Very Nice!

I'm new to building coils and I bought an IGO W3 sold on the fact that it was great. Adviser failed to mention how tough it is the build a 2 let alone a 4 coil build. Tried 1 coil and it was OK but note to self...don't use 12mg nic juice...Knocked me on the floor. And I have to admit I was expecting tons of vapor. Does the MVP work well with these rebuildables? If you build a 1 ohm coil isn't that like 25 watts @ 5.0V? I was thinking that would put out some great vapor.

I need a tudor! LOL

Quads are a pain on most even a 5 post setup. You won't be able to build anything with quad coils that will work on an MVP well. Two should not be a problem hardest part is two wires through center and clipping the legs against the post.

Vapor is also a function of air flow so depending on your build you may need to open that W3 up by drilling air holes. I think I drilled my W3 out to 1/16. Start smaller and work up cuz you can't un drill a hole.

The MVP limit is 11w regardless of voltage. Yes 5v @ 1Ω is 25 watts. I use a mech mostly for dripping so max is 4.2v on at would be 17w. That is why I build at 0.5 ohms.

That being said you should be able to build two 2Ω coils for a total 1Ω build and run it at 11w on the MVP and get an enjoyable vape. It should put out more vapor than any clearo you can get for the MVP.

Blogging this for future reference for my A6 and RSST and future toppers.

Be it volts or watts you are just measuring power at different points.

Read up on Ohms law and check out
Ohmslawcalculator.com to see how they relate to each other when you start playing with numbers.

The theory behind wattage mode is that you can set for an atty with ohms set at X and should you switch attys ohms at Y they will perform the same because the MVP (or whatever VW mod) will adjust power (voltage specifically) to get the same watts regardless of what Ohms your atty is at.

The theory and application here do not always match. Generally speaking for most people using clearomizers on MVP the theory will more or less hold.

The main reason for this is clearos using stock heads do not have a very large range of impedance (ohms) ratings on the available stock replacement coil heads AND the fact that they all more or less use fairly small gauge resistance wire.

So for example using wattage set to 11w with a resistance set at 2.4ohms you need approx 5.1 volts to achieve this. Now if we switch to an atty 1.8ohms you only need approx 4.5 volts to hit 11w. All other factors being equal in a 2.4ohm atty and another set to 1.8ohm on a device set to 11w then YES they should perform very similarly, because the reality is we are only dealing with just a .6 voltage difference. which besides crossing the tipping (ie burning) point of your atty or juice IS NOT a huge difference in power or performance in reality.

Lets take a more extreme example and say we have a device that can hit 20w of regulation. With an atty set to .7ohms you only need to apply approx 3.7v to reach 20w. Now as with the previous example lets presume all factors being equal but we use a 1.3ohm atty (again, difference of .6 ohms like the previous 11w example) then in order to hit 20w we now need approx 5.1 volts. Now the discrepancy in applied voltage is 1.4v, which is going to have a much more noticeable effect on the quality of your vape. In all likelihood in this example the 1.3ohm atty at 20w will be a lot hotter than the .7ohm. Again presuming all things being equal save for the resistance of the attys this would largely be because of the way a certain wire gauge reacts to voltage but is really a different topic unto itself.

TLDR or conclusion

Variable wattage can offer an easy set it and forget it mode for devices that do not have a wide range of applied voltage NOR wide range of different resistances (in particular sub ohm attys) that can be fired such as a MVP 2.0 with stock clearomizers.

HOWEVER the variable wattage set it and forget it theory does not hold up with devices that offer a wider power range and can fire a wider range of attys, such as many of the 20 to 200w mods and all the different rebuildable attys out there.
So all in all with the more advanced powerful devices they may as well be variable voltage only because if you are using a wide variety of attys you will need to adjust the power.

(For some strange reason I am adding more to this because I decided it is not long enough)

what this really boils down to is the character and quality of your vape cant be simplified and attributed to just a single dimensional understanding of power. There are tons of variables and exceptions to consider, with personal preference being the primary factor, so do not be afraid to play with the voltage AND the wattage mode to find what works best for YOU.

Vape on brothers and sisters
