Why You Should Consider Having a Keychain Flashlight

Here are 5 reasons why you should consider having a keychain flashlight:

  1. It helps you stay prepared for any emergency: Having a flashlight in your keychain means that you have a good source of light with you at all times. Emergency situations can pop up unexpectedly at any time and you never know when you might need a flashlight. A keychain flashlight may be the tool that helps you get out of a tough situation when you cannot lose precious time looking for another source of light. It is a great little tool that helps you stay prepared for anything that might come up.
  2. It helps you feel secure: Do you often feel a little intimidated walking across the dark parking lot to get to your car? A keychain flashlight is just what you need. It is the tool that can help you feel more secure in certain situations. Carrying a large flashlight at all times is not the most practical thing, and keychain flashlights are bright enough to keep predators away and make you feel safe and secure when you need it.
  3. It is portable and compact: A keychain flashlight is compact and portable, making it convenient to carry around every day. And as mentioned, they are small but incredibly bright. This makes them great for places where you cannot use portable camping generators or carry a large tactical flashlight. A keychain flashlight’s size and portability make it a great accessory for EDC, camping and traveling.
  4. It is powered by replaceable batteries: You can use a keychain flashlight for as long as you want. They are powered by normal, replaceable batteries so when your light source runs out of power, all you have to do is replace the old batteries with new ones. The batteries are easy to replace so even in tough situations when you run out of light, you can put in new batteries and immediately have bright light to help you.
  5. It is durable: When you think of a keychain flashlight, you might picture a small, flimsy light source that will break if you drop it, etc. Not so. Keychain flashlights these days are made of sturdy and durable materials, such as aluminum. This means that they are tough and can last a really long time. A keychain flashlight is a great backup when your flashlight stops working when you need illumination the most.
  6. It is an essential add-on for outdoor equipment: Although it is tiny, a keychain flashlight is an essential add-on accessory when you are putting together your equipment for outdoor activities like hunting, camping, hiking, etc. Since it is integrated with your keys, it is highly unlikely that you will miss them. While you are out in the wilderness and need a light source immediately, but do not have time to look for your flashlight, your keychain flashlight will be easily accessible to give you the light you need no matter where you are.

As you can see, there are many benefits to having a keychain flashlight so you should definitely consider getting one.

Although it might be a tad heavy for some compared to many other keychain flashlights out there, we think that it is the perfect size and weight for EDC and outdoor trips.

It is tough and it is easy to find because of the weight. If you want something lighter though, there are other options that perhaps will satisfy you a little more pertaining to this aspect.

The twist-on switch tends to activate the flashlight when it is in the pocket, draining the battery. This can be a bit of an issue because the batteries are not cheap at all. We find it safer to attach it to a belt loop to avoid this. But all in all, the TerraLux Micro is overall an excellent keychain flashlight that is not overpriced and so we do recommend it.

Concluding Thoughts

It is a sagacious idea to always have a flashlight with you – you never know when you might need one. A keychain flashlight is a marvelous tool to have as it helps in making sure that you have solid illumination when you need it.
