Hi newbie here and I need some help...

[HardCoil]

Its the mod. He has a mod that does not has a step down so the mod fires it as true voltage. So if u have fresh batteries in regardless of what wattage u set it will fire at 4.2 volts so say the mods resistance is a few .3-4 ohms the voltage drops maybe around 3.8-3.9v. So at .2 ohms the mod is actually firing at 72watts! Hence the heat. I do not recommend anyone from getting the D2, its chip has a flaw. No stepdown. For u on the other hand i am sensing that the tfv4 might have better conductivity because of the material used to make the atty, hence the heat difference. More metal, more robust much more time to heat up. The atty warming up isnt a concern unless its too warn to touch comfortably! Rest assured the jumping ohms is from the difference of the resistance in every regulated mod. The smok might have much lesser technicalities and better wiring capabilities hence the lower ohms. The mod is not reading only the atty fyi. The mod is showing the full circuits resistance. Different mod different ohm reading and different ways of firing. Thats why when we use RBA rebuidable atomizers, tank atomizers or rdas rebuildable dripping atomizer we have to have our own ohm checker to check the ohm readings on the coil..

There was a time the coil i built read 0.09 ohms but it read on my ipv4s 0.11. This electrical stuff is kinda tricky, takes some digesting to really get the feel of it. Ask anything everyone is here to help.

Edit* also i would suggest to invest some time in rebuilding too. Get a basic understanding of ohms law and start rebuilding. No pressure lol. Just that to me its such a waste of money buying the occ coils and also most of them are duds and most of them fires at unnecessary wattages. You will be surprised once u FOUND ur ideal vape.
