Dynamo Flashlight
Batteryless Flashlights, Or Sometimes Known As Forever Flashlights
As the name suggests a Batteryless Flashlight works without any requirement of batteries. One can also call it as the forever flashlight. These types of flashlights need to be shaken back and forth for few seconds and they will give light for many minutes, sometimes even hours. The main features of these Batteryless Flashlights are
1) Never needs any batteries or bulbs
2) Now with magnet and tether strap
3) Compact and water resistant.
Perhaps the biggest feature is that these flashlights are rechargeable at any time.
· Magnetic Batteryless Flashlights
The product Magnetic Batteryless Flashlight is the newest technology among the batteryless flashlights. One just has to shake the flashlights for 60 seconds and you will get up to 2 hours of light from this magnetic batteryless flashlight. These flashlights have three super bright LEDs which emit bluish white light that helps us in viewing clearly in the dark.
There is a high field strength magnet inside these flashlights, that slides back and forth inside a coil of copper wire, as we shake it to generate electric power. This power then gets stored in a small capacitor. The stored energy in the capacitor then powers the high brightness white-light LEDs.
It is prudent to turn the switch off at the time of shaking the flashlights for charging. If the switch is not turned off then pulse with the power spikes coming from the coil can be seen in the LEDs. The operating switch of these batteryless flashlights is durable and intrinsically safe. These flashlights lights are very light in weight and are completely designed to be waterproof. They are also fully portable.
· Dynamo type Batteryless Flashlights
Another type of batteryless flashlights is of dynamo type. These were the oldest technology among the batteryless flashlights. These types of flashlights have little fold-out cranks and we need to wind on for a while so that we can use the light again. In Dynamo type flashlights, by winding the cranks for a few minutes, a sector gear starts to move causing a tiny pinion gear to spin which drives a PM dynamo. The dynamo generates electrical energy which is used to light the LEDs in the batteryless flashlights. For years there have been dynamo types flashlights around that the world those work by squeezing a lever handle. Dynamo type battery free flashlights are quite reliable than the ordinary battery lights.

The Batteryless flashlights are mainly used for emergency purpose. These flashlights sometimes come with built in FM radio. The main advantage of this Batteryless flashlight is that they are absolutely maintenance free. These flashlights can be stored for long periods of time without the worry of leaking batteries. In case of battery powered flashlights they often have their battery contacts loose
