Portable charger for 21700 unprotected

[admiralburns]

Hi folks,

Just a quick question, I just got a Zebralight SC700d and I'm using (unprotected) Samsung 21700 5000 mAh batteries. I charge them at home on a Nitecore charger. I'd like to have a portable option and my only portable charger is an Xtar MC1, which does not list compatibility with 21700 batteries.

I'm thinking of buying a FourSevens Flex for use when I travel. Can anyone advise whether that portable charger would be safe and effective with unprotected 21700 batteries?

Thanks!

Burns

I use that same Flex charger for chonky batteries that don't fit in my charger, like a 26350. It does a great job.

Xtar lists that a Flattop 21700 fits.

The nitecore LC10 can hold up to 21700. And I finally found the one i use, folomov a1 magnetic charger
