I am lost, whats the point of high ohm?

[AttyPops]

I can honestly say I've never got an hour of vaping per 100mAh. Might get there with a 3.0v battery and 4.0ohm carto...

Yeah. I think it came about as a rough estimate mostly because the numbers are easy to work with and it's a total crap-shoot anyway. lol.

Device efficiency varies a lot. So do vaping habits. So do setups. SO DO batteries (the mAh ratings...they LIE LIKE RUGS on some of em.)

I almost never quote that "statistic". Or I have to type 5 posts explaining it. ( bad)

I currently vape at 1.8 ohm as well... a higher resistance means it is heating the liquid to a higher temperature.. I just triend a 2.4 ohm at 4.2 volts and I got quite the cough from the hit.

No. Higher resistance = lower temp than a lower resistance AT THE SAME VOLTAGE. But if you changed the voltage, you changed the equation.

Watts = Voltage squared divided by resistance e.g. P = V² /R

This would be true with a constant current source, but it's backwards for a standard or VV battery. Raising the resistance lowers the current. Since heat produced is equal to the current squared times the resistance, higher resistance produces less heat.

EDIT: Oops, AttyPops beat me to it.

I understood the gas tank explanation.
So the "hours" you are talking about aren't 60 minute hours, Which are the hours i understood you meant, but a different kind of hours altogether.

What AttyPops said.

I won't go so far as saying the mAh rating of a battery is worthless, but it can be highly deceiving. Brand makers such as Panasonic and AW will give more realistic mAh ratings, but lesser brand makers are well known to exagerate the mAh rating to push sales.

Factors such as how frequently you vape (chain vaping vs occassional drags), quality of the battery, the resistance of the delivery device, the efficiency of the booster circuit processor (if any), etc. all come into play. It's simply to be considered an "average", folks. If you are a heavy vapor there's no way you are going to approach the listed mAh.

Also keep in mind that the batteries that we use in our PV's were not specifically designed to be used in this application. I tend to think we can push our batteries a little harder than what a simple flashlight demands.

Someone who created the Safe Vaping Power Chart wrote an article explaining how using different resistances and voltages can improve your vape and help you find your "sweet spot". It may help explain your questions.

I'm curious, if 3.5-8.5 is the ideal vape range, why do up to 15 or 16 watts? Are there any devices out there that don't just melt over 10 watts?

Hi, thanks for all your replies. But you keep talking how high voltage permets higher ohm carto does not explain why people want to go for it, I need more feed back from the point of view of vaping experience. For those who runs high ohms, why would you do it, does it bring better flavor? more vapor? stronger hit? or you are just doing it so your bettery will last longer and your carto will get longer life?

Some hard-core vapors like vaping on a power torch?

Personally, I can't see it. I prefer a cooler vape so I use 3.0 ohm single coil carts and rarely use over 4.8 volts, so that's not even 8 watts. Even with my RBA's, I use a 2.0 ohm coil. No SLR for me.

For me personally, LR atty's have too warm of a vape for my preference, no matter what voltage is used. It appears harsh and can be uncomfortable to vape. It can also make some of my fruit flavors to taste burnt.

The higher resistance coils are cooler, not as harsh, and to me bring out more of the flavor in the juices that I use. I also like having the option of using a coil specifically designed for use at 3.4 - 5 volts, which is the voltage range that I use with my Provari's.

This is based purely on my own experience. Your results may well be different from mine.

To me....higher voltage stuff reacts faster. More like hitting a cig...to a point. You don't want to over-do it. That said, the slow-to-glow of lower voltages was different. And the LR stuff on 3.x voltage....I have the same opinion as baditude on that...it's kinda hot and just...not as good flavor wise. Those LR (1.5 ohms or 2.0 ohms) on the 3.7 stuff was just kind of a "small hot-spot coil" feeling that I got from it. It was hot...but in a small little coil. This was with stock stuff.

Now with the RBA stuff, and the differing gauge wires...people experiment with different things. So I think the wire they used in the stock stuff ...made a difference too. Particularly for the 1.5 ohm coils on 3.4 volt eGo units compared to 3.1 ohm stuff on 5 volts. The 7.7 watt stuff (1.5Ω on ego) was harsher than the 8-ish watts at dedicated 5 volts. That was all "back in the day" before VV. Now I can tune my vape at bit with VV.
