Trust it or not, this torch don't need any battery! It just gets its energy from when you shake it. Simply shake it for 45 seconds, it will give you light for 5 minutes!
How does it work ? There is a magnet and a coil in the torch. When you shake it, the magnet moves toward the coil, and creates electricity. This is called the Faraday law. If you want more information, just look on the Internet!
