The TUNENGE S11-T keychain flashlight packs 500 lumens and a 278-foot beam into an ultra-slim 2.38 by 0.61 inch body, making it the perfect everyday carry light. Designed to clip onto your keys, slip into a pocket, or stash in a backpack, its always within reach for night runs, dog walks, power outages, and emergencies.

The ergonomic cylindrical body offers a comfortable grip, while single-button operation keeps things effortless-press and hold to cycle through Moonlight, Low, Medium, and High modes, or triple-click to activate strobe. A memory function recalls your last brightness setting each time you power it on.

Equipped with a 300mAh lithium battery and USB-C charging, it reaches a full charge in just 40 minutes and delivers up to 15 hours of runtime on Low, with a built-in indicator to monitor charging progress. A magnetic tail cap lets you attach it securely to metal surfaces for hands-free lighting during repairs, inspections, or automotive tasks.

With an IP66 waterproof rating and 1.5-meter drop resistance, this durable flashlight withstands rain and accidental falls, keeping you prepared for outdoor adventures, car maintenance, and everyday lighting needs.
