Both the Provari and the Darwin are the current favorites by many who like variable voltage/wattage. The Provari will adjust to your desired voltage and the Darwin will dial in the wattage (heat) you prefer. Both are excellent devices, but it really depends on what you are looking for in a vape. Best thing to do is to go and watch some video reviews on both, and come back here and read their forums. You really can't go wrong with either.
Thanks Retriever! I don't understand the voltage thing either. How do you know the volt you are vaping? Which is better
I agree that these two are top of the line. I prefer the Darwin for many reasons but probably the biggest reason is the consistency. No other PV is as consistent over the 21+ hours it holds a charge than the Darwin, IMO. The last inhale is the same and as good as the first one off the charger. Here is a new review:

Probably the only argument against the Darwin is that you can't really buy it - they've been out of stock since I started vaping... Anyway, maybe on the classifieds?
Variable voltage means exactly what it says: you can change the voltage your battery unit puts out. The voltage affects the way your atomizer/cartomizer works - higher voltage means higher power output of the coil and results in more vapor, warmer vapor, and more throat hit, more and even different flavor. The other important variable is the resistance of your atomizer/cartomizer. Power is easily calculated: Power = Volts x Volts / Resistance.
There are many VV options out there. Some are tweaky, more difficult to use as they don't display the voltage at all and you need some form of tool - a screwdriver for instance - to adjust the voltage, and you need some form of meter to figure out the volts. Others have a easy to use wheel like the Buzz and Infinity Pro. These two also do not display the voltage, but you can really just adjust it based on how the vape feels. Yet others, like the ProVari and the cheaper Lavatube have built in meter showing you the voltage. The Darwin also takes care of Ohm's law for you and you get to directly adjust the power - it also changes the voltage as the resistance of your carto/atty changes to keep constant power, something no other VV device does. The resistance tends to change with temperature - as in when you're chain vaping and the thing gets hotter - or with longer use.
I would first figure out if I like / need / want variable voltage. What are you using right now? Depending on that, you may want to try lower resistance cartos, or use a VV box mod from MadVapes, or even a 5 V passthrough just to get the feel of it. Or jump in and buy a more expensive device, like the ProVari.
As for the ProVari - what's special about it is that it's a beautiful device, works flawlessly and gives me a lot of satisfaction. I posted how I feel about it here: The ProVari is here to end all quests - Blogs - E-Cigarette Forum

Wattage basically refers to the warmth of the vape. Voltage is power supplied to the atty/carto. You can get close by using a low resistance cartomizer on a 3.7 volt device without having to go to variable voltage/wattage. Something in the 1.7 ohm range like a resurrector is what I find to be satisfactory for me. Might work for you too.

Regarding suggestions that you try lower resistance cartomizers, that is a good idea provided your batteries can handle them. If you are using small, cigarette-sized batteries you need to avoid LR cartos or attys & stick with standard resistance stuff. Low resistance requires a higher current capacity (generally above 450mAh) to avoid damaging the battery.
Best of luck & Happy Vaping!

I am still happy with my Ego. That didn't stop me from acquiring a Lavatube-type to play with VV mods.
My egos fit comfortably in my pocket and are easier to go in public with, though, and people look at you strangely (at first) when you're carrying a larger PV. I suspect that I'll be using both interchangeably... although at home and at my desk at work, oh yeah, the lavatube's coming out. I am happy with my lavatube , why should i need a provari. The PV looks real nice thats for sure, but if i would spend much money for a vaping device, it would be for the darwin.
I've been wondering the same thing lately....Lavatube or ProVari....have ego now but NEED VV. But the question is do I spend the money on a LT now then end up buying the ProVari later? Or suck it up now and shell out the dough for the Provari up front??? Delimas.....
Sorry, but this might be confusing for people. Wattage is Power, and Voltage is Voltage (not power).
Wattage isn't the warmth of the vape. The warmth of the vape is a result of the wattage (The amount of power the circuit is producing which is expressed in Watts)
Power = Volts x (Volts/Resistance)
Lowering the resistance of the coil will produce higher wattage (resulting in a warmer vape) at the same voltage.
Increasing the Voltage and keeping the resistance the same will also increase the wattage.
Example:
3.7Volts with 2.0 Ohm carto.
3.7/2 = 1.85
1.85 x 3.7 = 6.8 Watts
3.7Volts with 3.0 Ohm carto
3.7/3 = 1.233
1.233 x 3.7 = 4.56 Watts
5 Volts with 2.0 Ohm carto
5/2 = 2.5
2.5 x 5 = 12.5 Watts
5 Volts with 3.0 Ohm carto
5/3 = 1.667
1.667 x 5 = 8.335 Watts
I prefer the darwin's system of dialing in the desired wattage as it addresses the end result of the equation directly regardless of the attachments you're using on your device and does away with the guesswork and the endless series of clicks.

How does it know that I switched juices and prefer the other juice at a different wattage??
