Greetings all!

Still smoke free, still loving it! I just got my VTR in the mail today and I have the Power Chart handy for a reference.

(Here's the link to save folks time:) http://25.media.tumblr.com/tumblr_m9dkanCt0I1qc8949o2_1280.png

The VTR says my atty (IClear30) is 2.1. I set the voltage to 3.7 and the watts to 6.0. Just want to make sure I'm reading the chart correctly. Seems like I could go up a bit in wattage if I wanted but I'm happy with the vape I'm getting at the moment. Knowing me, I'll want to tinker in the future. I know Ohm's law, well at least the formula, and can do the math, but what I don't have a feel for, which the chart helpfully depicts, is when I'm out of a good boundary zone. Should I just follow the chart?

What would be my experience if I went to an atty with greater resistance? Would I then get to be able to get a thicker (if that's the right word) vape because I could up my voltage and or wattage?

I was under the impression that with a vv/vw you would set one or the other and therefore thought if I changed the watts the voltage would change automatically. But that's not the case, each can be set independent of the other. So the change in resistance of the atty is what would allow me to stay in the "green zone" and vary my volts/watts. Is this the correct way to think?

Edit: if I changed the ohms on the coil and changed the watts wouldn't the voltage have to change to keep within Ohm's law?

Somewhere in here I know changing these settings and/or atty can cause increase or decrease in battery and coil life, and amount of liquid used. I guess this is another confusing part for me.

Any help on any of the above would be greatly appreciated!

Kind Regards,
Blackie

on the VTR you can only use VV or VW, not both at the same time.

Well with VW you set the power to whatever you want, and then it reads the Ohms and sets wattage accordingly and gives you a more constant voltage.

someone correct me if i am wrong


EDIT: if you have it at 8.5w with a 1.8ohm coil it will push out a certain voltage. but if you have it set to 8.8w with a 2.2ohms coil it will push out a different voltage. you can use ohms law to figure out what it will be pushing for both. there is also a calculator if you want to find it online

That would be my guess. I'm finding I'm liking it at a higher wattage (8.5). I just don't want to burn my coil out prematurely as only one came with it. Have some more on order..... If I do though I have other options so it's not the end of the world. Got a IClear 30 and Kanger II and III. Between those and the 30s I'm trying to figure out what I like best. Unless someone chimes in and says "DO NOT" run at 8.5 watts I think I'll try that for a while. I am liking the VTR even though it's big. But big in a good way. I also picked up an SVD and that's just too long. I may go to a 18350 battery in it. Both are just for house use, I've got other gear for when I go out. Which isn't that often....

I believe you are correct. I played around with my new VTR as soon as my first Panasonic NCR18650PF 2900mAh High Drain 10A IMR Li-on battery was charged, and it became clear that the two modes (VV or VW) are independent of each other, so you don't have to set both. Which makes sense, of course, as wattage - as I understand it - is dependent on both voltage and on the resistance of the coil.

I run my iClear 30s up to 10 watts on my VTR with no issues. So I would say you should be good to go @ 8.5. And the guys above are right; you use VW OR VV, not both together. VW is nice because it adjusts the voltage for you based on what your atty resistance is, but sometimes it's nice to adjust your voltage yourself, so I find myself switching back & forth between the two....

Cool. Thanks all for the replies, I think I've got a handle on it now. Sure is nice having the control! :)

Agreed! I am loving my new VTR....The thing is built like a freakin' tank....I just ordered an MVP for my wife (who just quit smoking/started vaping) so it'll be interesting to compare the two!!
