    @Asbestos4004 That's all I was trying to say for the second half of this thread - I probably didn't explain myself as succinctly as you just did, but I quickly realised that 22g wasn't going to do it with the airflow available in the DotMod - and I was very happy to go back to the 24g build -...

    I know how TC mode works - I tried to get a little more vapor production by trying the 22g coils - it's TC mode so I don't expect it to reach my max power setting, but the coil mass increase from 24g to 22g meant the coil was staying to hot - the power was not being applied - and I didn't have...

    It's not a mystery - IT'S THE AIRFLOW

    Absolutely right - if I turned the TC up to 550F it would chuck a lot more power into the coils.

    Yes you are missing the point, but don't worry you seem to be in good company. With the watts set to 140watts and the TC set to 430F this build was teaching 430F in about half a second and TC was kicking in and reducing the watts to the 60w to 70w range - IF I HAD MORE AIRFLOW THE COILS WOULD...

    ... It hits like a freight train at 90 watts but it's too hot a vape for me. At 100watts it was popping like a Tommy gun. Didn't taste good at all. At 120watts it tasted of burnt sugar - horrible - that's as far as I'm prepared to take it. There was no point at which it tasted as good as the...

    OK - fine, I'll do it if it will make you'll happy, I'm off to vape the 22g in Power Mode.. ... I'll be back :)

    Hi Anna, I thought I had gone to some lengths to explain why I believe the power limiting to be a product of insufficient airflow for the 22g build. Here's a picture of a Dotmod RDA - it might help explain what I'm talking about. I could be wrong. If someone provides a better explanation I'm...

    No, because it won't increase the airflow.

    The only thing that matters on a regulated mod is keeping within the amp limit of your batteries. Power \ number of batteries \ minimum voltage of batteries. The 140watts I had set: 140watts \ 3 batteries \ 3.4v cell cut off = less than 14 amps

    Hi @-KT- I mentioned that the DNA250 is well within specification to provide 250watts to this coil in TC mode. To my limited understanding it is the power (watts) that get the coil vaping. Yes they are a result of a combination of volts and amps, but I don't see volts being a significant...

    Which brand and model of 18650 battery?

    Personally I go with the LG HE4

    Hi @Eskie - I'm using a DNA250 it's rated to 0.05ohms at 250watts in TC mode. The mod is the Tirade which is a 3x 18650 in series mod, so I'd be surprised if it's a raw power issue.

    So I went ahead and installed a: SS316L, 3mm ID, 6wraps, 22g, Dual Coil @ 0.09ohms I kept it at 430F but pumped the max power up to 140watts - and something interesting happened. The TC refused to put more than 70watts through it - a little less power than it puts through my standard 24g...

    Changing my coils daily. Getting frustrating..

    Seems to me that the three major factors are juice, power and ml. Unflavoured juice keeps your coils and wicks clean for long periods. Dark coloured sweat flavoured juice runs amoke with them. At 35watts I was getting through 40ml of flavoured juice before needing too change coil (for me...
