Fenix E01 Keychain Light

The Fenix E01 is a mini LED flashlight with a negligible size and an impressive light output of up to 13 lumens. When it comes to durability, reliability, and bang-for-your-buck for a ridiculously small size, the E01 is the answer.

Engineered for Performance

Brighter than Expected

The Fenix E01 mini flashlight features a Nichia white GS LED that has a 100,000-hour lifespan, which makes it ready whenever needed. Now you don't have to fumble in the dark for your car keys or for the dook lock. The small-sized keychain light can also be used for reading in the dark. Additionally, one 1.5V AAA battery keeps this flashlight powered for up to 16.5 hours. We were surprised at the intense beam when we first turned it on, it is a wonder how Fenix does it!

Compact and Lightweight

Goes Where You Want

You are in the parking lot late at night after shopping for some AAA batteries, when you realized that you can get them on BatteryJunction for a way better price. You find your vehicle and take your car keys out to unlock the door, but keep missing the lock and scratching your fresh paint job with your keys. Oh no! Luckily, your E01 is there on your key ring. After turning it on, you finally find that door lock and with one swift motion, slide your key in and open your car door so you can get home safe. Weighing just half an ounce and measuring at under three inches, this light will go wherever you want, whether on-the-go in your pocket, on your keychain, or inside the kitchen drawer. Packing for camping trips is now a cinch as the E01 can easily slide into your backpack zipper pocket.

Rugged Design

One Tough Flashlight

Fenix made this light to handle bangs, bumps and drops. Constructed from aircraft grade aluminum and toughened ultra clear glass lens with an anti-reflective coating, included reverse polarity protection, and a sleek profile, the E01 will continue to operate no matter what you throw at it. Keep a strong grip on this baby as the body has a knurled texture for a solid grip. To operate the light, simply twist the bezel to get an instant 13 lumens, rather than pushing switches or buttons that stick out. Dropped your E01 in water? No worries, Fenix has you covered as this light is IPX-8 rated.

All That Most People Need from an EDC Light
October 24, 2016
For a few years the Fenix E01 in Olive was my EDC flashlight, always in my pocket on my EDC key ring along with a metal USB flash drive, an Inka Pen, and a mini-tube with meds. The E01 always served flawlessly, graciously dimming if the battery (ever) needed replacement.. Using an L92 Energizer AAA Lithium primary meant that I only once replaced the battery in all that time. For occasional use, the 13 Lumen 17 hour runtime (actually much more runtime with the L92 Lithium) specs are more than adequate - think most use is to look to see "where" or "what" for less than 30 seconds... 20 hours of 30 second uses means 2400 uses. Of course heavy users will want to use a 900mAH AAA NiMH for economy and keep a L92 Lithium AAA around as a spare. Recent E01's seem "brighter and whiter" than my old one, too, although there is still a blue tint. I enjoy giving these as Christmas gifts to family and friends.
The E01 has that reliable "twist switch" operation which also allows "press to light" when not quite twisted "on". The E01 (and the E05 mentioned below) also can be used as an area light in hanging from a 1 to 3 person tent's lantern loop, or a hammock or tarp's ridgeline. The cap from a ChapStick Brand balm tube snaps snuggly on the business end of the E01, and with a 9" length of thin guy line attached through its keyring, the E01 (or E05) can easily be suspended.
I mentioned "was my EDC"... I recently discovered the 2014 E05, and have switched to the E05 for its 3 levels of brightness while still keeping that reliable "twist switch" operation (I enjoy the "press to light" capability to quickly illuminate and even step through the modes). The E01, however, is even more reliable and quite adequate for the EDC needs of most of us.
  • Simple, reliable in electronic design and function with single mode and twist switch.
  • Adequate brightness for most "finding stuff" use.
  • Long, long run time due to this just adequate brightness, especially with an Energizer L92 AAA Lithium primary cell
  • Excellent durability, just long enough for easy one-handed operation.
  • Great value for the price.
  • A single mode "adequate" brightness doesn't meet everyone's needs in an EDC flashlight

Great EDC/keychain light
December 28, 2015
I've carried this little Fenix E01 on my keychain for years now. There's very little to complain about. It's not super bright; IIRC mine is the 9 lumen version. I see it's now rated at 13. It's not an awful lot of light but in really dark places you'd be surprised how well it works. The beam is pretty good with a clean, tight spot. Not much spill but with such a low powered light that's probably for the best. The anodizing is probably 50% gone on mine from years of being carried in my pocket, but aside from that it's held up very well. The big virtues of this light are the compact size, superb reliability/durability and outstanding runtime. I don't use mine for long stretches at a time but I've been running the same lithium AAA cell for almost three years! Despite drops and being banger around this light keeps on ticking.

The only thing I don't like is the tint- mine is really terrible, almost as purple as the body! Just angry blue. That's not ideal but in a light like this it's not a deal breaker. I wish it was a little bit brighter but if it was I wouldn't get years on a single battery.
  • - Very simple to use - extremely durable & reliable switch - stellar battery life - very compact
  • - Truly terrible tint, way too blue - Anodizing is pretty soft (however that's true of all colors but black, no matter who makes them)

I have purchased 5 or 6 of these got my use and gifts. I have one on my keys . In my hiking bags etc. with one extra AAA you have 40+ hrs of light. This one of my EDC items. I have added a mini ranger band to the lens ring (on/off) switch for easy one hand operation.
