AirTags are great. Until they’re not.
And for me, that moment always seems to arrive right when I actually need to find something. Like clockwork, I go to check the location of whatever item the AirTag is supposed to be tracking... only to find out the battery died sometime last month. Or maybe longer. Who knows.
So when I came across the TimeCapsule by Elevation Lab, I was in. It’s a purpose-built case for your AirTag that takes the standard “replace this tiny disc battery once a year" model and completely flips it. Instead, it runs off two AA batteries and gives you up to 14 years of battery life. That’s not a typo. Fourteen.
The design is clever. You remove the shiny metal back from your AirTag, drop the white part into the enclosure, and the TimeCapsule’s internals connect directly to the AirTag’s battery contacts. It comes with a little hex wrench to screw the whole thing together. No soldering, no weird hacks - just a clean swap. They recommend Energizer Ultimate Lithium AAs for the longest lifespan. Alkaline batteries do technically work, but they don’t last nearly as long and may leak over time. So don’t cheap out.
The build is no joke either. The TimeCapsule is IP69 waterproof, shockproof, and (according to the manufacturer’s information) is made from an 'ultra-durable fiber-reinforced composite. It’s not flashy. It doesn’t scream "tech device." Honestly, it kind of just looks like a sturdy little tool case, which is ideal if you’re putting it on something you don’t want attracting attention. It measures about 4.45 inches long, 1.57 wide, and 0.75 tall. Big enough to house the batteries, but still discreet enough for backpacks, camera gear, trailers, or toolboxes.
The only tradeoff I can find, aside from being larger that a standard AirTag, is sound. Since it’s sealed, the tag’s chirp is slightly muted to about two-thirds the volume of a ‘naked’ AirTag. Still plenty loud enough for most use cases, but still something to note if you’re planning on playing audio Marco Polo in a noisy environment.
For anything critical though, like luggage, motorcycles, gear bags, or snowmobiles, this little case feels like a no-brainer. It takes the AirTag’s weakest link (the battery) and turns it into a long-term asset. No charging. No annual reminder. No dead tag when you need it most.
Honestly, if Apple made an "AirTag Pro," this is very possibly what it would look like.
