What's the point to have different resistance heads?

[Shur]

New with mods and question is why is different resistance heads exist? What's the difference for example between 1.8 and 2.5 ohm?
Thanks.

1.8 is better for batts you can't change voltage on.
2.5 is better for vv batts that can be adjusted.

Why 2.5 is better on vv devices, i prefer 1.8 in all my vv/vw mods.

its all a matter of personal preference, try them all. you dont know what youll like until you try it

not that it's better, it's more like it doesn't matter because you set what the power output is. The PV will adjust itself to make that output power.

Need clarifications:
1) What is vv/vw? I have it on my eVic - but still don't have time to find out what is what
2) Why it's better that way?

Thanks.

It comes down to taste. I noticed that when I vape certain juices, I get a different flavor when using low or high power. If you have a variable voltage device, you can increase the volts or watts or decrease, until you find a nice combination that tastes good to you.

On devices that don't have adjustable volts or watts settings, you have to rely on the resistance of the head to provide a certain power. So for a device like an ego, which has a set voltage of, lets say 3.7, you would vape at higher watts with a 1.8 ohm resistance, than you would at 2.5 ohms.

The formula used for calculating watts or volts is: (voltage * voltage)/ohms = Watts.

So for a 3.7 device running at 1.8 ohms, you would be using: 7.6 Watts
Same device at 2.5 ohms would be: 5.48 Watts

If you try the same juice in both resistances, you may find that you prefer one ohm setting, to another, on a device that has no variable settings.

VW is variable wattage. VV is variable voltage. if your device does VW you set the power out...10watts. with the VV you have to do a little math and ohms law to achieve the 10 watts you want to vape at.

 

[E_DeCastro]

on genesis tanks that I run at about 1.8 ohms, I have to vape at 8 watts or I get burnt taste. on my protanks and the like I vape at 10 watts. it's all based on YOUR taste.

The different ohms resistance heads provide a different vaping experience. I will use the ego as an example. 1.8 ohms on a standard 3.7(ish) ego battery will give a warmer vape with a harder throat hit, but really shouldn't be used above the lowest voltage on an ego. The 2.5 ohm head will give a cooler vape and less throat hit on a standard ego voltage, but with a vv device, you have the option to raise the voltage. The basic rule of thumb is use voltage that is about 2 greater than the resistance of the head of the cartomizer.

The 2.5 will allow for more adjustment up or down on the power settings allowing a hotter or cooler vape.

The 1.8 at any set power level burns hotter than the 2.5 at the same level.

The 2.5 will allow for cooler vapes than the 1.8 AFAIK(correct if I'm wrong.lol)

Ohm's Law Calculator

Check out the amperage used for each resistance at a given wattage or voltage. Then think about the mAh of the battery you are using, and the length of time the battery charge will last.

It does matter. The higher the resistance the more time need to heat up. I like better the lower ohms just because of that they heat faster. But yesturday a build a coil for my RDA and endup at 3.3ohm very big coil with 4x 3mm wicks inside thw wraps and lots of coil to wick contact, i takes longer time that what ive try but that huge coil is putting out a category 5 hurracane enormous cloud of vapor and fully saturated, flavor and throat hit is the best i have try, but i dont like to take a hit with such gradually heating up, is a very long drag. So diferent ohms will give you diferent types of vape,

I liked a lot my 3.3ohm my my next build i will try to lower that

At the end of the road, if you have a variable wattage device vaping on clero or cartos just buy any ohm availableand dont crack your mind with that, the range for replacement heads are from 1.8 to 2.8 so a new vaper wont feell much of a diference, i always try to get 1.8 but is not available a grab 2.2 or 2.5 cuz my clero will vape good anyway

LR (low resistance) = 1.5 - 1.9 ohm : Will provide a warmer vapor. May be harsh to some vapors and may burn some flavors. These were originally designed to simulate higher voltage in single voltage battery devices.

SR (standard resistance) = 2.0 - 2.4 ohm : A slightly cooler vape. Smoother than LR and may provide better flavor production with some juices.

HR (high resistance) = 3.0 - + ohm : Intended for variable voltage/variable wattage battery devices. This resistance will allow full range of voltages from 3.4 - 5.0 volts.

The "Safe Vaping Power Chart" can be helpful for new vapors to decide what resistance is best for their battery device.

Thanks everyone for replies! Now i know
