Juice consumption at different wattages, ohms and volts

[JUMA55]

Consider this, same juice, Space Jam Eclipse:

Innokin MVP20W, regular Nautilus, 9 watts, 1.8ohms, not sure of volts

Innokin MVP 3.0, Atlantis 1 with new 1.0ohm coil, 15 watts, 3.9 volts

Innokin MVP 3.0 Subtank Mini with 1.2ohm coil but measured at 1.3ohms, 9 watts, 3.4 volts

The two units running at 9 watts appear to put out the same amount of vapor. But the Atlantis running at 15 watts appears to put out less vapor, although it is warmer and perhaps has a bit more flavor.

So I guess my question is are the two units at 9 watts consuming roughly the same amount of juice, whereas the one running at 15 watts is using quite a bit more? The airflow between the three is roughly the same. To put it another way, do watts and airflow mean more in the consumption of juice than ohms and volts do?

At the moment, it seems all the development is in sub-ohm tanks with the highest ohms being 1.2. I do sub-ohm a bit with an Atlantis 2. But for the most part I'm happy at 9 watts, 1.8ohms on the Nautilus. I'd like to have a few newer tanks, but I don't want to greatly increase my juice consumption for more modern looking tanks.

Thanks!

I have the Nautilus and it is a great tank. I also have the Kanger Subtank mini and use the 1.2 ohm coils. More power, more juice consumption. Vape at what your comfort level is, everyone is different.

Hi Juma. In general the answer to your question is yes. Generally when you run higher wattage it allows the coil to heat and vaporize your liquid at a faster rate.
That being said you are comparing across different tanks, with different heads so one tank may use more or less than the next solely based on that. Second to that the three tanks listed have different coil arrangements,different wicking methods as well.
The only way to know for sure would be to add equal amount of liquid to each tank and use only that one tank at one wattage until it is emptied while keeping track of how many puffs or total time from full to empty. Then follow the same practice with the other two.
I think that would be the best way to find out for sure how the three perform for you personally. Remember that everyone is different. Good Luck. Happy Vaping.

Wattage is equal to produced heat. Heat should dissipate. It can boil juice (producing vapor) and additionally it can heat air and atti. So, in most cases equal wattage should produce close amount of vapor, but because other things (air and atti) it may be not equal.

Its not the WATTAGE that is using more juice it is the SURFACE AREA of the coil.. 3 coils a 1 ohm each, 24,26 and 28awg which will use more juice????? Remember they will all be running the same wattage?

There's a lot of variables that influence how much juice you go through. Wattage is just one, and really not a very important one.

The three most important influences will be the size of the juice channel, the amount of wick, and the type of coil. A tank with a large juice channel and lots of wick running to a large diameter coil will use more juice than a tank with small juice channels, a small wick, and a small diameter coil, even if the ohms and wattage are identical. Airflow is also a pretty large factor as a lot of air allows for a lot of vapor to be produced while a small amount of air will actually choke off vapor production resulting in less juice being used.

Keeping this all in mind, your average subtank will use more juice than your Nautilus with wattage and ohms being equal. The Nautilus will have smaller juice channels and less airflow, so it's more limited on how much juice can reach the coil and how much vapor it can produce. If you start cranking the wattage up the Nautilus will start giving a burnt taste before the subohm tanks do, and that's because the coil is being choked off on both juice flow and airflow.

Good answers from all of you. Thank you!
