Ohm's vs voltage

[Evergreen]

Hi everyone,
I am looking to get some guide lines on what different people use for voltage VS ohm's. I do understand a lot has to do with e-juice mixtures but general settings would be nice. Example, I am hitting a 3 ohm carto at 5.3 volts which is the highest I have been at. I just got atomizer 2.5 ohm and hit that at 5 volts. Up until the last two days i generaly was at 4 to 4.3 volts. Any input would be nice. Thanks.

There's a guy who created the Safe vaping Power Chart that many people use as a general guideline for matching ohms to voltage and watts used. He also wrote an article on how to find your "sweet spot". The spreadsheet chart is included in this article:

Personally, I use cartotanks. I use a single coil, 2.5 - 3.0 ohm cartomizer on a Provari. I prefer using voltages of 3.4 -3.7v for fruit flavors; voltages of 4.0 -4.8v for some flavors like coffee; and higher voltages of 4.5 - 4.8 v or higher for cinnamon flavors.

in my searches it seems the hooded guy with sunglasses from pa offers a great simple math solution...wish I could remember the username...double the ohms and subtract .2 and that's your voltage and it should be a nice matchup...works for me so far!

Let's see... 3 * 2 = 6. 6 -.2 = 5.8! Holy burny crappy taste! Nice notion, but... I would advise against that. Ohm's law is rather simple and straightforward. Don't be intimidated or feel incompetent. Some (emphasis on some, as certain aspects can throw you off, but these should suffice with minimal confusion) comparisons can be made between hydraulics and electricity. Think of voltage as pressure, amperage as flow, and resistance as, obviously, obstruction to flow. A good rule of thumb is to find your watts or amps, since these are the end products of the equation we desire. So, at 3 ohms, I would recommend an amperage of 1.4a to 1.666a, which, in volts, comes to 4.2v to 5v. This comes out to be between 6 and 8 watts. I (amps) = E (volts) / R (resist). P (watts) = I * E. Thus: 4.2v / 3r = 1.4a or (*4.2v) 5.88w. and 5v / 3r = 1.666a or (*5v) 8.333w. Depends on the juice/mod/carto, but I find that much below this I no longer receive much in the way of vapor, flavor, or TH... much above, and I burn the piss out of it. *shrug*

Really simple calculations, bud. Good for your math skills, irregardless. In the end, your own tastes shall be your only true guide in all things, this no less than any. Happy vaping. Double emphasis on the happy.

*edited* for sense.

I am using a LR Carto of 1.5 ohm, so 1.5*2 is 3, 3-.2 is 2.8 volts. I don't know any device that goes this low, and my 3.7 volts works just fine.

hahaha thanks so much for the correction and info! and also with my boge 510 carto at 3ohms I have found vaping at 5.0 has been the norm for me lately...look at that!

the article was great and the chart may help me keep the volts down.

Numbers are not always the best way to calculate vaping satisfaction, they are a guide.

I coil .6 ohm on an Odysseus at 4.2v. That is over 23 watts--anything less and I am not happy.

Ultimately, it comes down to taste. Charts and math can give you a starting point, but then you have to experiment increasing and decreasing the power to find your "sweet spot," which often changes from juice to juice, and for me, throughout the day. I have one juice I like at about 6-7w in the morning, but perhaps 8w in the evening. The same juice also varies depending on what kind of delivery system it's in.

This is an ongoing debate that will never be answered here. Because everything is based Strictly on individual taste.
What some people swear by others will find lacking or overpowering.
so with that said there is no set rule of thumb.
Best rule is whatever makes YOU happy. And no one else. Start off at a lower voltage. Say 3.7 (close to mechanical mod) even lower say 3.4 for ego type vape. Check it out. Slowly increase your voltage. If it gets to a point where the vape is harsh or burnt. Well then you've gone too far. Then slowly back your voltage back off till you find "your" sweet spot. Then no matter what resistance your running...well guess what? That's where "you" like it..
its all subjective. A matter of where you like vaping

I am sorry, but this feels like your trolling us. But if that's what you like, it's what you like.

Don't worry about the extremes that some use. Instead think in terms of what the average vapor will use as a starting point. Then you can adjust from there to find the setting you like best.
Volts and ohms are only the means to an end, it's wattage that we end up with (also called "power"). Market research shows that the majority of users vape between 6 & 8 watts, but you need to understand that the type of equipment used can change that dramatically.
I'm lazy and use this:
Ohm's Law Calculator
I just type in the wattage that I want (say 8 watts for instance), and the resistance of the atty/carto/clearo that I want to use, and the calculator will tell me what voltage to set my PV at.

I vape the 306 atty's 1.5-1.7ohm ones at 4.2 volts on the provari
