What effects e-juice consumption?

[Murgi Patel]

Hi,
I wanted to know what factors affect how much e-liquid is used in an e-cig, for example more airflow = juice used up faster? Or higher wattage more juice used? Or less resistance = more juice used up?
I have an evod twist and I wanted to upgrade to the ego one xl but I am afraid it will use up too much juice and I can't afford that much juice. I vape an average of about 1 ml a day on my evod twist and I vape for an hour or so a day.
Thanks in advance this will really help me

Also if anyone knows advantages of the ego one mega over the XL, apart from tank capacity and larger battery, please let me know. Does it heat up less or something?

juice consumption is related to how often, how big of a hit, higher watts, multiple coils, and give aways ( letting friends try it)
at 1 ml a day, thats rather low for the norm.... there are people out there that go thru 50ml a day
Heathers Heavenly Vapes sells 100 ml bottles for 40$ ... that would last you 3 months

if you are using throw away coils, your probably spending more on coils than juice ...

Higher wattage and lower ohm coils (which use higher wattage) use more juice. The eGo One will drink more juice than your Evod. How much more will depend on which coil you use. The .5 will use more than the 1. The difference between the two is size and capacity, nothing more. The Mega holds more juice and has a bigger battery.

Practically anything will use more juice than an Evod. It's a low powered rig. If the cost of juice is a deterrent, you may want to consider making your own. I do, for less than 5 cents US per ml. I spend a lot on vape gear-- I have shinyitis-- but not on juice. One other note: more power is going to make a bigger vape. That means you're going to be getting more nicotine per puff. You may want to cut that down.

Wattage is the main factor.

Heat and surface area. The more surface you have to generate heat on the more potential for vaporization you have.. The more juice supplied to the surface the more potential for steam... the more heat you applied to that surface the more the faster you can convert that juice to steam.

Thankyou all for the replies!

NO it is not.. Big difference between a big coil vs a small coil, than is putting out 25 watts..

Yes.
Big difference between a big coil vs a small coil.
The big coil has an operating range higher in wattage than the small coil.
Run them both at the same wattage, and the small coil would be hotter.

The question is about juice consumption.

What if the 2 coils are of the same OHM rate, they would then put out the same wattage. 25 watts at 1ohm is always 25 watts. Now a tiny 1ohm coil will BE hotter and the big coil will have more potential for heating at increased power levels than the small coil... Problem wattage is OUTPUT not INPUT. The small coil will just reach max temp sooner. FWIW the max temp is based on the material not so much the size. Kanthal melts at a specific temp. At that temp your wire will pop regardless the gauge.

The specific latent heat of vaporization of water, vg and pg are all in the vicinity of
1 kilo joule per gram.
that's 1 joule per milligram

1 watt is 1 joule per second.

So if you vape at 10 watts you can vaporize about 10 milligrams per second.
If you can increase vaporization by adjusting coil or airflow or whatever else, these adjustments are merely efficiency adjustments. You cannot get more vapour than can be produced by the wattage you put in.

Therefore the overall/major factor relevant to new vapers for understanding juice consumption is the wattage.

This assumes the coil is of a size sufficient to create the heat in the first place. a 1ohm 27awg coil is going to hotter at 10 watt than a 2x30 parallel coil at the same 1ohm and 10 watts, but 50% less surface area. I will agree the 30awg coil will need more watts to achieve the same wire temp. But don't think it would need as much heat to create more vapor. Because it will be heating more juice at a time, to begin with. FWIW the 30awg coil produce approx same heat at 18watts. At same OHM rate difference is surface area... This is the problem with associating watt level with consumption. Sometimes less watts is HOTTER.
