Any VV device will perform the same with a 2 ohm single coil or 2ohm dual coil. The circuit sees 2ohm irrespective of how many coils there are. What will differ is the heat per coil only.

The ProVari will top out at about 4.9v before it fires off the E2 error with a 1.5 ohm dual coil. That's still pretty good, especially because it really is 4.9v

Phil does some amazing videos, doesn't he?

Just visited Busardo's Provari Review again and the charts show it to be a beautiful performer at each given setting. What I would be curious to see is what happens with the 1.5ohm DC carto that has pushed the unit to near max at 5v according to his chart. I would want to test the unit to it's very max, say 5.2v with a fully charged battery then test it again with a depleted battery to see if it would still perform at 5.2v.

That is what I did with the Lavatube, all of those readings were the very max the PV could produce with a full charge and a partially depleted battery.

BTW what did you think of Busardo's introduction for the Provari, I was truly impressed and I'm not even a Provari loyalist. :)

I have V2 equipped ProVari. The claim is true :)

>"This device also features regulated output; as the battery charge drops, the device will keep the voltage at the same levels, until there’s not enough charge left in the battery."

Finally did some testing on various vaporizers and was a little surprised at how much the output voltage dropped as the battery drained at any given setting. I posted the chart at http://www.e-cigarette-forum.com/forum/gotvapes/2… Post #259

After these tests I had a near uncontrollable urge (up to entering my CC #) to buy a V2 Provari to see if their claim of constant output voltage was true. :)

The higher resistance dual coils to work at 6v on this and the ProVari pretty well. I'm still on a quest for an elegant mod that can run the 1.5 ohms at 5+ v.

Sounds about right. with the 2.5 amp limit, 1.5 ohms @ 3.7 volts would be 2.46 amps. So really what users want, is a VV device with a higher current limit. You can prolly use some dual coil 2.5 ohms with this thing, and theoretically, it should get to 6.0 volts. Not sure, I dont own one.

>"I'm still on a quest for a full featured variable voltage e-cigarette than is smart, but dumb enough to light up dual coil hardware at high voltages."

That's what I'll be waiting for in this price range. I'm guessing the low amp switch has something to do with the circuitry to get higher voltage out of a single 3.7v battery. A dual bat 3.5amp should do it. :)
Nice review Steve.

Awesome!!! definitely getting one…only 69.99?! wow

Just got one. There is a voltage lock feature. Hold the + and – buttons. I only have a few attys and also an LR dual coil tank similar to the pic you posted above. I don't have a way to measure the voltage but it holds even at 4+ volts. Not sure if the LCD is just locked from changing the value or if the voltage is holding.
