Solar battery
— the presence in the design of the lantern of a solar battery that generates current when light hits a photocell. Thus, the battery of the flashlight can be recharged by simply exposing it to the light. This allows you to do without sources of electricity for a long time and can be useful, for example, on a multi-day hike. In this case, it is not necessary to use direct sunlight: the photocell can also work in cloudy weather, and in some cases even under artificial light (although the efficiency of such charging will be lower).| solar battery | clear | Save List |
