Was going to, but shipping time :( Got another week on holiday from work, so was going to get it built before I go back as I can borrow a soldering iron and drill from the unit underneath mine :p

You most certianly will see a lot more vapour (And denser) sub ohm'ing.

Sure if you are just going mouth to lung it does not really matter. but straight to lungs you will see a massive differance sub ohming.

The extra heat makes sweet tasting flavours amazing too. So much so if I see a 1 instead of a 0 at the start of my ohm reader I rip it out and start again.

*edit* And also the extra throat hit you get when using 0mg nic juice makes you not even miss the nic.

yes if you have a massive air hole!!

I have a dual coil dripper @ .2 Ohm on an 18650 mech 1.8mm air holes, yes I can blow thick clouds all day long lunging it!
I dont like waving a big heavy mech so I now drip with a 18350 hybrid, 1.1 Ohm single coil, air hole adjustable upto 2.2mm, with it fully open there is no difference in the amount or quality of the vaper, although I do find the taste better.
While it is fun to blow big clouds I do vape like I use to smoke (little and often) so use a mesh genny and a nice tobacco steep. Occasionally I do fancy dripping some custard, but not at .2 Ohm just don't see the point:confused:
It just ain't necessary IMO;)

I would imagine in a few days it has already payed for itself anyway so can only be a good thing from your point of view :)

Yeah, had it two days now. In that time I would otherwise have done two 12.5g pouches of baccy, so six days worth and it's paid for itself! And as I know the girl in the shop, she threw in a free 30ml refill bottle too...

hi guys right for the last year i have been using just a standard ego batt with a pro tank 3 mini but today i decided to treat myself to a mvp with vv and vw lol

now i will be honest i thought you could adjust both but have been told you can just adjust one .

so which does which does one give more vapour and one more flavour ?

i really am pretty thick where electric maths come into it lol


for example if its on 4.2 and the watts are 8.0 can you change it to 4.5v and 9w or can you only change one lol

a simpleton explaination would be great cheers :)
 
Vapour and flavour will come from the atomiser not the battery box bud.

Not sure with the MVP but on my SVD you could change both, was vaping a 10.5 and 4.8 for some juice and then went 8.0 and 4.1 for others.

If you want good vapour and good flavour look into a rebuildable attomiser! Best thing I ever did!
 
P=V^2 / R

So

Power = (Voltage x Voltage) / Resistivity

So, in essence, whenever you change voltage OR power, assuming the resistance of the coil is the same, you change BOTH.

Example. You have a 1 ohm coil (for ease of calculation).

So, if you fire 4.2 volts over the coil you get (4.2 x 4.2) / 1 = 17.64 Watts.

Now, you can change the voltage to 4, so you get 16 watts.

Or, you could have fired a 1.5 ohm coil at 4.2 volts, giving you 11.76 watts.

Or, you could have changed the watts, say to 10 (on the 1 ohm coil). This would give:

10 = V^2 / 1
10 = V^2 (Multiply both sides by 1)
Root 10 = V
V = 3.16 volts

Had this been the 1.5 ohm coil, V^2 = 15, so V = 3.87 volts.

Basically, what it comes down to is a balanced equation. You have 3 variables, resistance, power and voltage. When you make adjustments, the resistance stays the same, as it is the same coil. So whatever adjustment you make, Power or Voltage, it affects the other variable such that the equation remains balanced.

This is a basic misunderstanding of the physics behind the device. When you change two variables, only the last change is viable. So vaping at 10.5 watts, then changing the voltage, means you are putting out whatever power is given as a result of the voltage across that coil. Yes, you can change either Volts or Watts, but it is the LAST change only that is relevant. It COMPLETELY negates any change to the other variable. When you swap from voltage to power, you are changing the power to give a certain voltage over the coil, and you are in Power mode, NOT voltage mode. And vice versa.

In this instance, assuming he changed wattage first, then voltage, as his statement reads, he actually would have been vaping at 4.8 volts, and 4.1 volts. The ACTUAL power (wattage) he was vaping at would entirely have depended on what resistance coil he was vaping at that voltage.

Similarly, if he had changed voltage first, then power, he would have been vaping at 10.5 watts, and 8 watts, with the voltage applied to the coil completely dependant on the resistance of that coil, at that wattage.

EDIT: It is also a dangerous game rebuilding your own coils when you haven't really grasped the basic Physical concept of what is ACTUALLY happening. You SHOULD be okay on mainstream VV / VW mods, as they wont fire a low resistance coil, but make sure you UNDERSTAND what you are doing if you decide to throw a build on a mech mod that doesn't have any protection circuitry.

dont worry i wont be doing any rebuilding for a while lol

i get what your saying just about but still cant understand if one over rides the other then why have both on there ?

been looking at a chart and for my coils which are kanger 2.0 ohm dual coils it suggest 8.5 w so it might be best i dont touch voltage and just set to 8.5

still cant fathom why both are on there then lol
 
Well, back in the day, voltage was what people varied. It wasn't really until someone thought about what was actually happening that devices changed to vary wattage.

The reason for changing power rather than voltage is that when you change your atty, the resistance will also change, more than likely. Your vape is mostly determined by the power produced, and so if you keep the power constant, the vape should remain reasonably constant. So when you change the resistance, the voltage automatically changes to keep the power the same.

So both are included. It is also possible that the 0.5 watt adjustment might not be accurate enough for you. Varying voltage, usually in 0.1 ohm increments, might just be the fine tuning you need.

Also, try different power levels. I find pre-made coils often ain't up to much above 11 watts, but I like vaping 10 watts and above now (never used to go above 6). But when you start building your own coils, you can get them to wick properly. My drippers fire at over 100 watts with no issues.
