What To Look For When Buying the Best Keychain Flashlight

If you are going to have a flashlight on your keychain, you already know that a flashlight that is with you all of the time is an invaluable tool. The best keychain flashlight is a relative term – it really matters where you keep your keys and how much room you think you can take up with a flashlight. Since keychain flashlights are usually really small, they are not as powerful as some other every day carry (EDC) flashlights. With that said most flashlight manufacturers produce some sort of a keychain light.

The two main varieties that you will find are the super small micro lights that run off of a watch battery and lights that run on a single AAA battery. There are keychain flashlights that use other battery types like AA or CR123A, but they get a little wider than most want to keep on their keys. A keychain flashlight needs to be very durable and reliable. If we have the added luxury of high lumens in a flashlight, it is nice, but the most important things are size, durability and reliability.

AAA Flashlights

Flashlights that use AAA batteries are much bigger than the button cell flashlights above, but they have a much higher output. Since you have a higher output you are going to go through batteries much faster. If you want to invest a little into having the best rechargeable batteries the Eneloop AAA Ni-MH fit the bill. Our favorite charger for the Eneloops is the La Crosse BC-700 since it easy to use, high quality, and works for both AA and AAA batteries. For non-rechargeable batteries the Energizer L92 Lithium batteries are superior, they are lithium and not alkaline so they have more charge and a longer shelf life.

Best AAA Flashlight

Maratac Copper Rev4

Maratac AAA LED Flashlight - 3 Mode Med/Lo/Hi - Includes Glow Diffuser/Lantern - Military Spec - Waterproof, Dust Proof, Weather Proof - Everyday Carry (EDC) (Copper)

As part of the Executive Series the Maratac Copper Rev 4 offers the long awaited medium/low/high settings order that thousands of users have requested. Most users find that they often use the light on the medium setting rather than high or low, so it makes more sense to have the light power up in the most used mode. The body of the light is manufactured from an ultra conductive C360 Free Machining Brass. The light is packed within foil packs to help protect and preserve the hand finished light.

With the Maratac Copper Rev 4 users have the option of the three brightness levels with the highest setting offering 15 lumens and the lowest setting 1.5 lumens.  Using a Nichia 219C LED with a 50,000 hour life span, the Maratac Copper Rev 4 offers the newest and brightest emitter available.

The AR coated lens is paired with an aluminum alloy orange peel reflector to provide a smooth, steady beam of light. Powered by an ordinary AAA battery the light can run from 55 hours on its lowest setting. As ordinary alkaline batteries have a higher risk of leaking the manufacturer strongly recommends using a rechargeable battery instead. A great light that would be a great survival flashlight option.

Pros:

  • Glow in the dark features
  • Multiple brightness levels
  • Comes with pocket clip

Cons:

  • Finish peels after a few months
