As most of you know I got a provari recently and wanted a solid small VV box for excursions with the wife and family and I just got my Kens Big brother VV box and it works like a champ. On the meter all the settings are working perfectly. Good solid vape. Any of you guys know what vari cool means? I still have no idea haha..

Vari Cool is most likely a variance of the term used to describe the regulator. One of the first modders that I know of to use a switching regulator called it an Evercool and the term has stuck, it's still a popular thread in the modders section.

Switching regulators are more efficient than linear which means the don't waste as much energy as heat and the batteries last longer, vari and evercool just means they are using one.

Nice mod, I've had the non very version as well as the lil sis, Ken does great work.
