I'm looking at mods now ... not sure if I want to go in this direction or not. I'm pretty happy with my eGo and the various accessories I've gotten with it.

But I saw the Little Sister and I fell in love with the way it looks.

Could someone explain variable voltage - what it means in terms of e-cig use, the pros and cons (if there are any cons) etc. I've been surfing through pages getting bits of info, but I figured I might as well just ask outright to avoid getting confused.

Thanks for your help.

Variable voltage allows you to dial in the sweet spot in terms of flavor and heat.

Ohm's Law: (Voltage x Voltage) / Resistance (ohms) = Wattage

The ego: (3.4v x 3.4 v) / 2.2ohm = 5.25 watts
The ego with an 1.5ohm LR atty : (3.4 x 3.4) / 1.5ohm = 7.7 watts

A 3.7v mod: (3.7v x 3.7v) / 2.2ohm = 6.22 watts
A 3.7v mod with a 1.5 ohn LR atty: (3.7v x 3.7v) / 1.5ohm = 9.13 watts

The flavors and heat intensity can be changed by using different attys, or changing the voltage. A variable voltage device allows you to change the wattage, without changing attys.

For most vapers, the "sweet spot" from a power perspective is between 4.5 volts and 5 volts. It just provides a better throat hit and more consistency. But every atty/carto has a different resistence and thus vapes better or worse in relation to the power provided by the battery. Even different eliquids taste different from one power level to another. So with variable volt, you have more flexibility to adust the power to "your taste/inhaled feel preference". Not all variable volt PV's are created equal, however.

One example I will provide. Since the 510 is so frequently used, many new vapers don't know what the difference would be with a different atty. I personally prefer the 801/BE112 atty over the 510 because it is larger and vapes a little cooler. But I don't like it at 3.7 volts - just too cool. But at 4.8 to 5.0 volts, the 801, IMO, out performs the 510. It allows you to taste the eliquid better, IMO, but still has a very good throat hit and warmth at the higher voltage level. There have been a number of "converts" to the 801 from the 510 once they got a variable volt PV.

Thank you very much for the replies. It makes much more sense now.

And yes I have a bridgeless 1.5ohm LR 510 Atomizer. I can definitely taste the difference between that and a reg 510 atty.

One question .. how long does the 10440 battery last - on average?

Also wv2win:

Very interesting. What variable volt PV out there is the best right now - or, the best vv pv for the price?

Of course the answer to your question is subjective to a point, but AG's three example are the top three, IMO, with the Darwin and ProVari being a little higher up the ladder than the Infinity simply because they have more features. I just bought the Darwin and thus can tell you why I think it is the best, performance wise but that the other two are also right up there in performance.

First, the Darwin is the only VV PV that actually senses the resistence of the atty/carto as you vape and automatically adusts the power to the atty to maintain your initial setting, so the consistency is unequaled IMO. As the user, you don't have to do anything, other than vape.

Second, the battery is built in. I am a very heavy, constant vaper as I work from home. I was able to get 21 hours on a full charge. Others in the Darwin thread have reported getting up to 35 hours on a charge. So for me, I can charge it every night and never have to worry about bringing extra batteries. And since it has a regulated boost circuit, the last vape just before the battery dies is as good as the first one. Plus it doubles as a pass-through, so you can charge and vape if you need to.

Third, the build quality is top of the line. It feels so solid that many of us who vaped on it first at the Atlanta Vape Fest joked that we could use it for "personal protection" if we needed too.

Fourth, it has the best warranty that I am aware of. A complete 2 year warranty on the PV and 1 year on the battery. If you need to replace the battery after the first year, you can send it back to Evolv and they will charge $25 to put a new battery in it and you then get another 1 year warranty.

Some people do not like the looks and of course that is subjective. I can say it fits nicely in your hand. My only issue with it so far is that the wheel to adjust the wattage (power) is a little sensitive and you have to move it just a bit to change the wattage one tenth. I personally like that when you close the arm, the unit shuts off so you never have to worry about it being on in your pocket.

The "Best" is rather subjective.
The ProVari, Darwin, & Infinity are all great devices, but not feeders. The Monkeyboxx & Ali'i are the only two VV feeders currently available, but others are sure to follow. They can all use different attys with an adapter.

Ok. I just sent you a PM about juice boxes. And now this ... yes, it's starting to come together for me now. Thanks!

Very nice. Thank you so much. Between the two of you I'm getting somewhere! Thanks for taking the time to write that up. I think, by the time I have the money to purchase what I want - I might actually know what I want. lol

Glad I could help. I can tell you are one of the new members who believes in doing reseach and learning as much as you can. I think that is admirable and a good trait to have.

wv2win is the Darwin poster boy LOL ;-)

But he is 100% dead on with everything he said. I'll simply add that even with the atty's & carto's, the resistance can vary. I have a box of 510 cartos. The last 3, the Darwin showed me one was at 2.8, one was at 3.0, and one was at 3.1. Those variances are within specs I'm sure. The good thing about the Darwin though is that once I set my watts (7.0 is my sweet spot), those variations in the cartos are irrelevant- the Darwin automatically adjusts the voltage to keep them all exactly the same.

This is a great thread. I just discovered what a higher voltage can do and will be saving for VV which will be my first mod.

Does anyone have any input on the other ones mentioned by Almightygod?

"The "Best" is rather subjective.

These are obviously top of the line, but what about some other options in other price ranges?
