Hand-pressing Flashlight

by Joseph

There have been quite a few electrical gadgets that I have encountered over the years, but in recent history, I have been impressed by a cool electrical gadget called the Hand-pressing Flashlight. I am not sure about the price of this gadget as it has been given to me as a gift sample by an outfit company doing promotions for its innovative product.

Flashlights are quite useful in my country where power outages are a normal occurrence, and this Hand-pressing Flashlight really takes the cake, so to speak. Unlike the conventional flashlight, the Hand-pressing Flashlight surprisingly uses no batteries and no light bulbs!

It uses power stored from energy generated by manual hand grips repetitively done over a short period of time. The renown principle of the dynamo is utilized here - an electrical generator only uses the energy from hand grips, and it has a power storing device in it to preserve the generated energy. Instead of the usual light bulbs, it features three light-emitting diodes (LEDs) illuminating the surrounding much like an ordinary flashlight.

This product combines science and technology, providing illumination by "pumping" the hand in proper rhythm. The Hand-pressing Flashlight has a host of advantages, specifically it needs no batteries or external power source, causes no environmental pollution, emits low noise and poses no health risk, virtually providing light in perpetuity. Besides that, while generating power, you get to exercise your palm, arm and shoulder for better blood circulation.

This gadget has practically no disadvantage, except maybe the extra effort of manually generating power for its dynamo, and perhaps the shorter duration of its lighting power compared to the conventional flashlights using batteries.

Editor's note:

Here is an example of a hand-pressing flashlight that you can buy from Amazon. It comes also with an emergency whistle.
