10 Best Keychain Flashlights 2025 in the United States

The OLIGHT IMINI 2 EDC Rechargeable Keychain Flashlight is a compact and portable mini LED light that delivers 50 lumens of brightness. Its small size (55 mm long) and light weight (19.5g) make it easy to carry on a keyring without adding bulk. The flashlight is constructed from durable aluminum, offering drop resistance up to 1.5 meters, which is great for everyday carry and emergencies.

The built-in rechargeable battery is a convenient feature, as it can be charged directly via the integrated USB plug, achieving a full charge in just 60 minutes. This makes it very user-friendly and cost-effective over time. The magnetic base is a handy feature, allowing for hands-free use by attaching to any iron surface, which can be very useful in various situations.

However, the flashlight does have a few limitations. With just 50 lumens, it may not be bright enough for all users or situations, especially those requiring a more powerful light source. Additionally, it seems to have a single mode output, which limits its versatility. Despite these points, the OLIGHT IMINI 2 is an excellent choice for those looking for a reliable and incredibly portable flashlight for everyday use or emergency situations.

The Streamlight 66609 MicroStream is an ultra-compact flashlight that delivers impressive brightness levels, making it a practical choice for everyday carry (EDC). With a high setting of 250 lumens, it provides a strong beam that reaches up to 68 meters and runs for 1.5 hours. The low setting offers 50 lumens and runs for a longer duration of 3.5 hours, which is useful for conserving battery life when less light is needed.

The flashlight is powered by a rechargeable battery and includes a convenient USB charging feature, though it is important to note that the standalone battery is not sold with the product. The flashlight's aluminum construction ensures durability, making it capable of withstanding daily wear and tear. Additionally, its lightweight and portable design, along with the included removable pocket clip and high-strength lanyard, enhance its practicality for on-the-go use.

The multi-function push-button tail switch with a charge indicator adds to the ease of use by clearly showing the charging status. However, some users might find the need to slide the metal sleeve to access the charge port slightly cumbersome. Additionally, while its impressive brightness is a strong point, the flashlight's limited runtime on the high setting may be a drawback for those who require longer continuous use. In summary, this flashlight is well-suited for those seeking a durable, bright, and highly portable lighting solution for everyday tasks, provided they don't mind the relatively short runtime on the highest setting.
