10 Best Keychain Lights 2025 in the United States

The OLIGHT IMINI 2 EDC rechargeable keychain flashlight is an excellent choice for those who need a compact and portable light source for everyday carry or emergencies. With a brightness of 50 lumens, it provides a wide and balanced light output that should be sufficient for most general uses. The flashlight's small size (2.17 inches long) and light weight (0.69 ounces) mean it won't be cumbersome to carry around on a keychain or in a pocket. Its aluminum body, rated with a 1.5 meters drop resistance, adds to its durability, making it a reliable option for daily use.

The magnetic base is a convenient feature that allows for hands-free operation by attaching the flashlight to any iron surface, which can be very handy in many situations. The integrated USB plug for charging is another thoughtful design element, offering the convenience of recharging within 60 minutes using any standard USB adapter. Additionally, the flashlight is waterproof with an IPX6 rating, so it can withstand splashes and some exposure to water.

On the downside, the 50 lumens output might not be sufficient for users who require a very bright light source for specific tasks or for illuminating larger areas. The beam distance of 1.5 meters indicates it is more suitable for close-range tasks rather than long-distance lighting. Moreover, it has a single light mode, which might be limiting for those who prefer multiple output settings. In summary, the OLIGHT IMINI 2 is a practical and user-friendly keychain flashlight that excels in portability and durability, making it ideal for everyday carry and general use, though it may not meet the needs of users who require higher brightness or more versatile lighting options.

The RovyVon A3 Gen 4 Keychain Flashlight boasts impressive brightness with 650 lumens, which is quite powerful for a flashlight of its size. It's USB-C rechargeable, making it convenient as you can use any USB-C cable for charging, although the cable isn't included. This flashlight is compact and lightweight, ideal for carrying around in your pocket or attaching to your keychain, which suits well for everyday carry, camping, hiking, and emergency situations.

The innovative design prevents accidental activation, which is a useful feature for those who carry it in bags or pockets. Its durability is marked by a sturdy aluminum case and an IPX6 water resistance rating, meaning it can handle splashes and rain but shouldn't be submerged in water. The magnetic base and clip add versatility, allowing hands-free usage on metal surfaces, which is great for tasks like fixing a car or working on projects.

However, the beam distance is moderate at 80 meters, which might be less than expected for certain outdoor uses, and the initial setup with five clicks to unlock might be cumbersome for some users. Additionally, a downside is that it requires one LR41 battery, which might not be as common or convenient as other battery types. Despite these points, the RovyVon A3 Gen 4 is a powerful and portable flashlight suitable for a variety of situations and tasks.

The Streamlight 73300 Pocket Mate keychain light is a compact and lightweight option perfect for those who need a reliable light on-the-go. With a brightness of 325 lumens on high and 45 lumens on low, it offers sufficient light for various tasks. The beam distance of 76 meters on high and 28 meters on low ensures adequate visibility. The polycarbonate material makes it durable, and it is water-resistant with an IPX4 rating, so it can handle splashes and light rain.

One of its standout features is its USB rechargeable lithium polymer battery, which charges in about 4 hours and eliminates the need for disposable batteries. The battery life, however, is quite short on high mode, lasting only 20 minutes, but it extends to an hour on low mode. The keychain light also comes with a spring-loaded clip that can easily attach to key rings, zippers, or lanyards, adding to its portability.

Despite its small size of 2x1.08x0.5 inches and weight of 0.8 ounces, it packs a punch in terms of performance. The multi-function push-button switch with a charge indicator is a convenient feature, although some users might find the low runtime on high mode a drawback. Ideal for activities like cycling, hiking, or personal safety, it provides a good balance between size and functionality. The silver finish adds a sleek look, and the included components like the user guide, battery, charging cable, and flashlight make it a complete package.
