Best Keychain Flashlights 2024 [7 LED Keyring Torch Picks]

(Last Update: February 4, 2021)

The best keychain flashlight in 2024 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.

Most of the time we use low lumen settings even with bigger lights so even a super small light will help you in the dark. The light you have with you when you need it is the best light.

Since flashlight keychains 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 microlights 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.

Our Picks For The Best Keychain Flashlights in 2024

Best Micro Flashlight:

Olight I1R 2 EOS

Olight i1R 2 EOS

The Olight I 1R 3 EOS is the perfect keychain light thanks to its extremely compact size and its ultra-lightweight design. The size and weight of this light make it ideal for attaching to lanyards and key chains; you won’t even notice the added weight or bulk. Coming in at 1.5 inches long, this light is shorter than your average AAA battery and only weighs .42 ounces with its battery in place. The body of the light is manufactured from a strong aluminum alloy ensuring it is durable enough to be carried on most key chains.

Powered with a built-in rechargeable Lithium-ion battery, the Olight I1R 2 EOS offers users two brightness levels using a high-performance 5-sided CSP LED. The high-performance LED is paired with a TIR optic lens to produce a balanced and soft beam of light. To swap between brightness modes simply twist the head of the light.

The built-in battery is recharged by plugging the Micro-USB charging cable into a compatible power source. Full recharging of the battery takes 1 hour and 15 minutes, but the charging indicator light will alert you to the recharging process. With an IPX-8 rating the Olight I1R 2 EOS is able to be submerged in up to 2 meters of water for up to 30 minutes without suffering permanent damage. The simplicity and small size of this light make it one of the best keyring torches available.

Best Runner-Up Micro Flashlight:

Astrolux M01

Astrolux M01 itimce

If you are in the market for a small, durable key chain style light you need to consider the Astrolux M01 100LM USB Mini LED Flashlight is an excellent choice. When compared to the Olight I1R EOS, the Astrolux M01 comes up short in a few different places which is why it is our runner-up rather than the best option in terms of micro flashlights. Featuring a Nichia 219C/XP-G3 LED the Astrolux M01 is able to emit a maximum of 100 lumens, so it’s not quite as bright as the Olight, but it’s lowest setting at 8 lumens is brighter than the Olight. The twisty style switch allows users to swap between high and low brightness modes.

The stainless steel body of the Astrolux M01 is not only durable but is a partial choice for the numerous ways this light can be used. The body of the light is used as the switch to provide power and swap between modes, simply twist the body to power the light on or off. The Astrolux M01 is powered by a 10180 battery which comes included within the light. To recharge the battery, remove the lens housing and plug in the micro-USB into the light and a compatible power source. Charging takes about an hour to complete and is monitored through a charging indicator light.

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 fits the bill. Our favorite charger for the Eneloops is the Opus BT C3100 since it easy to use, high quality, and works for both AA and AAA batteries. For non-rechargeable batteries the Energizer L92 batteries are superior, they are lithium and not alkaline so they have more charge and longer shelf life.

Best AAA Flashlight:

The Prometheus Beta QRv2 is the updated version of the original Beta QR. With this updated version users will receive the same core qualities that the original version offers, including superior beam quality and an appealing design, but you also get so much more.

Super Durable AAA Keychain Flashlight:

Sofirn C01S

Sofirn C01S EDC AAA keychain Flashlight, Bright 100 Lumens Luminus SST20 Mini Kids Light

The small, key chain sized Sofirn C01S is the updated version of the Sofirn-BLF C01. One of the most important updates is the light’s ability to produce a maximum of 100 lumens.

The compact size of the light and its lightweight design ensures users never notice it on their keychain, but the tail cap design allows for tail standing and offers a round hole for a magnet and a trit hole. A great light that would be good as a survival flashlight.

The Nitecore TUP is a great little light that has been designed from the ground up to be a great keychain flashlight. Nitecore has been working for years on these smaller type lights like the TUBE and TIP which are some good goto lights for a small rechargeable light.

The Nitecore TUP utilizes a CREE XP-L V6 LED to emit a maximum of 1000 lumens. The light offers 5 different brightness levels: turbo, high, medium, and low, and ultralow. The light offers a user-friendly interface with lots of options. The small OLED display can show Battery level & voltage, brightness level, the user mode, and remaining runtime. There are two user modes for the light, demo and daily, demo makes it so the light will shut off after 30 seconds if there is no operation so you can use this for quick light and on and off and you do not need to worry about killing your battery.

We really like that both the turbo and moonlight modes can be accessed directly from the light being off. For turbo hold the mode button down and for moonlight hold the power button down. This light comes with a great super deep pocket clip but for the purpose of being a keychain light Nitecore has put a solid stainless steel ring at the bottom that is ale to withstand up to 30 kilograms of weight or 66 pounds.
