Wind up flashlights are conveyable devices that are used for dealing with crisis situations such as power outrages and blackouts caused due to hurricanes, tornadoes, lightning, flooding, and blown out road transformers. They are designed for rough use and can withstand shocks and vibrations that may occur while using them in emergencies.
Wind up flashlights are carefully good than rechargeable battery powered flashlights as they can be used as and when needed and do not depend on internal or external battery source. Some wind up flashlights have electric outlet ports that can be used for charging an Am/Fm radio to keep users modernize on the latest civil and natural emergencies occurring in the local area that might work on power supply. It can also be used to charge mobile phones.
The basic mechanism that provides power to wind up flashlights is similar to an electric generator that converts mechanical or kinetic vigor into electrical energy. In wind up flashlights, users just need to turn a lever provided on the side or back of the flashlight that winds up the metallic coil present in the flashlight. The coil is related to a small electric generation unit that converts the mechanical vigor of the wound up coil into electrical energy.
The number of times users have to rotate the lever depends on the type of generator and coil used inside the flashlight. On an average, wind up flashlights can be used for six to eight minutes on a particular charge depending on the wattage of bulb used in the flashlight.
Wind up flashlights are the most environmentally kindly devices available, as they do not use batteries that eventually have to be dumped, leading to environmental pollution. The only drawback of wind up flashlights is that the metallic coil may wear out due to constant coiling and uncoiling process and may need replacement.
