Art meets Green Technology. The Solar SunTree phone charger has a bamboo stem that blends into the room like a piece of furniture. It holds 9 solar panels, charges most USB powered devices and gives an output of approx 5V. A creative and fun design, it definitely stands a world apart than the conventional solar chargers currently on the market. This is reflected in the price, which stands at a whopping £92 (not including shipping), i kid you not. Okay so it's fairly steep, but maybe it could work as a retro wedding present/piece of arty furniture that also has a practical function for that eco warrior friend. Made by XD Design and available from amazon uk. Or see an alternative, cheaper iphone solar charger $29.
