Best Keychain Flashlight

It's not something we often give much thought to when purchasing but when it comes to keeping us out of the dark in a pinch, a high quality keychain flashlight is one handy tool we all should have on our key rings. There are hundreds on the market which is why picking the best one for your needs is essential to ensure you'll never be left without light. Regardless of your requirements, all of us normally look to three basic things when making our selection; size and weight, power and affordability.

Based on the reviews, customers seem to favour the MecArmy PT16 and the Thrunite Ti3 for the brightest keychain flashlight and the best AAA keychain flashlight respectively. The MecArmy, although one of the heaviest on the market, stifles the competition. Few competitions are able to compete with the intense power the MecArmy PT16 is able to emit from such a small light. Customers loved the intense beam and option of 6 different modes depending on their desired use. Buyers commented on having slight hesitation to purchase this light when they saw the cost however were extremely satisfied with the product once they had the chance to test it out.

For a great all around light, the Thrunite received raving reviews for its durability, impressive power for its size, wide and even beam, and ease of use. Customers commented on the product as being a great bang for their buck as well as offering a versatility not seen with other competitions. One feature of its versatility that stood out, was the option to turn the pocket clip so it could be attached to the brim of a hat and used as a headlamp.

Overall, the best keychain flashlight is one that is lightweight, practical, and cost effective; there are many on the market but only few that light up when we think of the best.
