    Works as advertised - be aware, it is bigger than 1st Gen(?) 21700's. I have to force it into my nitecore I bought back in my 16850 days...it's slightly fatter and longer. Ordered an Xtar 4 slot(on site) charger with a second 21700.

    I love these batteries and they work flawlessly in my Nunchaku 2, but they are too large for an Innokin Plexar.

  8. Top of the line 5 Star Review

    Posted by on Apr 24th 2019

    Cant by a better size and brand than this 21700, I only wish it was compatible with more of my mods. Its night and day using this over a 18650. I now specifically shop for vape mods that use these 21700 batteries, rather than shop for my mod and then find batteries that fit.
