Why should I vape with high resistance?

[yanivriz]

I know that the power/heat over a resistor, is V^2/R.
Thus, there shouldn't be any difference between using an LR with low voltage, or a high resistance with high voltage.
If so, while knowing that higher voltage=less battery time, why should I even consider using a reg/high ohm coil?

You are right! I vape with LR cartos at the lowest volts on my VV devices.... Knocks my socks off .

Not always, your batteries are rated in mah (millampere hours), so how long it lasts depends on how many amps you're using over time to produce the vapor.

2 ohms X 3.7 volts will give you ~6.8 watts (the heat) and use 1.85 amps BUT
3.6 ohms X 5 volts will give you ~6.8 watts (the heat) and use 1.39 amps to produce similar vapor.

The watts make the difference in what you feel in the warmth and quantity of vapor, both high and low resistance can provide the same, (dependent on voltage) but will use a different amount of amps to get there.

edit:
p.s. if you carry a spare battery, either will work, so long as the watts are equal..

thanx!
great answer.

For me, I like 5v better. It seems to carry more flavor as well.

Not exactly , you will be giving 5 Volts to the carto but the battery still only produces 3,7 volts or so . To boost the voltage you have to draw more amps .

Actually I think that the most efficient way of producing a given wattage would be to take the volts that the battery supplies and a Low resistance cartomizer with no circuitry to boost the voltage and waste energy.

I use stacked protected battery box mods with a voltage regulator. lol. 100% consistent voltage. Hits the same all the time. If I had one with a switching reg, it'd be even more efficient. No booster required.

Voltage = oomph. OK, so you can get the same watts with LR. It's fine too. Nothing wrong with it. 5v or VV just seems to "work better" for me. Also I think the atomizers hold up better for higher ohm stuff (although atty quality varies a lot to begin with). Think of it this way... to get LR you have to have either a shorter wire or a thicker wire. Shorter is probably more common. So..smaller hot spot even at the same watts. Surface area of the coil has to come into play here somewhere.

My first idea was that the taste is different, for the same watt on different ohms.
but I couldn't have a good idea for the reason behind it...

one idea that passed my mind, was that high ohm coils warm up faster, so even if the watts are the same, it could be explained by the time its take it to get to targeted wattage...

Exactly! Just like cooking with a bigger heating element on the stove.

With LR at the lowest voltage you have no room to change the heat or flavour . A LR carto even at the lowest voltage maybe still too warm for some . The lowest voltage on the provari use to be 3.3 volts on the V1 now it is 2.9 volts to accommodate those who use LR . AT .1 volts increments you can adjust up or down to taste or juice used if you use SR or HR . Also as the carto wears out you can still adjust up as needed . I think one thing that shortens the life of a carto is using a bit too much heat . It is good for a while but the carto does not seem to last as long .

The only difference I found in vaping LR with low voltage and HR with high voltage is batt life. I get much more batt life when I use a 3ohm carto at 5v than when I use a 2ohm carto at 4v. I have a few 2ohm cartos left over from last year and I'll use them up but I never buy 1.5 or 2ohm cartos anymore. Everything I buy now is 3ohms. LR and dual coils are hard on my batts and I can tell a difference in batt life. all of my devices (that I use anymore) are VV, so there's no need to buy LR stuff. (Unless I was to get a super cheap deal LOL)

Oh. thanks for the tip. My cartos last for 3-4 weeks before performance drops (although I vape on at least 8 at a time). I don't know if really I want them to last as long as my EMDCC's that last for 6 months until I finally throw them out because I'm bored with the flavor.

How long should a carto last?
