Spot on
I was dubious about purchasing this as I didn't think it would work at all and surprisingly it does, it sits perfectly in my Perun 2 OLIGHT head torch as I only had 1 21700 battery which is on it's way out and had a stash of 18650's from a previous head torch, this converts my 18650s with ease and saves me having to buy yet more batteries for my head torch and the batteries i have are high capacity and will ensure longevity

Check before buying.
Doesn't always work with every torch,so check before buying.Used this adapter with a Sofirn brand torch and Flat top 18650 batteries and worked fine.Not so with Olight,so check before purchase.

Does not work
Bought these to convert 18650 into 21700 for multiple o-light flashlights. non conducting, even a multi meter said nothing - avoid

Works great with an Acebeam E70 and 18650 battery
but pricy for what it is. Seems well made and robust enough for long term use. Limited choice on these adapters so went with Fenix, a known quality brand.
