Just like any other solar-powered devices, solar flashlights or torches are handheld lighting sources that have the ability to absorb the energy emitted by the sun and store it in its rechargeable batteries. These devices also use LEDs (Light-Emitting Diodes) lamps that can give useful levels of illumination up to 50 meters.

Deemed as innovative inventions, solar flashlights are similar to regular flashlights, which have various designs. But instead of batteries or being dependent on charging through a wall outlet, there is a small solar array of photovoltaic cells embedded in the handle, through which the flashlight is easily charged. These devices also use LED bulb.

It is a given fact that not all people in the world have access to electricity. As a matter of fact, one major reason solar-powered flashlights were invented was to deliver a stable source of light in areas where there’s erratic or no power supply. These devices were not only useful to outdoor adventures but also emergency situations. That is why they are also considered essential survival tools.
