Hi everone, first post here and I'll start off by saying that I am very new to vaping. Just 8 weeks in and I'm currently using a KR808D-1 set-up, but saving up for a Provari/tank combo. Really like the latter because it can read cart ohms as well as batt volage and my question is if anyone knows of a e-cig multimeter gadget that can be screwed in-line with 808 batts/carts that can read volts and ohms? Even better if it gives wattage. Thanks in advance...
