Being an electronics junky and ocd hobbyist with an EE background and new to vaping I'll add what I've seen and learned so far.
VW is a compensation for not so good VV regulation. Tight constant regulation becomes more important as ohms drop on coils as it runs on the line of burnt taste if it is crossed.
Imo, tho more you get into vaping the more you learn what you like and begin pushing those devices to get the perfect vape.
I like to modify everything, but do my best to keep well below the burnt taste threshold. Meaning I'll mod a tank before pushing the V or W's up.
Vamo- I have one and like it alot.
SVD- I just got this and it is built better than the Vamo. The adjustments are harder to learn to.
I do swap batteries at 3.7v, not due to the device as much as the batteries have more amperage limitations at lower charges. I do notice power drops at this point with the Vamo and SVD.
I'm gonna mention this as I don't like the MVP until they make one with swappable battery packs, I don't trust others to pick out the best performing cells in anything. So I stick with swappable battery devices except for my on-the-go spinner/Evod setup.
Provari- I've never even held one. But quality wise I can tell its one of the best regulated devices.
Worth $200? Not to me.
$140? Yes it is.
I had many high end cells and chargers from my led flashlight hobby days, so initial costs are lower for me.
A Vamo or SVD with a cheap non imr cell would be torture to me.
A Provari with a cheap cell will act normally but just not last as long on the charge.
Most who use mechanicals wouldn't go near a cheap cell as the who device is useless without great power delivery. I'm referring to amperage output under load on a scope. Yeah I've done that stuff too!
So as I grow in my vaping experience I'm sure I'll always be looking for a better vape, having the best equipment makes finding it easier and have less hassles.
Will I buy a Provari? Possibly.
But I'll be looking at other options also as I know a time will come when I need that good regulation.
Very well said. And worded.
