Scosche has dropped the price of its solar battery charger from $40 down to $25, plus you can get an extra 15% off by using promo code back2school until October 1st. The “sunVOLT” is a five-volt solar battery that holds a 500mAh charge and features little suction cups for use in the car.
There’s a mini-USB output with a mini-USB to female USB adapter included with the charger, so you can use it to juice up just about any USB-powered device. The above promo code works for other stuff on Scosche’s site, too, so go ahead and poke around. Loiter, even. It’s the internet.
