Trinity portable wind turbine ... 30 cm in height, 15 watt generator, 15,000-mAh lithium-polymer battery pack and two USB ports.
The plastic-bodied Trinity is carried as a 12-inch (30.5-cm) cylinder when not in use. When you want to juice it up, you pull out the turbine's three aluminum legs, and prop it up to catch the wind. The legs can be laid flat to form a pedestal, or partially extended to form a tripod base. And yes, it is waterproof (rated to IPX6), should the wind be accompanied by rain.
As the blades turn, they spin an internal 15-watt generator that in turn charges a 15,000-mAh lithium-polymer battery pack. Using one of two USB ports on the bottom of the unit, you can then plug in your phone (or other device) and charge it. According to Skajaquoda, the Minnesota-based company that's developing the Trinity, one full charge of the battery should allow for four to six phone charges – you can also forgo the battery, and charge your phone directly from the generator.
