UltraFire 16340 Flashlight: Compact Powerhouse for Everyday Carry & Outdoor Adventures

A. Battery Versatility & High-Efficiency Charging

The 16340 lithium battery (16mm diameter, 34mm length) powers UltraFire flashlights with 3.7V rechargeable capacity or 3V non-rechargeable CR123A options. This dual compatibility ensures flexibility for users in emergencies or outdoor scenarios where charging isn’t feasible.

B. Compact Design with Rugged Performance

UltraFire’s 16340 flashlights prioritize pocket-sized portability (e.g., 54.5mm length, 51g weight) while maintaining IPX8 waterproofing for submersion up to 2 meters. Features like magnetic tail caps and rotatable belt clips enable hands-free use during repairs or outdoor activities. The UltraFire LED delivers 600–1200 lumens with adjustable focus, balancing flood and throw for tasks like hiking or emergency signaling.

Title

Q1: Can I use standard CR123A batteries in a 16340 flashlight?

A: Yes. UltraFire flashlights support both 16340 rechargeable and CR123A disposable batteries. However, CR123A provides lower brightness (e.g., 400 lumens vs. 700 lumens with 16340) but excels in extreme cold conditions.
