What's the difference in vaping voltages?

[STLBluesNut]

I have a question about the difference in vaping at different voltages.

Per a chart posted in the Lavatube forum:
-1.8 ohm atty/carto at 4.0v produces or uses 8.8 watts.
-3.0 ohm atty/carto at 5.0v produces or uses 8.3 watts.

I suppose I am misunderstanding what watts represents here as the heat/power generated/used by the coil. So why am i getting the impression that vaping at higher volts but higher resistance is a better vape if the same amount of heat/power is generated/used by the coil? By my understanding, or misunderstanding, using the higher voltage will drain the battery faster?

Sorry if the question is unclear but I'm sure someone will understand =p. Basically sell me on why some posters believe the vape is better on a 3.0 vs a 1.8 ohm atty/carto. I use a 1.8 ohm atty on a lavatube between 3.8-4.4v. Why should I get a higher resistance atty/carto?

LR cartos generally load an unregulated device very quickly yielding a fairly narrow actual range of voltage adjustment. Meaning that if you set the voltage higher than what the device can deliver and maintain for the carto's resistance, you aren't actually getting an increase in power (difference in vape). A SR or 3 ohm carto will permit a greater range of voltage adjustment before the device runs out of gas so to say. So for that reason, it is believed that the higher resistance cartos are a better choice on devices capable of going up to the 6 volt range.

Also keep in mind that lavatubes and some other vv PVs will regulate the wattage. So a LR carto or atty won't be allowed on a lavatube to go over a certain voltage (for instance my standard dual coils which are 3ohm but combined (meaning each coil is only 1.5ohm will only allow around 4.0 volt max)

AttyPops explains this very well with an automotive comparison that goes something like this: Can you do 85 mph on the interstate with a 1977 dodge colt 79hp 4 cyl? Sure. Can you do 85 mph on the interstate in a 67 camero with a 300 hp 8cyl? Yes indeed. Which one is more likely to get you to cruising speed faster and smoother?

Most of what it comes down to is these two items: - How fast does the coil heat up to the point it can overcome the the mass around it and the temperature of the mass around it (carto filler - or ceramic - or juice - or etc) to get to the point it is at optimum performance? - And, how much nichrome wire is there in the coil for surface area to vaporize juice with? And, I suspect that in many if not most cases, the surface area has more to do with it than anything else.

Nichrome is rated at ohms per inch. Now, there are a lot of different ratings available so it is indeed possible to have two different pieces of wire at the same length to create very similar ohms of resistance... but in actual practice, it is unusual to see an atty/carto manufacturer deviate very far from just one or two ohm ratings of wire in their inventory. So, more often than not, a company that makes a 1.5 ohm, a 2.0 ohm, a 2.4 - 3.2 - 4.0 or etc ohm atty or carto uses the same nichrome wire for all of them. So, the coil surface area of a 3.0 ohm coil is twice as much wire as their 1.5 ohm version. More surface area to create vapor with can mean a better experience (and often does... but in my experience not *always* does).

+1.

I'm figuring this out now, I've been using 1.7ohm smok techs on my lavatube. It vaped great, but I suspect better when I am able to snatch up some 3ohm cartomizers.

Thanks for the replies. Makes sense. Especially the surface area.

Last thing tho. Will the higher voltage, even tho wattage is similar, drain the battery faster?

Actually it normally makes the battery last longer because even thought the same wattage the amperage will be less.

All the above are great answers. Yes...micro volt adjustments, surface area, batt life, etc.....

As an FYI...I created that chart (actually, originally I made it years ago, for my apprentices to learn and understand loads, wattages, etc...for work, we are Electricians), but when I got into vaping, I modified it again for my own use.
As we know, the ohms of a particular atty/carto varies even though it is listed as a cetain one...ie...a 2.0 ohm listed can actually be anywhere from 1.7-2.3 ohms. Those micro variances in ohms affect flavor, TH, clouds etc...on the same battery.

Having made the chart, I was able to organise all my gear to match certain juices etc...for personal use. In a way, I was making my own VV ability on the cheap.
I now have all manner of gear.... boxmods, Infernos, eGo's, Pro Vari's, SB, Kicks, Bolts etc....and I still buy most of my accessories in the 2.0 ohm range. This is simply because it allows me to minimise some stock, and still get a great vape on whatever gear I put them on. I run 12+ setups daily at any given time...

Back on topic...but when the LT was coming to market, some friends in the Volcano forums asked if I could make it avilable for all to use...and I was happy to oblige.

Again, like in the legend....it is just for reference...only you can decide what you dig the most.... LR setup, standard, HR .....
