Fenix E03R V2.0 Blue Rechargeable Keychain Flashlight

The Fenix E03R V2.0 is a compact rechargeable LED flashlight designed to provide versatile lighting without taking up much space on your keychain. Despite measuring just 52.5 mm long, it produces up to 500 lumens and reaches a maximum beam distance of 90 meters. Four white-light brightness levels make it useful for everyday tasks, while dedicated red-light and flashing modes add options for low-light visibility and signaling.

The blue E03R V2.0 features a built-in 400mAh lithium-polymer battery that recharges through a USB Type-C port. A recessed side switch controls the lighting modes and helps reduce accidental activation, while an electronic lockout provides additional protection during storage or transport. The CNC-machined aluminum body features a hard-anodized finish and IP66-rated dust and water resistance. Weighing just 30 grams with the battery, this miniature flashlight is a practical choice for everyday carry, travel, and emergency kits.

Fenix E03R V2.0 Flashlight Specifications

Brightness Levels and Runtime

The E03R V2.0 provides four white-light brightness levels, two red-light modes, and a decorative red/green pulse light.

*High-mode runtime includes periods of reduced output as the flashlight's thermal protection manages temperature. Actual performance varies with operating conditions.

Red Light and Red/Green Pulse Light

In addition to its four white-light settings, the E03R V2.0 includes a steady red light and a red flashing mode. These provide alternatives to bright white illumination for close-range visibility and signaling. The separate red/green pulse light adds a decorative lighting option that can also help make the flashlight easier to locate in low-light conditions.

USB-C Charging and Battery Monitoring

The built-in 400mAh lithium-polymer battery recharges through a USB Type-C port, with an approximate full charging time of two hours. A battery-level indicator helps you check remaining power, while the low-voltage warning signals when recharging is needed. The battery is integrated into the flashlight and is not user-replaceable.

Simple Operation and Electronic Lockout

The recessed side switch controls the E03R V2.0's lighting modes. Press and hold for approximately half a second to turn on the white light, then click to cycle through Eco, Low, Medium, and High. Press and hold for approximately 1.2 seconds to access the red light. With the flashlight off and unlocked, double-click to activate the red/green pulse light. An electronic lockout helps prevent accidental activation in a pocket or bag.

Compact Aluminum Construction

The E03R V2.0 features a CNC-machined aluminum body with a premium HAIII hard-anodized finish for abrasion resistance. Its IP66 rating provides protection against dust and powerful water jets, making it suitable for rain and wet conditions when the charging-port cover is properly closed. Unlike IP68-rated flashlights, the E03R V2.0 is not rated for submersion. Its compact size and included key ring make it easy to carry every day.
