Those of you that have been vaping for a couple years probably remember the Protank line of clearomizers from Kanger. They were great devices at that time and Kanger is continuing the Protank Line with the release of the Kanger Protank 4. This tank uses the same SSOCC coils as their other tanks but it also includes RBA section with a velocity style 2 post deck. It comes pre-installed with dual clapton coils. Filling this tank is simple through a sizeable hole at the top on the side that is exposed when you unscrew the top then slide it up. It’s great to see an old name make a strong comeback.
