Frequently Asked Questions

Q: How long does the COB keychain flashlight battery last on a single charge?

A: The built-in 500mAh polymer lithium battery provides extended runtime that varies by mode. On low/weak light modes you can expect several hours of use; on the super-bright long-press mode, runtime is shorter. The LED power display lets you monitor battery level so you're never caught off guard.

Q: How do I charge the ESMARTER keychain flashlight?

A: Charging is simple — just plug the included Type-C cable into the flashlight's charging port and connect to any USB power source. Type-C fast charging means you'll be back to full brightness quickly.

Q: Is this flashlight waterproof?

A: This model is not rated waterproof, so it's best kept away from heavy rain or submersion. It's ideal for everyday carry, camping, hiking, and vehicle use under normal dry conditions.

Q: What extra tools are built into this keychain flashlight?

A: In addition to the 7-mode COB LED light, the unit includes a window hammer for emergency glass breaking, a screwdriver tip, and a seat belt cutter — making it a compact multitool designed for everyday preparedness.

Q: Can the magnetic base hold the flashlight on its own?

A: Yes! The strong magnetic base allows you to attach the flashlight hands-free to any magnetic metal surface — great for under-the-hood car work, tent poles with metal clips, workshop benches, or any scenario where you need both hands free.
