- Compact, affordable flashlight with a lanyard for easy carrying. - Power source and storage: uses hand-pressure automatic power generation with a built-in micro-power generation device that uses the triboelectric principle. Unlike flashlights that rely on disposable dry batteries, this unit stores energy for later use. - How it works: a few squeezes on the lower hand-held grip generate electricity, which is stored in the built-in storage. The LEDs light when you switch to the stored power. - Lighting: features two ultra-high-brightness white LEDs for high visibility. - Operation: a top switch controls access to the stored power; once charged, the flashlight can illuminate for a period without needing new batteries. - Use and reliability: suitable for both regular use and occasional use. Regular use saves money by avoiding battery purchases and electrical prep; stored power provides lighting when needed. - Use scenarios: home emergency power outages, camping or hiking trips, and travel or everyday carry in a bag or car for reliable light without disposable batteries.
