Presently, the mini Protank does not have 510 threading and will need an adapter. I've been stalking the Internet to see when Kanger will release their 510 threaded Mini PT for another mod I have. (I read that there is a plan for it just don't know when). I absolutely love my mini Provari! Good choice. Usually I use my PT2 with it because of the juice capacity when out and about. (and today I just made my first successful rebuild of the coil!) Enjoy!
