The Best Keychain Flashlights for Convenient Carrying

Keychains have been around for a very long time and are as prominent in the souvenir industry as they have ever been. Of course, aside from being little trinkets that serve as a reminder of your latest trip to you favorite theme park, they can also be very handy to have around, especially when they happen to be flashlights. The problem with keychain flashlights it that they are often very cheap and not very bright and just all around poorly made. However, there exist a lot of them that are actually well-made and don’t feel like trash. I’ve compiled a list of some of the best keychain flashlights that you can count on to not break within an hour.


Olight LED Keychain Flashlight

This flashlight has a pretty ingenious design. To circumvent the hassle of changing batteries, this light has incorporated a mini USB port into the side of the battery unit to allow it to be recharged. The half of the flashlight with the battery is connected to the half with the bulb by screwing the two parts together. The half with the bulb covers the USB port and can change the brightness of the light depending on how much its screwed in. All these features are compacted into a flashlight the size of a thumb, which is optimal for something that’s going to be carried around.

Brightness: 130 lumens

Length: 1.6 inches

Battery Life: 1 hour


Aidier A7 LED Keychain Flashlight

Not only does this flashlight have a keychain, but it’s got a clip as well. It’s super small and can produce a beam up to 180 lumens in brightness. And if that’s too bright for you, it has a low beam of 50 lumens. With anti-slip technology and a power button at the end of the body, this flashlight is perfect for single-handed use. It also apparently works as a headlight, which would make sense given you had something to clip the flashlight to.

Brightness: 180 lumens

Length: 3 inches

Battery Life: 2 hours


Aurora Rechargeable Keychain Flashlight

This one is tiny and is almost three times brighter than the previous flashlights, but it has a bit of a higher price tag. It’s rechargeable (via mini USB) and has a removable clip if you want to, well, clip it onto something. It’s not perfectly cylindrical down the entire body and has a flattened area near the keychain hole, which gives it a nice aesthetic, if you’re into that sort of thing. If you’ve got a higher budget and want something small and bright, then look no further.

Brightness: 550 lumens

Length: 2.1 inches

Battery Life: 1 hour


KeySmart Nano Keychain Flashlight

This one is very simplistic and is activated by twisting the body to circumvent the need for buttons. It comes with four small cell batteries (not rechargeable) and lasts for quite a long time. However, it’s not very bright and clocks in at only 25 lumens (that’s about the equivalent of two candles). But if you’re looking for something that’s super small, then you won’t find a decent light that’s much more compact than this.

Brightness: 25 lumens

Length: 1.8 inches

Battery Life: 10 hours


Letmy LED Keychain Pen Flashlight

This is a flashlight that’s small and sleek and actually fairly bright. It’s sleek aluminum body not only looks cool with its simplistic design, but makes it a better candidate for getting carried around. And, on top of it all, this flashlight has a very small price tag. If your budget for a keychain flashlight isn’t that high, then this one is a good option.

Brightness: 120 lumens

Length: 3.7 inches

Battery Life: 1 hour


Helius LED Keychain Flashlight

Here’s a flashlight that looks like something you’d find on an alien spaceship. Although not really from another planet, this little thing not only works as a flashlight, but also as a glowstick. The green bands you see are apparently made from glow-in-the-dark material to help you find your flashlight in the dark. It’s also rechargeable, which is good if you don’t like replacing batteries. Although a bit on the spendy side, this flashlight definitely makes a statement.

Brightness: 130 lumens

Length: 2.8 inches

Battery Life: 1 hour


Nitecore TINI Keychain Flashlight

This one is blockier than most flashlights and looks a bit like a camcorder. But instead of capturing footage, this thing just spits out light. It’s fairly bright and is even rechargeable, but the price is pretty steep. However, if you’re looking for something unique and super portable, this thing is just that.

Brightness: 380 lumens

Length: 1.7 inches

Battery Life: 2 hours


Idakey Multipurpose Keychain Flashlight

You might be thinking, “this isn’t a flashlight!” Well, it may not be a flashlight in and of itself, but if you’re going to carry something around with you, why carry a flashlight when it can be a bottle opener too? Unfortunately, that’s the only other tool this thing has, unless you count the nifty clip on the end, which could be used to hang the light from somewhere. It also has two sizes of key rings if you’re picky about that kind of thing. All in all, this is a great choice for someone who wants a flashlight and happens to use a bottle opener a lot.

Brightness: 25 lumens

Length: 3.3 inches

Battery Life: 3 hours


These have been some of the best keychain flashlights on the market. It can be hard to make a flashlight super high quality when it needs to fit on your keyring, but I feel these ones have done just that. Now you’ll always be able to see where you’re goingthat is, assuming you don’t lose your keys.
