Meet the Power Gear: a hat that recharges your cell phone. It does a whole lot more though. You get micro flashlights. Its infrared lights are designed to block people from capturing your picture. The light can’t be seen by humans, so you won’t disturb people when you use it. The device is compatible with iPhone and Android smartphones.
The idea behind the Power Gear hat is pretty interesting. Many of us have battery extenders anyway. You can’t get more portable than this though. This product is currently active on Indiegogo.
