Very new
I am very very new to vaping and I've been doing my research on safety (ohms,watts,volts,amps). After watching about 5 videos, I still don't understand a damn thing. So I am just asking as an example, if I vaped at 200w with a .5 ohm coil using a Lg HG2 battery, would the whole thing blow up? If not, is there anything wrong with that setup or am I completely safe? This has been bugging me, and I can't seem to figure it out myself. Please Help! Thanks.

RE: Very new
Most pre built coils have their limits rated by the manufacturer.
It's not so cut and dry.
Also, you cannot (as far as I know) reach 200W with a single LG HG2 18650.

To answer your question; if you were using a quality mod with protections; quality batteries, and an atomizer with a .5 ohm Coil, It's likely that it wouldn't fire due to the self limiting chips and such.

I'm not an expert, and I don't suggest you just run out and vape a .5 ohm coil at 200W.

RE: Very new
Welcome to TVF Noble.

One of the first bits of good info I got when I visited my first vape shop was to always start low and work my way up...you won't damage your gear or risk anything by ramping up versus the alternate..... as already noted, coils state the recommended range and there is a reason why there are regulated and mechanical mods...it is always recommended that beginners start with a regulated mod as it takes the majority of the risk away... that doesn't mean care and common sense shouldn't be practiced as it is an electronic device...run a few "how to safe vape" youtube searches and you'll find a great deal of material, most will centre on the core of safety being the batteries...

Good luck in your quest.

RE: Very new
Welcome to the forum! 

We've got a FAQ Section where you might find some info, especially in the thread called "What the Heck is Ohm's Law?" where I did a lot of math. Basically, you need to make sure you don't exceed the amp limit of your battery. A single 18650 should never be used above about 60W, ever. I know, there are single cell mods that go higher, but even the best cells can't go higher than that without risk of venting. The FAQ has more info, I'm kind of in a hurry right now so I'll come back and answer any more questions later if no one else comes around to you first Tongue

RE: Very new
Here are some links to articles Michael mentioned.

FAQ Section - The articles in this section are not only informative, but will help you feel confident and safe when you vape. It's a lot to learn, but that's why vaping is fun.
What the heck is Ohm's Law - I use the article below when determining the right range to vape at.
Where Should I Set the VV/VW on My Mod - I just used this section to make sure it was OK to use 65W with .5 coil. Because the volts showing on iPV 6x is showing 5.79 it should be OK. If not, my coil will burn out faster than usual. Personally, I think if you could actually get your module to go to 200W, you'd burn your lips and mouth.

RE: Very new
Just to elaborate a bit on this, since I have time to make a more detailed answer than before:

I did a bit of math concerning your question. If you're using a 0.5 ohm coil at 200W, you'd be looking at 10V and 20A. The LG HG2 can handle around 15-20A, so you'd be right on the borderline of what's safe or not. But keep in mind, that's in a perfect circuit with no loss anywhere. In real life, there's no such thing as a perfectly efficient electrical system, so you'd lose a bit of power here or there and realistically you'd be using more like 25A. Also, most coils are designed to be used in a range around 3.5V to 4.5V, so you'd be using more than double the power its intended for. At best, you'd get very bad dry hits and burn up the cotton in your coils. At worst, it could put too much strain on the battery and cause it to vent or even explode. 

Realistically, a 0.5 ohm coil should be used at around 30-40W for the best vaping experience. 

Now all of this is based on just the numbers. Some coils are made to handle higher power. For example, I know from my own experience that the 0.5 ohm coils for an Arctic tank are good at around 50-60W. If I made my own 28/34 fused clapton coils with a 3.5mm inner diameter at 0.5 ohms, I'd be able to run it at 100W or more. It depends on a lot of other factors, like the size of the coil, the coil's inner diameter and wicking, etc to determine what a coil can do. I'm just using the math to help for now since that's all I have to go on.

RE: Very new
Welcome, you are in good hands here, I am new to vaping and it might help to read my thread as there is great info in it from the members here.

http://www.thevapingforum.com/Thread-Rea...after-ecig


My suggestion being new to vaping and just getting my first mod is KISS = keep it simple stupid

There is always room to grow and move up the vape chain so don't jump in to deep to start. There are plenty of great entry level devices out there to get your feet wet.
