The Solar Power Dock — from Netherlands-based manufacturer A-solar and solar tech company Intivation — was unveiled earlier this week at the Mobile World Congress trade show in Barcelona. It charges iOS devices such as the iPhone and iPad with a little help from the sun and is small enough to fit in your pocket.

With a durable built-in Solar Panel Charger with 45Wh Solar Battery for Laptops Cell Phones battery, a small solar panel and strong rubber-finished casing, the Solar Power battery Dock can keep devices running when you’re far away from an outlet. The price: $105.

The internal battery stores an impressive 6,000 milliamp-hours (mAh) at full capacity, a bit more than your average solar charger, like the Solio. After 12 to 16 hours in the sun, the Dock will have a full charge, able to juice up your iPhone with about four hours of talk time. It can still soak up energy on cloudy days, too. However, the Solar Power Dock has only enough capacity to charge the iPad up to 60%

More of an Android person? The Solar Power Dock also features an integrated USB output, so it can be used for charging other kinds of phones besides iPhones.
