The brainchild of a team of international designers under the umbrella of XD Design, the Window solar charger has an ABS plastic case with a PV panel surrounded by silicone pads capable of temporarily sticking to the glass of a window. On the base of the device are a full-size USB port and a mini-USB port for connecting portable devices in need of a clean energy battery boost. The charger itself contains a 1300 mAh Li-ion battery which is said to take around 13 hours of direct sunlight to reach full charge.
The Window solar charger outputs 5V/500mA via the included mini-USB cable, and has over-charge and over-heating protection built in. There's an LED charge indicator on the bottom edge which lights red when charging and green when the battery is full.
At EUR 49.95 (US$66), it's a little pricier than Quirky's Ray  USB solar charger for portable gadgets with built-in suction cup and kickstand, but it is a good deal more aesthetically-pleasing and with dimensions of just 11 x 11 x 1.75 cm (4.3 x 4.3 x 0.68 inches) and weighing 0.135 kg (4.76 ounces), it is rather more pocket-friendly.
