Today I have the Fenix E02R keychain flashlight, a two mode flashlight with twisty user interface, and micro-USB charging. Read on for testing!
Official Specs and Features of the Fenix E02R Keychain Flashlight
Fenix E02R Keychain Flashlight Versions
There are three body colors, but just one version of the Fenix E02R Keychain flashlight.
The Fenix E02R Keychain flashlight is going for $23.95, and it’s available at Fenix-Store.com right now!
This is a predictable little keychain light, with fairly standard features, and seems reliable.

Package and Manual
Build Quality and Disassembly
The pictures might not tell the story immediately, but this is a tiny little light.
Here’s a top down view:
The Fenix E02R keychain flashlight unscrews to the point you see below. I could make it go no further, and I persuaded it not-so-gently. Maybe there are some press fit pieces, or some loctite, but I couldn’t get these parts to part.
So no real disassembly photos…. sorry!
Size and Comps
Head Diameter: .59″
Body Diameter: .55″
Weight: .52 oz (Excluding Battery)
Funny that Fenix would list the weight without battery. This just leads me to believe I never figured out how to remove the cell…..
If a light will headstand, I’ll show it here (usually the third photo). If a light will tailstand, I’ll show that here, too (usually the fourth photo).
Here’s the test light with the venerable Convoy S2+. Mine’s a custom “baked” edition Nichia 219b triple. A very nice 18650 light.
And here’s the light beside my custom engraved TorchLAB BOSS 35, an 18350 light. I reviewed the aluminum version of that light in both 35 and 70 format.
A few other small lights, which are all 10180 powered. I presume this Fenix E02R Keychain flashlight is too, but I don’t think Fenix states that.
Retention and Carry
There’s not much in the way of carry options for the Fenix E02R Keychain flashlight. The split ring can attach through this tailcap.
There is no pocket clip or magnet or otherwise.
Power and Runtime
As stated above, I was unable to disassemble this light, to see what cell is inside. Almost certainly it’s a single 10180 cell though. It’d be nice for this to be user replaceable, but that doesn’t seem like an option.
Here are runtimes for both modes.
Output on High drops dramatically, and in both runtimes, the output trails off without seeming to offer low voltage protection at all.
With the built in battery, you’d expect on-board charging – and you’ll get it. It’s in the form of a micro-USB port, which is revealed by unscrewing the body.
An appropriate cable is included – USB to micro-USB.
There’s also a charge indicator just beside the charge port. When charging, the translucent dot is red. When charge is complete, the dot turns to…. greenish – not quite green, but decidedly not red, too.
Charging is consistently around 0.1A, which should be fine for the built in battery. This does take a while, at around 3 hours in my tests, though.
Modes and Currents
|Mode||Mode Claimed Output (lm)||Claimed Runtime||Measured Lumens||Tailcap Amps|
Pulse Width Modulation
No pwm is to be seen on either mode.
For reference, here’s a baseline shot, with all the room lights off and almost nothing hitting the sensor. And here’s the worst PWM light I have ever owned. Also one of the very first lights I ordered directly from China!
User Interface and Operation
The Fenix E02R keychain flashlight is a twist operated light. But it’s unusual (ish) in that it’s a progressive twisty.
It’s possible to twist the light with one hand, though the small size does complicate that.
Here’s a UI table!
LED and Beam
The product page says the Fenix E02R keychain flashlight has a Cree XP-G2 emitter. I believe it’s cool, and the photos below support this.
Fenix uses a very short TIR in the light, too.
These beamshots are always with the following settings: f8, ISO100, 0.3s shutter, and manual 5000K exposure.
Tint vs BLF-348 (KillzoneFlashlights.com 219b version) (affiliate link)
Test light is on the left!
I compare everything to the KillzoneFlashlights.com 219b BLF-348, because it’s inexpensive and has the best tint!
What I like
- Small size
