Fenix ALF-18 Battery Holder 18650 to 21700 Adaptor, Copper

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

Very pleased can use smaller battery now , money saving.

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.

Bought these to convert 18650 into 21700 for multiple o-light flashlights. non conducting, even a multi meter said nothing - avoid

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.

Could be a little more longer but very useful

Did not work with 21700

Ürün iş görüyor, sorun yok. Çok çok basit bir ürün. Ama gerçekten çok pahalı. Bu fiyata 3-4 adet 18650 pil alınır yada 2 tane 21700 pil alınır. Almış bulunduk bir kere.

電池のストックを減らすために18650を21700として使用するために購入。 ランタイム減少とと接触不良の危惧は有りますが使用できました。 TK20R V2.0とTK25Rの2機種で使用中です。 数量限定?廃盤?の可能性があります。 必要なら早めに購入をお勧めします。

Se adapta perfectamente a la bateria

Ripeto, fa quel che deve..permette di usare batterie 18650 che sono più piccole delle 21.700 nella mia sigaretta elettronica
