15 Best Keychain Flashlights

15 Best Keychain Flashlights

For most guys, your pocket everyday carry consists of a wallet, knife, keychain, and probably a bunch of screwed up receipts. But none of those things will light up the way as night draws in. Sure a full-sized flashlight is going to illuminate a wider area but when size matters a compact light source is a must have EDC item.

What keychain flashlights lack in power compared to their full-size counterparts they make up for in portability. A well-engineered pocket light will stand up to extreme weather conditions, have various basic settings, a long battery life, and powerful LED bulb, and still be compact enough to slide onto your keychain or slip into your pocket without hassle.

The Best Keychain Flashlights

As LED technology gets more sophisticated, the range of keychain flashlights grows. Having so much choice can be a real headache when trying to choose the best power source. So we’ve done the hard work for you with our list of the best keychain flashlights on the market, ready to help you out in the dark.

Foursevens Atom AL Flashlight

Foursevens Atom AL Flashlight

Featuring a simple two-mode interface, extended run times (up to 40 hours), and a neodymium magnet embedded in the tail the Atom can be attached to any ferrous surface. With IPX8 water resistance and a CREE XP-G2 LED emitting either six lumens on low or 110 lumens on high the AL is a very accomplished keychain flashlight.
