX4 splashproof, with a 4000mAh battery that can be recharged with solar power in 10 hours or over micro-USB in less time. Replaceable battery packs are sold as accessories.
