Why Do You Need a Keychain Flashlight?

A handheld flashlight is a useful tool, but you may not be able to carry it everywhere because it takes up space. However, it is impossible for you to not to take your keys everywhere you go, and most of the time, you wear clothes with pocket.

A keychain flashlight is a recommended illuminating device that you can take everywhere with you because you can keep it in your pocket or attach it to your keys. With a keychain flashlight, you might not even remember that you have a handy device with you all the time.

Emergencies and accidents are inevitable. No one has the ability to predict when these kinds of situation will come. It is important to be prepared. A keychain flashlight is an all-around tool that you can use for situations like these because of the following reasons:

Small Enough to Fit Into Small Spaces

If there’s something that crawls into your friend’s ear, you’ll be able to see it right away. A keychain flashlight is small enough to provide a directed light towards small spaces like ears, nose, mouth, small holes, and the like.very small flashlight keychain

Has the Ability to Light Up a Dark Environment

This type might not be as powerful and durable as a handheld flashlight. However, even the smallest keychain light has the ability to light up a dark room. You may use it as a back-up if your handheld flashlight runs out of power during the time of emergency.

Can be Used to Signal

You can use your keychain flashlight to let the other people know that you are in there. This is especially important when you are in a dark place and there are passing vehicles that may accidentally hit you when they can’t see you.

How to Buy the Best and Long-Lasting Keychain Flashlight

1) Choose LED – Keychain flashlights with LED bulb are brighter and long-lasting. Because of this, LED keychain flashlights are cheaper compared to incandescent Maglite. If you’re using an incandescent Maglite, you will have to change your flashlight more often.LED keychain flashlight

2) Consider the Battery Type Requirement – The most recommended battery type is AAA lithium battery. Lithium battery tends to last longer. Some say that it can last up to ten years if the keychain flash light is not often used. Don’t use a NiMH battery because it drains faster. In the end, you’ll be spending more money using a NiMH battery.

There’s nothing wrong with button cell battery for a small flashlight, however, it’s not always available in nearby stores, unlike the AAA battery.

3) Check the Keychain Attachment – It is important to consider the keychain flashlight’s metal ring or carabiner. Make sure that your flashlight will snug tightly into the thing where it will be attached. Make sure that it won’t easily detach from slight friction or impact. You don’t want to lose either of your keys, wallet, or your flashlight because of a weak keychain attachment.

4) Test Before You Buy It – If you want to buy a keychain flashlight directly from a store, make sure to test it first. Testing ensures the quality of the product and that you’re not wasting your money on a defective device.

This may not be applicable when you’re purchasing the keychain flashlight online. However, you can check the warranty of the product or the return policies of the online store. Most of the time, online stores are willing to give refunds or change the defective product at no price.

5) Durability – Make sure that the keychain flashlight that you’re buying is impact-resistant. Remember that you’ll always be carrying your flashlight everywhere. There will be instances that you may accidentally drop it, sit on it, or throw it along with your keys.sturdy keychain flashlight

6) Know What You Want – Every keychain flashlight has its own unique features that make it saleable in the market. Sometimes the strong points of the product lead to some pitfalls. That’s why it is important that you should know what you want and what you’re willing to sacrifice.

For example, there are products that can be labeled as the brightest keychain flashlight in the market. However, the common disadvantage of this is the shorter running time of twenty to thirty minutes.

There are other keychain lights that offer other tools, like a can opener, along with the flashlight. However, these kinds of keychain light may be a little bit bulky or destructive to your pocket or to your bag.

How to Take Care of Your Keychain Flashlight

Find time to clean your keychain flashlight. Remember that your illuminating device is made from metal. Dirt and mud can cause it to rust unless your flashlight is rust-resistant.

  • Keep it Away From Destructive Chemicals – Destructive chemicals like acid may also be destructive to your flashlight. That’s why it is important and safe to place your keys (along with your flashlight) away from damaging chemicals.
  • Protect It From Water – Although there are types of keychain flashlights that are water-resistant, it is still important to keep your device away from too much exposure to water. Some products that claimed to be water-resistant can only tolerate an exposure to small amount of water like droplets and splash. It doesn’t mean that your device can emerge in water.
  • Lube it – It is important to lube your flashlight for once in a while especially if you’re not using it often. The O-Ring might get stuck if you’re not using your flashlight often.


In the above-mentioned products, the best keychain flashlight is the Olight i3E because it has the most positive features of the different keychain flashlights. It is inexpensive, bright, durable and weatherproof.
