Fenix E01 V2.0 Blue AAA Keychain Flashlight 100 Lumens EDC Pocket Torch

The Fenix E01 V2.0 is a pocket-sized powerhouse delivering 100 lumens from a single AAA battery. Its ultra-thin optical lens produces a soft, balanced beam reaching 115 feet, perfect for everyday carry. Measuring just 2.6 inches long with a compact 0.5-inch diameter, this lightweight flashlight won't weigh you down. Three adjustable brightness levels offer flexibility—simply twist the head to switch modes. Built rugged with an IP68 rating, it withstands dust and water immersion, ensuring durability in any condition. Whether for work, camping, or daily tasks, the E01 V2.0 combines portability with reliable performance in an EDC essential that fits anywhere.

Fenix E01 V2.0 - 100-Lumen AAA Keychain Flashlight Built for Real Carry

The Fenix E01 V2.0 is the light you actually keep on you. It runs on one standard AAA cell, throws 100 lumens out to 115 feet (35 meters), and measures just 2.62 inches with a 0.59-inch head - small enough to disappear on a keychain, strong enough to work when the power is out. Tactical and EDC flashlights at EDCMALL are chosen for the same reason this one survives year after year: it does one job without excuses.

The head rotates for mode selection, so there is no tail switch to fumble with gloves on and no parasitic drain when it rides in a pocket. A Luminus SST20 Cold White LED rated at 50,000 hours sits behind an ultra-thin polycarbonate lens that produces a soft, balanced beam instead of a harsh hotspot. The all-metal CNC-machined body wears premium Type HAIII hard-anodized finish, and the IP68 rating means dust ingress and water immersion are non-issues.

LED, Output and Runtime

• Luminus SST20 Cold White LED - 50,000-hour rated emitter with a 6500K color temperature and a clean, even beam profile.
• 100 max lumens on high, with three twist-selectable output levels for close-range work, walking and signaling.
• 115 ft / 35 m beam distance - enough reach to check a treeline, a stairwell or the far end of a parking garage.
• Up to 25 hours max runtime from a single AAA battery, and the cell is included in the box.
• Ultra-thin optical lens - polycarbonate, impact-tolerant, tuned for a soft and balanced spill instead of a tunnel hotspot.
• Twist-head mode switching - one-handed operation, no click switch to wear out or accidentally trigger in a pocket.
• IP68 dust and water resistance - survives full immersion; rain, mud and dropped-in-a-puddle incidents are covered.
• 0.46 oz (13 g) without battery - effectively weightless on a keyring or lanyard.

Where the Fenix E01 V2.0 Earns Its Place

• Keychain and pocket carry - 2.62 inches long, 0.55-inch body diameter; it rides next to keys without becoming a brick.
• Blackout and power-outage duty - a 25-hour runtime and a standard AAA cell make it a genuine emergency light, not a toy.
• Work and inspection - 115 feet of throw for checking panels, crawlspaces, engine bays and cabinets.
• Camping and hiking - twist activation works with gloves, and the IP68 body shrugs off rain and stream crossings.
• Everyday task lighting - enough spill to change a tire, read a map or find a dropped screw in a dim room.

Frequently Asked Questions

How many lumens does the Fenix E01 V2.0 put out?
A maximum of 100 lumens. Three output levels are available, changed by rotating the head rather than pressing a switch.

What battery does it use, and is one included?
One AAA battery. A Pairdeer AAA cell ships in the box, along with a key chain. Alkaline or NiMH rechargeables both work.

How long does it run on high?
Up to 25 hours maximum runtime depending on the level selected and the battery used. Because it takes a standard AAA, you can restock anywhere.

Is the Fenix E01 V2.0 waterproof?
Yes - IP68. That covers dust ingress and water immersion, so rain, splashes and a dropped-in-a-puddle moment will not kill it. It is not intended for pressurized diving.

Can I use it one-handed?
Yes. The rotating head is designed for one-handed operation, which is why it works well with gloves on.

Does it have a pocket clip?
No. It is built as a keychain light - it includes a key chain, and its 0.46 oz weight and compact size suit a keyring, lanyard or zip pull.

Glossary of Terms

IP68
An ingress protection rating. The first digit (6) means dust-tight; the second (8) means the enclosure survives continuous immersion in water under the conditions the manufacturer specifies.

Luminus SST20
A compact, high-efficacy LED emitter known for consistent tint and a long rated life. Common in small EDC and keychain lights.

HAIII Hard Anodizing
A Type III anodized coating, the thickest and hardest anodizing class commonly used on aluminum flashlight bodies. It resists abrasion and minor impact far better than cosmetic Type II finishes.

Color Temperature (6500K)
How warm or cool the beam looks. 6500K is cool white - slightly blue-tinted, high apparent brightness, good for detail and distance work.

Beam Distance (ANSI)
The rated throw measured to 0.25 lux. 115 feet (35 meters) is how far the beam still produces usable light, not how far you can see a glow.

Tail vs. Twist Switch
A twist switch rotates the head to complete the circuit. It has no mechanical click switch to wear out and cannot be accidentally activated in a pocket.

Who Should Buy the Fenix E01 V2.0

Who should buy it

• Anyone who wants a light that is always physically on them, not in a drawer
• Preparedness-minded buyers who value a 25-hour runtime and a standard AAA cell
• Technicians, mechanics and inspectors who need reach in tight, dirty spaces
• Campers and hikers who want a rain-proof backup light that weighs nothing
• Buyers who want genuine Fenix build quality at a sub-$15 price point

Who should skip it

• Anyone who needs a tactical momentary-on tail switch for defensive use - this is a twist-head utility light
• Users who need 500+ lumens, long throw or USB-C recharging - step up in the Fenix range instead
• Buyers who want a neutral or warm tint; the SST20 here is 6500K cool white
• Anyone expecting a pocket clip or a magnetic tail - it has neither
• Hands that find small twist heads fiddly; the body is only 0.55 in across

Care & Maintenance

1. Wipe the body and lens with a soft dry cloth after heavy use; grit on the lens costs you beam quality.
2. Clean the head threads periodically with a lint-free cloth, then apply a thin film of silicone or dielectric grease so the twist action stays smooth.
3. Inspect and replace the head O-ring if it looks dry, cracked or flattened - the O-ring, not the metal, is what makes the IP68 rating work.
4. Do not overtighten the head; snug is enough, and forcing it crushes the O-ring.
5. Remove the battery for long-term storage to prevent alkaline leakage from destroying the driver.
6. Avoid mixing old and new cells, or alkaline and NiMH cells, in the same light.
7. Rinse with fresh water after saltwater or heavy sweat exposure, then dry fully before sealing it back up.
8. Do not use solvents, acetone or abrasive polishes on the HAIII anodized finish.
9. Store it with the head backed off slightly so the light cannot drain the cell while it sits in a bag.
