I have had my mvpv2 for about a week I am soo glad I got it..I am just a few weeks into vaping and this MVP is great. It was a Impulse buy at my local b&m..they only had gun metal blue..I have been looking for a buffalo bills skin for it, but had no luck. Does anyone have suggestions where I can a wide variety of skins??
Yes to some of the above post. The MVP will put out everything it can until the battery finally goes dead. Please don't let this happen. Most of these types of devices like to be charged before they are empty. When mine goes to a yellow light I start charging it.
6 watts and up=5.12v
It doesn't flucuate at all.
Then I don't understand how the system is working at all. 6 watts on a 2.3 ohm coil should not equate to 5.12 volts according to ohms law. It should only be shooting 3.7 volts.
Watts = Voltage * Amps. So if watts are set to 6 watts and the voltage measured is 5.12 volts, then you would be tempted to say, well that's easy, the e-cig simply regulates current. But it's not that easy.
Amps = Voltage / Resistance. Oh oh... Big problem. My 2.3 ohm coil is not adjustable, so the only way I can adjust amperage is to vary the voltage, but in the equation above, we said that voltage is a constant 5.12 volts.
So we've broken Ohms law. We simply can't have a set wattage and a set resistance with a set voltage. Something has to give.
Perhaps someone with more background on electronics can explain to me the magic.
There is no feasible way that an MVP would be outputting 5.12 volts across an entire wattage adjustment range.
Any electrical engineers want to school me?

Yes. I know it boggles the mind a bit, but remember this is more than a battery. It is a battery with a voltage regulation circuit.
The most common way this is done is using a boost/buck circuit which allows the output voltage to be either more or less than the actual voltage output of the cell.
If you google boost and buck circuits, you will get enough math to make your mind boggle, but suffice it to say that yes, it is possible that the unit will continue to output your selected voltage even if the "cell voltage" is below your setting.
I should update this. I agree, I don't want to invite trouble by picking a sore spot with the mvp connector either. But The "BB" was just an illustration of a small metal ball that fit the inside of the O-ring almost perfectly. An acutal BB is a little too big and fills up the cavity too much...
Wow, I think Santa must have had a lot of little black boxes in his big red bag

For those concerned about speaking on the connection issue, please don't hold back. We all know it is there and people are using several fixes and work-arounds. Hopefully, the more talk the, more likelihood of Innokin doing something about it. We did get one report of a newer v2 allowing a kanger T2 to work properly so maybe they have made some changes, but it was only one report. Would like to hear back from that person to if things are still working out.

I thought that there must be variable resister that can supply additional resistance other than the ohm from a carto or a tank.
I suppose it's possible....However it doesn't make sense.
First of all the variable resistor would have to be an extremely low ohm resistor and would need to be variable in extremely low values.
Two, you already have the buck/boost circuitry built in to adjust voltage with the variable voltage mode. It does not make sense to add "additional" circuitry just so you can maintain constant voltage. It makes a lot more sense financially to have a simple calculating circuit that compares set wattage to indicated resistance and then automatically adjust the voltage using the same buck/boost circuitry you are using to adjust voltage in VV mode.
I don't have a inline voltage meter, so I simply am going on theory only.

I can't say how the MVP attains it's set wattage, but I do know that my Darwin will vary both the voltage, and the amperage, to get the desired wattage. I can only assume that the MVP would do the same. Exactly how this is done, I have no idea. Electrical engineering isn't my thing... although I can explain the conduction pathways of the human heart if you like...
Does anyone know of any way to add some bling to my MVP? Cases, wraps, DIY glue on crystals? I'm all girl and I like my shiny things, lol!
Just a quicky. When I take my MVP off of an overnight charge the battery reads 4.2v. I take about two puffs and it is at 4.1v. It stays there for a while, and for ages at 4.0v before it starts to drop. Is mine unusual in dropping so quickly from 4.2?
Apart from that this thing hasn't been out of my hand since I got it (well, ok, not in the bathroom).

It's exact reason why I prefer protanks (mine is regular PT2). I've been using them without issues. The ones(I 16's) that came with MVP are sitting in my drawer for backups. Even when I need to use those I16's or I30, I'd shorten the wicks.. just too long for my taste. I am not saying that I am right, but somehow I can't stand long wicks..

Glad to know that someone in med biz is a fellow vaporer. I started on vaping due to my heart problem thinking that it'd be much better than smoking.I can't say how the MVP attains it's set wattage, but I do know that my Darwin will vary both the voltage, and the amperage, to get the desired wattage.

I wish someone can enlighten us with this mystery.
My other vv mods do the same thing. I think it's the nature of batteries (even car battery). They show around 4.1 - 4.2 at full charge and then drops to the stable voltage.Just a quicky.
