This has been discussed many times and I saw the chart already.

My confusion is:
- the chart is saying that basically you should use lower wattage or power to vape lower ohm
- but my friends who use kayfun and other rta, was using 0.5-1 ohm but vaping at 20-30 watt.

They are saying that I need high watt to vape low ohm and would be useless to use, say vamo v5, on a kayfun cause it doesn't have high wattage setting besides it only accepts 1.2 ohm anyway.

So which one is correct?

Thanks.

I don't know which one of those charts you're referring to, but they're all about the same, and pretty obsolete. They were mostly developed when everybody was using some sort of cartomizer or clearomizer, with their tiny coils, and very limited air flow. Modern devices, whether they're RDAs or RBAs, have much larger chambers, bigger coils, and much more air flow, which allows for vaping at wattages unheard of a couple years ago.

I don't know about batteries but I hear ppl saying when they vape lower volts , it's lower watts too? That makes no sense. watts and volts have nothing to do with each other in that sense. Watt is a measure of quantity, while volt is a measurement of flow. A 1000w light running at 120v is 1000watts...a 1000watt light running on a 240v is still 1000watts but it will save electric because the flow is faster so to speak. A 400w light at 120v is still less power and light than a 250w light running at 240volts.

So the low ohm will draw more amps from a battery so that is where the high watts and low volts come into play. Just to clear some things up.

watts = volts x amps

So, if you have a specific resistance and a VV mod, when you lower the volts you are also lowering the watts.

Also, amps are a measure of flow. And volts are a measure of electrical potential.

woe! increasing voltage to 240 would give you 4000 watts.
Watts - volts - amps - ohms conversion calculator
i think you mean 1000 watts power total being used is still 1000 watts.
when you say a 1000 watt bulb that's the rating of the bulb at 120 volts.
if you increase voltage you have to increase resistance to maintain the
desired wattage.
volts are a measurement of pressure. current(amps) is the measurement of flow.
watts is volts time amps,the quantity of power being used.
resistance determines amperage at any given voltage.
voltage divided by resistance = amperage.

Thanks for that. So I have a twist vv battery that is 11 watts. So it is only at 11 watts when it is cranked up to 4.8volts. This makes sense now. That is why it's takes large batteries to sub.

I think you meant volts x watts= Amps though

You will only hit the full wattage specification at the highest voltage setting.

And no, I meant exactly as I previously stated:
watts = volts x amps

Also,
volts = amps x resistance

Not large batteries in particular, but it is why safe continuous amp discharge is an important measurement when talking about batteries.

As you decrease your resistance at the same voltage, you increase the amp draw. So a simple 2 ohm build at 4.8 volts will be pulling 2.4 amps from the battery. That same 4.8 volts on a 0.2 ohm build will be pulling 24 amps from the battery.

This is why batteries have cut offs preventing firing below certain resistance. The manufacturers know the limits of their battery and prevent people from firing builds too low.

Hi, it was the chart with red, yellow and green color which the green color says that it's a perfect vape Volts / watts.


Thanks for your explanation though, the modern device then made the chart obsolete...

I just thought because my friend says it's too much for me to vape aerotank mega 1.5 ohm with 12 watts while he was vaping a Kayfun 1.0 ohm with 23 watts... I thought it was inconsistent for him telling me that lower ohm needs lower wattage... But maybe he meant that because I am using aerotank mega not the kayfun

Here's the chart you're talking about:
eKX39cgATALYlRmrfVn7fxGqhQVc4Fx4_Lo0AVE6jyeoVxuoBqDV--KqypXxFD5MjqGzIQ=w1061-h741

The problem is, it completely ignores one of the most important factors, which is the temperature of the coils. This is determined by how the wattage is spread over the coils, how the wicks are set up, and the airflow around the coils. A very small coil with low airflow that is poorly wicked will burn the juice even at a low wattage. On the other hand, a multi-coil build with low gauge (thick) wire, in an atty that has good airflow and is properly wicked with good juice flow will be able to produce a lot of vapor without burning the juice, even at a high wattage.

The difference is he is probably using a heavier guage wire on his Kayfun. Those charts were made during a time when there were only single coils, and they were all made with 30-32 ga wire. Dual coils and heavier guage wire negate the charts, by allowing more power to flow through a lower measured resistance, when in reality it's much more coil, so more power is needed to reach the same temps.

Those charts are NOT obsolete. They are a Starting Point.

What you vape at and what I vape at are totally different.

It all depends on the thickness of the juice, the coil resistance, how that juice is wicked to the coil and air flow to the coil along with if you like a warm to hot vape or a cooler vape.

when it comes to the gauge of the wire how much increase in diameter is needed to offset
the amount of heat produced at a set resistance and voltage. am i right in thinking if one uses
2 different gauges but maintains the same resistance the lower gauge wire would need more voltage
to maintain desired vapor production because of the gain in area?

Vapor production is related to power in Watts, which is volts times amps. For a given voltage and a given resistance, amps will be fixed, and thus the total power to both coils will be the same. So, they should both produce around the same amount of vapor. However, the bigger coil with thicker wire will produce less concentrated vapor at a lower temperature, from a larger surface of wick, while the smaller coil with thinner wire will produce more concentrated vapor at a higher temperature, from a smaller surface of wick. The higher temperature juice may taste different, and may even taste burnt. Plus, the coil size will also affect how well the wicks work, and how well the airflow around the coil works to draw vapor away from the wick and to cool the coil. So, the final vaping experience can be quite different, even though the total amount of power is the same.

Your friends are dumb in regard to the Kayfun. A lot of people use a Kayfun at 1.5 ohms @ 10-15 watts. PBusardo himself runs 1.4 ohms and about 14 watts on Kayfuns. I run about 13w on mine.

A Kayfun is not really about sub-ohming, though you can certainly do so. If you really want to subohm, a dripper is probably best.
