A good keychain flashlight is one of those things you don't think about until you really need it. We tested five of the most popular options on actual hikes, boat nights, and everyday carry to find the ones worth your money.
I'll be honest — I never thought much about keychain flashlights until I was fumbling around on the boat at 11pm trying to find a cleat in the dark. Since then I've become a little obsessed. I've gone through probably a dozen of these things over the past few years, and I've finally landed on a handful that I'd actually recommend to a friend.
We tested five of the most popular options across three different use cases: hiking and camping, everyday carry, and marine/sailing use. Here's what we found.
What to Look For
- —Lumens — 100+ lumens is plenty for most uses. More isn't always better on a keychain.
- —Battery type — rechargeable (USB-C) vs. replaceable (AAA/CR2032). Rechargeable wins for convenience.
- —Water resistance — at minimum IPX4 (splash proof). IPX8 if you're on the water.
- —Size and weight — it's going on your keychain. If it's annoying to carry, you won't.
- —Runtime — how long does it actually last at full brightness?
