Keychain Flashlight Reviews – The Small Ones Are the Best Ones

A flashlight isn’t much help if you can’t easily access it when you’re in the dark. And what better way to keep something with you than by putting it on a keyring? That way, you can hook it onto almost anything including your belt, backpack, or purse and you won’t have to worry about it falling on the floor when the power goes out.

In this article, I’ll be presenting some keychain flashlight reviews that will hopefully shed some light on whether they are any good. After reading this article, you should be able to make an educated decision on the keychain flashlight that’s right for you.


Aidier A7 LED Keychain Flashlight

This is a flashlight that’s very small and super bright, as a keychain flashlight should be. It’s waterproof and impact-resistant and has three different light modes. It has a sleek aluminum body with lots of knurling to prevent it from slipping out of your hand. The power button is found at the tail end of the body, which makes it even more compact. It comes with a removable clip in addition to the keychain ring, which makes it very versatile. 

Brightness: 180 lumens

Length: 3 inches

Battery Life: 2 hours

People have found this flashlight to be very comfortable to hold and very easy to use. Not only can you change the light mode by giving the tail button a half-press (that means no clicking sound), but you can simply twist the head, which is screwed on. The threads of the screws that connect the head to the body (as well as the ones that connect the tail to the body) are greased, making it easy to twist. 

The box you get the flashlight in not only comes with extra key rings but also a glow-in-the-dark diffuser you can put on the head of the flashlight, which basically turns the light into a lantern. One problem owners of this flashlight have reported is that the keyrings are very hard to get on, which makes sense given the size of the flashlight.


  • Small, compact, and bright
  • Very quality finish
  • Greased screw threads
  • Glow-in-the-dark components


  • Awkwardly sized keyring

Overall, this is a pretty solid flashlight. As far as keychain flashlights go, this one is fairly mid-tier in terms of brightness and price. It’s the cheapest one on this list, so I would recommend it for anyone with a lower budget. It also has a satisfaction guarantee policy that allows you to return it if you aren’t happy with it.

Olight LED Keychain Flashlight

This flashlight is super small and compact and is turned off and on exclusively by twisting the body. It has a built-in lithium ion battery that’s rechargeable through a micro USB port. It’s water-resistant and weighs less than half an ounce. It doesn’t have any special features other than two brightness settings, but its minuscule size more than makes up for that.

Brightness: 130 lumens

Length: 1.6 inches

Battery Life: 1 hour

A lot of people have been surprised at just how bright this little thing is. It can easily be concealed in a fist, but can pump out enough lumens to light a path for several people. Of course, being the size it is, it doesn’t take very long for the battery to deplete, which is one of the problems with this light. 

Others have complained about the fact that the light is activated by twisting the head. Not only does this require two hands, but it has led to accidental power-ons—and some people have even lost one of the halves entirely.


  • Incredibly small and lightweight
  • Bright and dim light settings
  • Rechargeable


  • Short battery life
  • Inconvenient mode of activation

This flashlight is about as small as you can get for how bright this thing is. The battery life shouldn’t be that big of a problem if the flashlight is only used for brief periods of time (such as walking to the car). If you can get past the fact that it requires two hands to turn off and on, then this is a solid choice. This one is a little more expensive than the last flashlight, but is definitely reasonable given how compact it is. So, if size is your biggest concern, then look no further than the Olight I1R.

Aurora Rechargeable Keychain Flashlight

More than three times brighter than either of the previous flashlights, this thing is a little powerhouse—and it’s only two inches long. It has three different light modes (low, high, medium, and strobe) that can be changed with the press of the power button. It’s also waterproof, impact-resistant, and rechargeable. 

Brightness: 550 lumens

Length: 2.1 inches

Battery Life: 1 hour

One thing people appreciate about this flashlight is the fact that the power button has to be held down for a second to turn it on and off. This helps to prevent accidental power-ons. And because its a button, it’s easy to use with one hand. The biggest problem with this light is how hot it can get. 

When it’s set to its maximum brightness, it apparently only runs for two minutes before dropping down to a lower brightness. While this could be annoying, you probably won’t need anything more than minimum brightness in most cases. 


  • Small and compact
  • Capable of producing 550 lumens
  • “Accident-resistant” power button


  • Can get very hot

I would recommend this flashlight if you like really bright things, even though the brightest setting only lasts for minutes at a time. It’s also great for impressing your friends and family with. If your budget is pretty high (considering this is just a keychain), then this flashlight is a great pick and will certainly be light enough for almost any scenario.
