Nice video i have been using dual coil smoktech on both of my provaris at anywhere between 4.5-5v with no errors... They are the smoktech dc cartos from madvapes and i use them with the madvapes 5ml
tank...my provari gave me errors with the 1.6ohm carto that came with the
tank...but the 2ohms work perfectly at 5 volts..carto reading after 5 constant days of
vaping at 2.1ohms
