Grenade Mech Mod 1st Look – S100 by Eternal?

10411326_1625518257673218_2446965732120738951_nDuring my visits to Brick and Mortar Vape stores in Birmingham, Alabama yesterday, I came across this grenade mech mod. I had to have it. The thing is, I don’t know anything about it really. The owner of the shop says that it’s made in China and only sold through a vendor in Canada. I walked out with a black version, but they had two other colors available, green and bronze.

When I got home with it last night, I started to dig around to see what I could find. I ran into a dead-end pretty fast.

Other than the images on Fergy’s Vape’s Facebook page, all I could find was a Twitter account pimping this product.


On this Twitter profile, I found the email address and the domain was I poppped the url into my browser and it’s a website for a company in China called Eternal. I couldn’t find anything on the website about this product though. I knew I was in the right place because the models they do have listed on the site look like the image I have posted in the top right of this article. The model number printed on this grenade mod is S100 and there is a model number of another mod on their website that is S80. Anyhow, that’s all I know about this mod a this time.

I posted a thread on Vaping Underground and so far, nobody else knows anything about it.

UPDATE: I found information thanks to a Facebook comment from Dee Lynn Quint. Thanks!

It’s called the FITH Mod and there are reference to the Innokin Cool Fire 2 in several places on that page, even though it looks nothing like  Cool Fire 2.

The connector has both eGo and 510 threading. With a tank like an iClear 16 or Aspire BDC, the base of the tank ends up with 1/3 to 1/2 inch being covered. It doesn’t affect airflow too bad.

This mod has a tube that only allows for an 18350 battery like the one pictured on the right.

My 1st Impressions are good. It feels awesome in the hand, it’s quite solid too. There is no battery rattle and it’s fired everything I’ve thrown at it so far.

Here’s a quick video 1st look at this device:

If I learn anything else about this mod, I will update this post.


  1. I have these in stock. You can find more pictures at:
    I am in gardendale Alabama. I deal directly with the manufacture. As with any 18350 mod it will do clearomizers of any type. I do not recommend drippers as well all know 18350s do not last well. I do not sell the pretty packaging because I got these in well before the package was designed. I sell the body only.
