Thanks Everyone!

So I want a lower ohm coil, not a higher ohm!?! I was thinking I needed higher ohms to avoid the burning. Arghhh.

edyle: The problem with the tanks I've seen is I can't just swap out a head if I'm leaving the house or take extra coils with me. I haven't shopped in quite a while so maybe there is something new out there.

yeah like I said:
but nowadays instead of rebuilding protank coils you can get the subtank mini and use the rebuildable heads

you can swap heads with the subtank mini just as you swap heads with your protank.
the difference is the subtank different heads, including heads that are designed for rebuilding.

Volts squared / Resistance (in ohms) = Watts, so
3.4 squared/2.4 = 4.82 watts is what I am used to vaping


Can someone tell me how to do a calculation, when I am stuck with a minimum of 7 watts and the mod automatically figures the volts - what ohm coil do I want?

:(

No matter what resistance you use, you will still get 7 watts with your mod. The only solution is to use a different mod.
Eleaf 30 Watt for example can go to 5 Watts and no lower. I think that is the minimum among all the mods.

I have a Vamo left but it's on it's last leg - been using them for a few years. Needed a new one and after hours of researching because of the change to watts and shopping locally (and posting on ecf) I ordered the Kamry V2. Apparently vaping on low ohm coils is the thing now. I'm trying to find out what I can change (coils) to still use the Kamry mod - I like except for it doesn't go down low enough. I don't have a lot of money to spend so I make my own eliquid and coils. I can't spend $50 on one tank.

(I hate starting new threads unless I have to since the forum is cluttered enough. I do have another thread when I was shopping for the new mod (Need a new mod and have been out of the loop for over a year? | E-Cigarette Forum I had already placed my order when someone told me about "step down".

The only things I can do are change my coils or buy another Vamo.

Have you tried a coil at 2.8-3.0 ohms? You may have to go larger diameters on your coil.
Steam Engine has a feature that compares heat generated by different gauges. I think the thinner wires produce more heat.

From what I understand, I need to make lower ohm (resistance) coils for this mod. If I increase the ohms, the mod automatically increases the volts because it can't put out less than 7 watts. If I decrease the ohms (using fewer wraps or thicker - lower gauge wire) the the Kamry lowers the volts as long as it doesn't come out to less than 7 watts. With a lower ohm coil "I can turn it down" and still stay above the 7 watt minimum. :?: I don't really understand it.

Volts squared / Resistance (in ohms) = Watts (Cannot be lower than 7 watts)

Thinner wire will yield higher heat, but that's just half the picture though, as thicker wire will have more metal which will be harder to cool with airflow and juice/wick, so in the end, thicker wire will normally be the hotter one...

About ohms, then what happens if you make a 3 ohm coil? Even at 4.2 volts, its still only 5.88w. OK, if it indeed isn't giving out under 7w under any conditions, then it will set the voltage even higher, but normally, then you always build higher, not lower, to work around a mod that cannot step down... It's strange that it helps you to build lower, though ?

That's what I thought at first. But if I build a .5 ohm coil, I am able to lower the volts because I stay above 7 watts. The higher ohm I build the coil the mod keeps upping the volts to meet the 7 watt minimum.

I still don't understand how this all translates into "burning my juice". I think, I have more wiggle room to play with on a lower ohm coil - I can turn the heat down because I'm not going below 7 watt? I don't know if it is, in fact, lowering the heat on my coil. It's still a bit too much on a 1 ohm coil.

Why'd they have to go and change everything to watts :nah:. I had enough trouble a few years ago with volts and ohms. I'm not a hobbiest and vape tobacco flavor only. I use it to stay off cigs. I'm missing the simplicity of pulling out a cigarette and lighting it.

Well, if building a 0.5 ohm coil, then you can turn the volts down, but that dosen't help, when you're still locked at 7 watts, as you say. Volts alone isn't interessting, but only the volt/resistance combo is the usefull thing, and it's there where watts is nice as it takes those calculations out of it i.e. 7 watts is 7 watts no matter if you change builds from 0.5 to 1.5 to 2.5 ohms, but your issue here is the locked 7 watts unfortuently... Build a high ohm coil, with thinner wire around a bigger bit 2.5mm to 3mm and space your wraps as in don't build a contact coil(micro/macro coil), as even though you cannot turn it down, then it's set at 7 watts at the lowest setting. The higher ohms will be less hot and spaced wraps and also a bigger id cools the coil even further with more juice/wick. You shouldnt get burnt anything with 7 watts though, so check your wicking techniqes, as 7 watts is comparabel to a starter ego kit or thereabouts...

I have an ego that I used and vaped around the same volts as my Vamo. I have no idea what watts the Vamo V5 or ego have. I'm so confused. Wicking could be the issue and I'll build some more coils tonight, but leaking is touchy in the heads. So frustrating to work so hard to get things just right and then I have to change.
