Hi all!

Relatively new Darwin owner here...I've read so much of this thread I think my head is going to explode, but have never posted until now. You all really helped me make up my mind that the Darwin was the right choice and I don't regret it at all.

I do have some problems with mine, wobbly USB, weird goings on with the atty connector, but as many have said the guys at Evolv are great and got back to me right away. Hopefully I'll get my loaner unit by Tuesday ... but had to order a passthrough and epower as backups for now.

Otherwise, this thing is the bomb. Weird thing I can't get much past 5W without everything starting to taste burnt in anything but a 4.5ohm 801 that I have...in 2 days use that one went wonky down to 2.6ohm. Also, fluxomizers work great on it!

I find with LRs the battery lasts all day (about 5ml per day) with a little charge left when I plug it in at night. With SRs you'll easily get 2 days + on a charge. Honestly, if most of what I have on hand wasn't already LR I wouldn't bother with LR on this thing anymore. You can get the same vape from an SR as an LR on the Darwin no problem since you set the wattage you want and everything else auto-adjusts to maintain that, but with the added bonus of not draining the batt as fast

EDIT: I type too slow :p I keep finding myself repeating other people's posts . . . :facepalm:

This is something that's always confused me, why do LR atty's drain the battery faster? I admit that I don't know too much about electrical things (unless you want to know about the electrical conduction of the human heart). But I would think that if a coil had a lower resistance, that it would take less energy to heat it, and a higher resistance would take more. So I don't really understand how a higher resistance uses less power than a lower resistance to heat a coil to the same temperature.

While I'm at it, I'm confused by the whole dual coil magical math thing. How does 2+2=1?

Hi all, been gone and busy for a few days. Red Dog, LR uses more amps to get the same amount of watts. More amperage runs your battery down faster, assuming the same wattage. The 'big numbers' are the most important thing. Darwin adjusts voltage to match the resistance of your atty/carto, to try to put out the wattage dialed in. Even more cool, is the fact that it does it constantly, and will compensate as your atty/carto ages.

To do this with any other device, you would have to take it apart constantly, measure the resistance with a DMM. You would then need to consult a chart, and adjust your VV to keep it the same. Darwin is set it and forget it.

I'm not a strong math guy, but two resistors in parallel is like this: Final Resistance = (R1xR2) divided by (R1+R2). Resistors in series are easy, they just add together. Final Resistance = R1 + R2+R3+R4

For more than two resistors in parallel, it's a different thing yet.

On dual coils, I have used quite a few Smoktek ones. I have a 2.5 ohm dual on Darwin now. Full tilt, 12.7 watts (which I never vape that hot) it is drawing 2.2 amps, and it chooses 5.8 volts to get there.

Back in the day when I used mainly a VV device I used this calculator.....you can calculate watts, volts, ohm's with it.......plug in some numbers and see what changes.....EXAMPLE: 8.5 watts at 1.5 ohm = xxx amperage...and 8.5 watts at 3.0 ohm's = yyyy amperage...... the higher the amperage, the quicker the battery will deplete....

That didn't really answer my question. I know that that's how it is from reading this forum, but it doesn't really tell me why. I've never been one to simply accept that something is the way it is, I've always wanted to know why it is. Yes, I was a teacher's worst nightmare, I questioned everything. But I've always felt that it's better to fully understand why things are the way they are, because it often follows through into helping you understand other things.
For example, in medicine, a patient with a history of hypertension is taking atenolol (which is very common). Because of this, they will often not present as you would expect them to in some cases. Which can lead someone who doesn't understand how and why the medication works to misdiagnose a patient.

I guess in short, I'd like a much more detailed explanation of the whole interaction between voltage, amps, resistance, and watts. Any electrical engineers out there feel like giving me a lesson?

Amps draw is part of Ohms Law - it is a mathematical LAW of electrical current. By using a simple Ohms Law calculator: Ohm's and Joule's Law Calculator you enter any 2 of the four fields and click on calculate and the other 2 fields are calculated for you. 2 of the four variables dictate (mathematically) the other 2. The lower the resistance, the higher the Amps draw will be on any given volts or watts setting.

From there, read this post and see if it helps you: http://www.e-cigarette-forum.com/forum/nhaler/151096-darwin-evolv-799.html#post4061633

one thing you can think about with LR you have more Amperage, amperage is the power, if theres less resistence, you can put out more power. and the power is what drains the battery. i did HVAC for a while, and thinking about the concept is kinda hard to grasp, but this is what i always thought about that helped me out a bit

Ummm...I Beleive I made the right decision to buy one instead of trying make one...:laugh:

hahaha chief, yea good choice! i just got in some normal attys (all i had before was LR stuff) and i got some bobas bounty, anyone tried this stuff? im not sure if i like it or not, but i cant stop vaping it! anyways, my amps went down about half, so i should have a lot more battery life, the lr stuff i could barely get a day out of the battery, i wanna give the high ohmed attys a try

Yes this is the way to fly with the Darwin. See amp load discussion above and hence the reason I do not use 1.5ohm dual coils on the Darwin. You should see batt life jump by around 40% using standard resistance gear.
