Hi, I have a newbie question. How do Watts, Volts or Ohms play in you vaping experience? Is it important to know them? Thanks

What are you using to vape with? Once I know this I can give you some links and videos to help you.
I just asked my friend what I'm using because I honestly don't know. He said I have and ATB box mod with vicious ant cyclone atomiser. The box carries 2 batteries and it has a knob to make the wick hotter. It also has a digital display inside that shows 3.23 when the knob is at minimum. Sorry if I'm not so familiar with my mod. All I really do is press the button and inhale. I have a lot to learn I guess. Thanks for the quick reply.
You do have a lot to learn.
Can you share what ohm the coil is in your atomizer?
Do you have an ohm reader?
What batteries are you using? Make, model, mah, and amp? (Using the correct batteries is extremely important.)
Lately, some of these threads are beginning to remind of the gun range. There are some people walking around with loaded guns and having no clue.
Great to see you Bad! I had to watch a YouTube video as I wasn't familiar with Gavin's mod.
Hi Baditude, Sorry I don't have an Ohm reader. Idon't even know what an Ohm reader looks like. I have 2 Panasonic CGR18650CH batteries. If the coils is the wire around the wick, It's two coils wrapped around the wick five times. I'm not sure if that info helps. Thanks
It is getting scarey! It's the people who have never used an ecig before and are going straight to the advanced and potentially dangerous mechanical mods with a super sub-ohm rebuildable on top. They don't appear to realize/understand that using these requires some personal research on their part. These are more complex than using an eGo or a Vamo.
I appreciate the help guys but honestly it is starting to frighten me. Is what I'm using dangerous for a newbie?
Just curious, what made you to purchase your current setup? What had you used before it? Before purchasing your current setup, did anyone educate you at all about it? Who did you buy it from?
The batteries that you have are safe batteries, depending completely upon what the ohm measurement is of your coil. Those batteries have a 10 amp continuous discharge rating, which will be safe to use down to 0.6 ohms coil
Owning and knowing how to use an ohm reader or a digital multimeter is a must if you are going to be using a rebuildable atomizer. There's no excuse to not have one.
ohm reader
digital multimeterOne of the above tools is needed to measure the resistance/ohm of the coil. This measurement determines how many amps the battery must have to power the coil. If the battery does not have enough amps, the battery will over heat and go into thermal runaway and vent hot gas. If your mod does not have adequate venting, the mod could explode like a pipe bomb.

When I first started, I followed your lead and have saved myself a lot of time learning the hard way. I avoided many of the pit falls of using a cartomizer, properly setting up my Provari, best selecting of resistance for simple atties, etc. All that prepared me for where I am now . . . Thank you.
Today though, Bad, vaping is moving ahead at such a rapid pace. There doesn't seem to be much emphasis on safety and understanding prior to jumping in.
I've tried vaping once before with one of those starter kits and it didn't even come close to making me switch from cigarettes. My friend turned me on to it again and I lasted a whole night drinking beer without cigarettes and for me it's impossible to drink without smoking so the next day I had one built just like his mod and that's what kept me of the cigarettes. Before the built, I did in fact try a starter kit in the same vape store and I didn't like it so we went on ahead and built the mod.
YES, it is dangerous if:
1. You don't have the proper tools for measuring the ohm of your coil
2. You are using batteries that are not rated high enough in amps for your coil or are using batteries that are not safe chemistry
3. You don't understand ohms/watts/volt/amps and how these relate to vaping using a mechanical mod
Until you understand all of this you should put your mechanical mod in a drawer until you have all the proper tools, know how to use them AND have read/understand all the links Baditude has posted.
Welcome, Gavin.
While blowing massive clouds can be wicked cool, please take a bit of time to become familiar with your equipment. I looked up your mod and your atomizer - they're both quite cool.
With regard to your mod, you'll want to fully understand how it functions and its limitations.
Lemme do some basic math with you regarding Ohm's (and Watt's) Law
Ohm's Law - V (voltage) = I (current) * R (resistance) So, if you have a 2 ohm (measure of resistance) coil and you're firing at 4 Volts, flipping the equation such that I = V/R you'll be drawing 4V/2ohms = 2 Amps of current.
Watt's Law - W (Watts) = V^2/R. In the example above, 4^2/2 = 8.0 Watts. That's a pretty safe operating zone.
If you change Ohms and/or Volts, the current changes in proportion. Things that you *MUST* watch out for include the concept of "regulation" (i.e. is the mod capable of "limiting" you within proper and *SAFE* operating parameters.) If the mod is *NOT* regulated, you must self-regulate (i.e. DO NOT PUSH THE DEVICE BEYOND SAFE OPERATING PARAMETERS.)
Let's change a couple of parameters using the math above and see what happens.....
Drop the resistance to 1.0 ohms, and leave Volts alone (4.0)
Current (Amps) draw now becomes 4/1 = 4 Amps of current. For some devices, this is no longer appropriate because the batteries either cannot or are limited by some sort of regulation that doesn't allow this much current draw from the device.
Watts in this example now get calculated at 16.0 (4^2/1 = 16)
Let's go one more time. Ohms are now 0.5, volts are still at 4
Current (Amps) = 4/0.5 = 8 Amps current. You're starting to push a lot through, and even MORE batteries (regulated devices and unregulated devices) aren't designed to tolerate this amount of current draw.
Watts = 4^2/0.5 = 32 Watts Few regulated devices can tolerate this level of operation (however, they *ARE* out there.) Unregulated devices *MIGHT* be o.k., but now you have to look at the batteries you're using to drive this bus. I'm not an expert on batteries, but if you read up and do some homework, you can find batteries that allow for higher-level current draw. If a battery is rated for 10A, I personally wouldn't try to push much past 5A - *I* want a margin of safety.
Be "respectful" of your equipment - make sure *YOU* know what you're running, and how it's supposed to work. As others have mentioned, get the proper equipment to *KNOW* what you have. Get an ohmmeter to read your coil resistance. Get a multimeter to check your batteries. Batteries will last longer and operate more safely as long as you use them within their *SAFE* operating parameters (which for most I believe is between 3.2-4.2V) DO NOT try to fire a battery when it's charge is less than 3.2 or 3.3 volts.
Once you COMPLETELY understand what you're running and how things work, if you wanna fill a room with a cloud - go for it Start out MODERATELY - it looks like your ATB can run upwards of 30W, but put yourself into a position to start with about 10W.
Be safe
