This amazing flashlight comes with a single LED bulb which charges automatically when shaken. It uses Faraday's law of induction, so it works every time. It is waterproof, floats and is visible up to one mile.

30 seconds of quick shaking will produce enough electricity to provide light for up to 4-5 minutes continuous use. An excellent choice in emergency kits, in the home, vehicle, boat, fishing, camping, hiking etc. Great for kids too, no more wasted batteries, you provide the power. You may see similar smaller less powerful advertised elsewhere. This is the more powerful model measuring 180mm by 40mm.
