After 3-4 days on the forum, I would like to say that no one told me I was joining a group of rocket scientists! lol They didn't tell me there would be math... they didn't tell me I would need to be an electrician. I don't know what volts and ohms and mAhs even are!

So for those of us who couldn't balance a checkbook, even when we used checkbooks, please... for the love of vaping... tell us what setups we can use without hiring a tutor or buying a new calculator.

Please. For the love of vaping.

I assure you, there's no need to get caught up in ohms, volts, amps, watts, and milliamp-hours. If you get even a halfway decent tank/cart/atty/clearo/whatever and a vv mod, you're well on your way to getting a great vape. Even if the mod displays volts and watts, just keep toying with the settings until you get a vape that pleases you.

If you want to learn all about volts, watts, ohms, mAHs. You are in the right place it's easier than You might think.
If You don't want to learn these things and do have a variable watt/volt, just adjust to what ever tastes/feels best to you.
Here is an Ohms Chart ,that has the math already done for You.

Hope u have a degree in chemistry to mate, lol

lol You're just mean

I do admit to watching a few conversations about DIY out of the corner of my eye and that's probably not too far in my future. I'm a much better cook than electrician. Frankly, I'm not entirely sure why the lights come on when I flip the little switch but I make a mean homemade chili.

LOLLLLL although quite large I LOVE my Vamo for that exact reason. Set it to wattage (once I know the wattage I enjoy) and the Vamo automatically figures out the voltage regardless of the ohms.
Once you figure out the ohms+ volts you enjoy use this calculator to figure out the wattage.
Watts - volts - amps - ohms conversion calculator

Somewhere out there
Solution #1 - Get a Smokeless Image Volt or a Bloog, buy their cartomizers and don't worry.

Solution #2 - Get an Ego twist or Vision spinner along with whatever tank strikes your fancy. Set the dial to the lowest number and turn it up a little bit at a time until you like the vape, if it begins to get too hot and harsh, take it back down a notch or two.


Oh, and mAh is how big the battery is and how long it may last (hours of vaping).

Math! No mathe involved well maybe a lil' :lol:


The ratings 650mAh and 1000mAh do not state the maximum current output of the battery. Rather, they state how long the battery will last given a particular current draw. For example, a 650 mAh battery can deliver 650 milliamps (0.65 amps) for one hour. The 1000mAh can deliver 1000 milliamps (1 amp) for one hour. So, if you're using a 3.7 Volt 1000mAh battery, it works out like this:

I = current (amps)
V = voltage (volts)
R = resistance (ohms)

3.7 volts across a 1.5 ohm atomizer:

I = V / R

I = (3.7)/(1.5)
= 2.47 amps = 2 470 mA

This is the current that the atomizer will draw from the battery. To find out how long the battery can deliver this current, you do the following:

time (hours) = mAh/mA
= (1000)/(2 470)
= 0.405 hours

Therefore, with a 1.5 ohm atomizer, a fully charged 1000mAh 3.7 volt battery will last for 0.405 hours (24.3 minutes) of constant use.

Separating this 24.3 minute time frame into 5 second "draws,"

24.3 minutes * (60 seconds)/(1 minute) = 1458 seconds

1458 seconds * (1 draw)/(5 seconds) = 291.6 draws

You can do your own math based on how often you tend to take a draw to determine how long it will last you. My own personal experience is that, with a 650mAh 3.7 volt battery, using a 1.5 ohm atty lasts me about 24 to 36 hours while using the standard 2.2 ohm atty lasts me about 48 to 60 hours."

What could be more simple. You really don't need to get into all this math. A simple ego battery with low resistance (1.5-2.2ohm) stuff should work fine for most people. You only really need to get into the math if you are searching for the perfect vape. For the most part this is a fool hardy search that should only be undertook if you plan to make vaping a hobby. For me math was really easy and fun so I kinda got dragged into this search. :facepalm:

LOL! I know, right?

If I put a tank on something and it tastes too light, I turn up the number thingy. If it's burnt, I turn down the number thingy.

Hahahaha... my shortcut is that if I'm using VV, I add 1.5 - 2.0 to the OHMs that the atomizer shows and start there. Different juices I like at different settings... You get used to it after a while, but you also just kind of learn what works with what juices and don't think too much about it after you get going.

Oh great Baditude. Now he/she has to carry a chart around. I bet you have one laminated in a wallet card, yes? :laugh:

I hate charts.

Basically standard ohms for standard volt ranges (3.2 to 4.0 ish) Lower side of that volts can use LR stuff too.
Higher ohms for higher volts. (I used 5 volts for 3.1 ish ohm stuff)
Lower ohms for low side of the volts (3.2 to 3.4)
