What is the Best Dynamo-Powered Keychain Flashlight for a PSK?

I bought a dynamo-powered keychain flashlight at a museum gift shop for a few dollars, in 2013, for my PSK. I'm currently updating my PSK. I still like the idea of a dynamo-generator powered flashlight for reliability, but I imagine there must be better ones than this, since this one is already "ancient" in terms of LED technology, and since this one was dirt-cheap to begin with. What is the best one available, as far as you know? I'm interested in features like brightness, efficiency, waterproofness, shockproofness, etc. I'm asking specifically about keychain type ones that are small, like a box of matches (small enough to easily fit in a PSK), not asking here about full-sized flashlights.

Thank you for any suggestions you can share.

Any dynamo flashlight I've had has been pretty unreliable. Apparently super-capacitor is the way to go. I've never heard of a dynamo powered light that is keychain sized.

Thank you.

The kind I bought at the museum, years ago, appears to be a Brando, as reviewed here:

Mine has not been unreliable. 7 years later, and it still works well. It has a fairly solid (metal?) body. It lights up just fine. It's just not very bright, and definitely not waterproof.

Sooner or later, I'll get this one below, which appears to be a bit larger, a bit heavier, much brighter, and more weather resistant. Since it has a solar panel on it, I would guess it's probably less durable, but it should be fine.

Not what you're asking but I would go with a Fenix e01 & a spare aaa battery.
