Solar chargers for smartphones are quite useful outdoors. They enable users to charger their gadgets anywhere. We have already covered many exciting solar chargers and cases for iPhone and iPad here. Booster happens to be a solar charger you can wear around your wrist. It can also be used as a power bank.
The idea here is to have a portable solar charger you can wear like a watch. It will be available to you anywhere you are as long as the sun comes up. A 900mAh battery is included. The Booster can be quite useful in emergency situations. Its shell is made of zinc alloy with the surface plating “Black Nickel.” It works for regular cell phone and smartphones. We would love to test it to see how it performs. The idea has some potential though.[via]
