UltraFire 18650 Flashlight: Power & Versatility Redefined

A. Durable Material & Ergonomic Design

Dual Battery Flexibility & High-Capacity Performance
The 18650 lithium battery (18mm diameter, 65mm length) offers 3.7V voltage and capacities ranging from 1800mAh to 3500mAh, balancing portability and extended runtime. These batteries support fast USB-C charging (2–3 hours) and compatibility with disposable CR123A cells for emergencies.

B. Adaptive Lighting & Rugged Engineering

Advanced UltraFire LEDs deliver up to 650–3000 lumens, with beam ranges exceeding 500 meters for tasks like cave exploration or search missions. Features like IPX8 waterproofing (submersion to 100m depth) and aircraft-grade aluminum alloy ensure durability in extreme conditions. Multi-functional designs include magnetic tail caps for hands-free use and zoomable optics for adjustable flood/throw lighting.

Frequently asked questions

Have questions? We’re here to help

Title

Q1: Can I use standard batteries if my 18650 runs out?

A: Yes. Most models support CR123A disposable batteries as backups, though brightness may drop by 30–40% compared to 18650 cells.

Q2: How long does charging take, and can I leave it in a hot car?

A: No. A 3500mAh 18650 charges fully in 4–5 hours at 1A current. Avoid prolonged exposure to temperatures above 140°F (60°C), which may degrade battery lifespan.
