Headlamp Headlight Rechargeable Waterproof Headlamps
Amazon's catalog no longer lists this product (checked 2026-11-02). The name comes from the link HN users posted.
18650 are widely used in flashlights too. I bought one from Amazon that came with a battery that has a built-in USB powered charging circuit:

Still for sale on Amazon. So it’s just bare 18650’s they won’t sell anymore?
