Imagine yourself walking along a very dark alley as you go home with no streetlights. Scary, right? And then, as you reach home and grab your keys to open your door, you can’t see the keyhole because it’s too dark. What now? You still have to reach for your phone and turn on the flashlight from there. It’s a hassle, isn’t it?

Scenarios like this are the reason why having a keychain flashlight is essential! So today, we’ll tell you all about the best keychain flashlights and why it’s convenient to have them! Let’s get started!

Why Keychain Flashlights are a Trend Now

Admit it, at one point in our lives, we all needed an extra light because it was too dark around us or we were looking for something that fell under furniture where we reached blindly in the dark. Aside from our phones, there isn’t anything else that can help us during these situations. Of course, a conventional heavy-duty flashlight would be too big, and, unless you have one on hand, it isn't practical to obtain one.

Because of this, keychain flashlights are starting to become popular. Also known as EDC (everyday carry) flashlights, they are handy and perfect to fit in any type of bag you carry and can help you save your phone’s battery when you need extra light. These EDC flashlights have features that are not the same as the usual heavy-duty flashlights we know of.

Aside from the fact that they are easy to carry, keychain flashlights are very useful, especially during emergencies. They can also help us feel more secure, especially when we are alone at night. And, the most important purpose of all is that keychain flashlights can help us find things faster, especially when you’re looking for something too small for your eyes to spot quickly.

There are many different kinds of keychain flashlights, and if you are looking for one, we recommend checking out Fenix Store for different designs and in-depth features of the trendy EDC flashlights.

Kinds of Keychain Flashlights

Generally speaking, you have two types of keychain flashlights to choose from:

Rechargeable Keychain Flashlights

Rechargeable keychain flashlights will save you the hassle of having to buy new batteries when they run out of energy. Usually, these flashlights have a USB-Type C or a micro-USB port that allows you to connect them to either an adapter or even to your laptop and other gadgets to charge.

Battery Operated Keychain Flashlights

On the other hand, battery-operated keychain flashlights mean that the batteries have to be replaced once in a while. An example of a battery-operated keychain flashlight is the Fenix E01 V2.0 AAA Flashlight that is compact and easy to carry anywhere you go.

Factors to Look For When Buying the Best Keychain Flashlight

Aside from the design and charging style of keychain flashlights, other factors can help you decide which keychain flashlight is the best for you. When you have considered these factors, you’ll pick the keychain flashlight suitable for your everyday needs.


Lumen (lm) is the unit of measurement used to describe the brightness produced by a light source. Naturally, the higher the lumen rating of a keychain flashlight, the brighter the light. Before choosing a keychain flashlight with the right lumen rating, it helps to compare this with the lumen rating of common products that produce light, like light bulbs at home or car headlights.


With keychain flashlights, they usually use a combination of LED and reflector. The reflector is responsible for scattering the light produced by the keychain flashlight. There are two types:

  • Smooth reflectors: that focus the light on a narrow beam allowing the light to be projected to a farther limited area
  • Orange peel reflectors: focus the light on a broader beam which allows the light to be projected at a larger area


Beam Throw

Beam throw, usually measured in feet or meters, is the maximum distance that the light can extend from the head of the keychain flashlight. To achieve a high beam throw, you need a keychain flashlight that has a high lumen rating and uses a smooth reflector. However, remember that the illuminated area becomes narrower as the light gets farther from the flashlight’s head.


Keychain flashlights are made with various materials, and it is up to you to choose what material you like best. A durable keychain flashlight is also one that is water-resistant so that it can still be useful during emergencies like heavy floods and heavy rains.
