Here is another device for the campers who often need a flashlight to light the way. While we all know that most flashlights are battery-powered, here is one the thrives on solar power all thanks to the presence and use of polymer solar cells.
The mini solar powered flashlight comes from Riso DTU, a small and lightweight flashlight that can be easily charged once power goes low. Though it does come in an unconventional shape, the important thing is that it can be used to light the way.
Actually, the flashlight comes close to being similar to the shape of a credit card. The solar cells will be behind the recharging of the built-in lithium ion polymer battery which will juice up the LED located at the top. The compact flashlight is a concept for now.
