Keychain flashlight is basically a small flashlight and is a better option if you want to have a flashlight readily available at all times. For their size, they offer bright light with different varying brightness depending on the model, offer a good beam distance and make a great cheap flashlight for that “everyday carry” light source – whenever and wherever you need it. Keychain flashlights are also known as pocket flashlights have several benefits that you just can’t get from a larger flashlight, such as:

  • They can be utilized for light, fashion, or just another added accessory that provides value
  • An every day carry flashlight due to the smaller size and the convenient keychain ring. You can easily manage them and have them available and close to you at all times
  • Keychain flashlights utilize LED technology which provides a longer shelf life than that of a larger flashlight. There is no need to worry about changing the batteries or buying a rechargeable battery because the LED is powered by light emitting diodes so that it provides a bright light and is ready when you need it
  • Keychain flashlights are extremely affordable. You spend minimal money for a product that could potentially last you years due to its long shelf life. It is worth the small investment when you think of the years of use you will be able to get out of it
  • There are lots of options to choose from including different shapes, colors, and sizes.

When looking for the perfect keychain flashlight, keep in mind the quality of the materials used, the lumens and beam brightness, and the power source. You don’t want to buy a flashlight that has a limited run time or a limited lifespan, and you especially don’t want one if finding the replacement batteries is too difficult.

If you are looking for a cheap flashlight that still offers a great light source and decent beam distance that you can keep with you at all times on your key ring, look no further than a keychain flashlight. All of the reviewed flashlights are ideal for even the smallest jobs such as finding something in a bag in the dark or trying to find that item that rolled under the passenger seat in the car.
