Trending: Fenix E01 V2.0 Keychain Flashlight

The Fenix E01 V2.0 comes ready to use with an AAA alkaline battery in the box, and it’s also compatible with rechargeable Ni-MH batteries, giving you a higher output and sustainable reusability. It powers the light’s Cree XP-G2 S3 LED to a maximum 100 lumens with up to 114 feet of throw. It’s able to hold this for 50 minutes off a topped off battery, and gives you a good burst of light for everyday use. From off, tightening the head gives you a 5-lumen Low mode with a 25-hour runtime, while a quick twist off and on again accesses the 25-lumen Medium good for just under 5 hours. One final twist ends up at the 100-lumen High. The V2.0 has come a long way from the 13-lumen, single output of the original.

The E01 V2.0’s 2.62"-long CNC-machined aluminum body comes shorter than its predecessor, boasting IP68-rated protection that allows it 6.5 feet of submersion for 30 minutes—more than adequate for the splashes and accidental dunks of a keychain light. It’s also passed a 1.5-meter drop test to ensure continued use and operation even with the worst tumbles with your keys. To that end, a wider and more robust loop has been built into the tail end of the light, making it easy to slip the included split ring through. As usual, a spare o-ring is included to help maintain the light’s waterproof rating over time.
