What is a Rechargeable Flashlight?

A rechargeable flashlight is a portable device meant to provide emergency or temporary light in a location for a certain purpose. The energy from the flashlight comes from an onboard battery pack which is capable of being recharged or from an onboard generator powered by motion. A rechargeable flashlight is most useful in situations where continued use of a traditional flashlight would cause a significant expense in batteries. Most rechargeable flashlights have an onboard battery pack. This battery pack can last anywhere from several hours to dozens of hours, depending on the lamp source and its required output. In most cases, getting a few hours of use out of a battery is all that is required. In some cases, a rechargeable flashlight may come with a docking station. This makes it convenient to recharge. When not in use, the most logical spot to store the flashlight is in its docking station. That way, when it is needed again, it is ready and fully charged. The docking station usually

Only two extra points: Some rechargeable flashlights have a solar panel on the side. When the flashlight is left in the sun for a number of hours, its is charged sufficiently to give an output of about 25% to 50% of the “charge-time.” A solar panel can also be purchased as a separate item. Finally, a flashlight known as a “Shake flashlight” is available on the market in both large and small sizes. It has a coil of wire and a magnet that moves inside the coil from one end to the other. By shaking the torch to make the magnet move back and forth, a voltage is generated and this is stored in a “Super Cap” ( a bit like a small battery). The principle of operation has been attributed to Faraday, one of the early experimenters (pioneers) in electrical phenomena. Colin Mitchell TALKING ELECTRONICS .com talking@tpg.com.
