Our top picks: Best Keychain flashlight contenders

Unlike most of the “Best keychain flashlights” lists you have found on Google, we have owned and reviewed hundreds of flashlights on our team. Many of those lists you saw are written by people who know nothing about flashlights! In fact, many of these people do not even own any flashlights they recommend.

1000 lumen keychain flashlight

Nitecore TUP : 1000 lumen keychain flashlight

Holding Nitecore TUP in hand 3
runtime graph

The Nitecore TUP is a performer and may look a little unusual with the 2 switches and OLED display. But when you press that switch…. you will blind yourself with a solid 1000 lumens. We have evaluated the Nitecore TUP, and it really reached 1000 lumens! Unlike many other brands on eBay or Aliexpress, this is the real deal. 

If you are searching for something lightweight, but don’t mind the bit chunky-sized keychain light, this is a great way to get ahead of the game. The OLED display tells exactly how many more minutes the battery will last. The peak brightness can only be reached while pressing the button continuously. So the highest constant output mode is 200 lumens.

This is why we would recommend this flashlight

  1. In our test we saw it really reached 1000 lumens at turn on
  2. Very lightweight
  3. Has an OLED screen that tells you the voltage, and remaining time

One con is the older type Micro USB port.

Best Rechargeable keychain flashlight

Actually, most, if not all of the flashlights on this page are rechargeable.

OLIGHT I1R 2 PRO

Olight i1R 2 PRO runtime first 1 hour

Let’s start off by saying that the claimed 180 lumens isn’t true.. nope, we measured 226 lm at turn on. Not bad for such a small light. On the highest output setting, you get about 30 minutes of runtime. And on the lowest setting, you get over 15 hours.

The Olight i1R 2 PRO is very tiny, albeit not as small as its predecessor, the i1R 2 EOS. It includes a tiny built-in battery that is not replaceable. So keep that in mind. You need to twist it to turn on and untwist it to turn off. By quickly tightening – loosening – tightening you get to the other mode setting. It’s pretty straightforward if you understand the concept. Olight is a well-known flashlight brand that makes high-quality products. You can’t go wrong with the Olight I1r 2 PRO!

This is why we would recommend this flashlight

  1. Great output for such a small flashlight, we tested 226 lumens instead of the claimed 180 lumens
  2. USB-C charging, which makes it easy to charge anywhere you are
  3. Siple twisty UI with only 2 modes

Popular AAA flashlights for on your keys

Lumintop EDC01

Lumintop EDC01 runtime

AAA flashlights are probably one of the most popular keychain flashlights since AAA batteries are widely available. However, we do not recommend using Alkaline batteries, like Duracell. We have experienced and read about too many instances where Alkaline batteries leaked, and even damaged flashlights almost beyond repair. Instead, we only recommend using rechargeable AAA batteries like Panasonic Eneloop. These rechargeable batteries can be charged hundreds of times and they save you money in the long run.

Want all the juicy details? Head over to our Lumintop EDC01 review.

This is why we would recommend this flashlight

  1. It’s very affordable at around $10
  2. It doesn’t have a normal mechanical switch, so less chance of breaking
  3. Works on AAA rechargeables, and primaries in case of an emergency
  4. It’s available in different colors, so it’s great for gifting
  5. It has 3 modes, and the lowest mode runs for 26 hours nonstop

Popular single AA Keychain flashlight (for EDC)

Lumintop TOOL AA 2.0

The best Lumintop Tool AA 2.0 in different colors
Lumintop Tool AA 2.0 runtime High

If you’re looking for a reliable AA flashlight have a look at the Lumintop Tool AA 2.0. It’s extremely popular amongst flashoholics. It’s available in 3 different colors as well as in titanium. We reviewed the Titanium Tool 2.0 AA light here. Although they work with 14500 Li-Ion batteries, we wouldn’t recommend them using for any longer than 10 seconds at a time. With AA batteries it’s no problem to keep them on in Turbo.

The Lumintop Tool AA2.0 has 3 different modes. Simply press the tail switch quickly to change modes.  The great thing about AA flashlights is the extended battery life compared to an AAA flashlight. (about 3 times as long) But at the cost of a larger size. We do not recommend Duracell Alkaline batteries. Actually, we don’t recommend Alkaline batteries in general. You are much better off buying rechargeable batteries. Especially ones that are made in Japan. Those are constantly coming up at the top of every rechargeable battery test.

This is why we would recommend this flashlight

  1. We measured over 250 lumens at turn-on with AA battery
  2. Can be used with a 14500 battery besides AA’s to reach over 600 lumens
  3. A diffuser is included to turn your flashlight into something like a candle or mini lantern
  4. Has 4 main modes
  5. Quick access to Strobe (when on: press and hold the side switch)
  6. Optional magnetic tailcap

Mini keychain light (most advanced compact keychain light we tested)

Lumintop Frog

Lumintop Frog runtime

If you’re looking at something really small, and extremely bright… for split second… this is it.

There are no real other options other than the Lumintop Frog, which is this small and reaches such a high output. With the 10180 battery, we measured 598 lumens at turn on, and 858 lumens with the 10440 battery.

The 10180 battery has a capacity of just 80mAh.. yes, you read that correctly. 80mAh is like a blink f an eye.. just kidding. So, I would suggest getting the optional 10440 battery tube, and a 10440 battery.

If you’re a flashlight enthusiast, you can program the UI to your liking. It uses the NarsilM firmware  12 different mode sets, including a stepless ramping mode.

The package includes a charging adapter with a USB-C charging port and charging cable, so you don’t need to buy a special charger separately.

Interested in learning more about this little keychain monster? Read our Lumintop Frog review.

This is why we would recommend the Lumintop Frog

  1. Available with 10180 and 10440 battery tube, so you can choose how long you want it to be, and 10400 has much more capacity for longer runtimes
  2. Maximum lumen output: 750 lumens (we tested 858 lumens at turn on with 10440 battery)
  3. Great for flashlight enthusiasts with multiple mode groups to choose from
  4. It has onboard charging

Nitecore Tube v1

If you’re looking for a very thin and lightweight rechargeable keychain light, this may be your best bet. Nitecore is a premium flashlight brand that produces great craftmanship. Although usually in the higher segment, they also have some affordable flashlights like the T series Tube. This Nitecore keychain light is available in multiple colors, including pink (for the other half), and is a great gift for your non-flashaholic friends and family. Simply add the light to their keychain and they’ll be happy. Don’t expect anything bright, since it uses a simple 5mm led, and not a high-power LED! The maximum output is about 45 lumens. Want to know more, check out our Nitecore tube review.

This is why we would still recommend the old Nitecore Tube v1

  1. If you want a very simple keychain light with almost no weight
  2. Available in different colors, so you can mix and match with your other EDC gear, or clothes
  3. Built-in rechargeable Li-ion battery with a runtime of up to 48 hours in the lowest output mode.
  4. Simple UI with only 2 modes

Sad to see it still uses the old Micro USB port. Ther is also a newer v2, but it has a different UI

Q&A about buying a keychain flashlight

Some of the most common questions asked when it comes to Keychain flashlights:

  • Which brand makes the best keychain lights?

    That’s a really tough question to answer. There are many great keychain lights made by different manufacturers. But there are just a few that focus mainly on keychain flashlights, and 1 of them is RovyVon. Please have a look at the reviews we’ve done of the RovyVon S3, and RovyVon Aurora A9.

  • What is the most powerful keychain flashlight?

    That is probably the Nitecore T4K we reviewed, which reaches to about 4000 lumens.

  • What’s the smallest keyring flashlight?

    It depends on what you mean by small. You can get them as cheap and small as you want. But the smallest, but most powerful keyring flashlight we reviewed is probably the Lumintop Frog, with over 700 lumens

Smartphone vs a versatile keychain EDC flashlight

14 reasons why you should use a keychain flashlight over your smartphone light

There are a few things that you can keep in mind when choosing between a keychain light and a smartphone light.

  1. Many keychain lights have replaceable batteries. So in case of an emergency, you’re likely to be able to find a spare battery, and your phone doesn’t. You likely want to save battery on your phone in these situations.
  2. Smartphone lights don’t light up things farther than a few feet away from you. So a dedicated keychain flashlight is likely going to let you see farther away than just a few feet in front of you.
  3. A keychain light can take some abuse, and it’s easier to lend out to somebody. Especially if you only have an expensive smartphone.
  4. In case of an emergency, you might need both at the same time, so having an extra keychain light with you can be crucial.
  5. In most cases, your cellphone light is very limited in terms of functionality. It’s usually an on/off, and no options like high mode, low mode, to extend battery life or have an SOS feature to let other people know where you are.
  6. Keychain lights are likely easier to use when you need both hands than your mobile phone.
  7. If it’s a real emergency, you want to save your phone’s battery
  8. Most keychain lights are much more powerful and can light up a larger area / space
  9. A keychain light is smaller, and therefore much easier to take with you than a phone.
  10. Keychain lights can be used by smaller children, and you don’t need to worry about them breaking your screen
  11. You can lend out your keychain light while keeping on to your phone in an emergency situation
  12. Keychain lights are more water-resistant
  13. Keychain lights are more impact resistant
  14. 2 is one, and 1 is none
