Product highlights

The Fenix E03R V2.0 is one of the smallest rechargeable flashlights you can put on a keyring — and one of the most surprising. Squeezed into a CNC-machined, full-metal body just 2 inches long, it throws a bright 500-lumen beam nearly 300 feet (90 meters), the kind of output you'd expect from something twice its size. A USB Type-C port and 400mAh battery keep it charged and ready, with an LED indicator so you always know where it stands, and an IP66 rating means splashes and dust are a non-issue.

This tiny rechargeable flashlight is tough, genuinely useful, and small enough to disappear until the exact moment you need it — which makes it as good a gift as it is a daily carry.

Performance Highlights

Output: High delivers 500 lumens with a 295 ft beam distance for close-quarters brightness.
Runtime: Eco stretches to 30 hours for extended everyday carry.
Extras: A dedicated Red mode (steady + flashing) and low-power Breathing Light preserve night vision.

Full mode-by-mode output, runtime, distance, and intensity figures are shown in the specifications chart above.

Key Features

White and red-light LEDs, plus a low-power breathing-light (constant-glow) mode
Single all-metal recessed switch cycles output and helps prevent accidental activation
Lockout function for safe storage and transport
Intelligent memory circuit recalls the last-used white light output level
All-metal A6061-T6 aluminum keychain body; 1 meter impact resistance, IP66 water resistance

Battery & Charging

Included: Built-in 400mAh Li-polymer battery (rechargeable)
Charging: USB Type-C; indicator glows red while charging and green when full
Note: Eco and Red modes remain usable while charging

Size & Weight

Dimensions: 2.07" x 1.02" x 0.51" (52.5 x 26 x 13 mm)

Best mini flashlight ever!

"Just bought a second one for myself, bought a third one as a gift. Perfect light, easy to carry, battery life is awesome. Very happy with these lights."

Bright - Handy Light - 3sec lock not enough

"Great light quality/brightness! Unfortunately 3sec lock is inadequate for pocket carry - turns on too easily meaning no power when needed. Received as a gift - will keep in car but unfortunately won't work for everyday carry-use."

— Dave (3/5)

Can't keep it off

"I was so enthused with this light I bought one for every member of my family. But they are virtually impossible to carry in your pocket without turning them on, so they are always dead when I go to use them."

— Frequent T. (1/5)

Handy Handy Handy

"Handiest flashlight I own. Carry it daily, from checking equipment in early morning hours to reading the menu in those dark ambiance restraunts. Like the different level of brightness depending on the situation."
