A battery-flashlight is a common possession for most of us, who we live off-grid – ie go out of house to the woods, in the garage for collecting a thing in the dark, or go out in a car. But batteries are expensive, are usually dead when you need them! And on the lines of the environmental concerns, usually transform into landfills, although they are supposed to be recycled.
You must be thinking – ‘then, what can be done?!’ True, it’s a solution to an extent, if you are thinking of the rechargeable route. But, now here is a much better solution. It’s a bright LED flashlight that needs no batteries. It just needs an occasional shake. It can claim to be one of the best inventions ever. It’s not only that, it can be of cheaper than you’d pay for batteries for a year. Thanks Steve for this nice piece of information.
