If you’ve ever needed power on the go but don’t want to lug a portable battery charger around, a new Kickstarter project could provide the answer. The bright minds behind Startup EnergyBionic have slapped a solar charger on a wristband to give you sun-powered juice for your phone. Called Carbon, the wearable charger will cost $95 if you back the project now. The device is estimated to ship in August, if the project is funded by March 31.

Don’t be fooled into thinking this functions as a watch. Carbon is simply a solar cell built into what looks like a watch face. A charging port, LED indicator and button line the edges. The multi-color LED light flashes to indicate battery charge level, charging status and can even act as a mini flashlight or safety strobe when you need it. Carbon is also dust and water resistant.

Charging is activated by pushing the button below the connector, and you access the port by unscrewing a hinged cover. Each Carbon comes with a set of mini cables with a 2.5mm jack on one end and a iPhone 4/4S, Lightning (iPhone 5/5s), microUSB and USB on the other.

Each cable is just 4 inches long, so you ‘ll have to keep your phone close as you charge it. A 650-mAh lithium polymer battery should offer a charge of approximately 1 Amp, 5 volts and 5 watts to your devices. According to EnergyBionics, this means it will take Carbon about 25 minutes to put out a full charge.
