In the display, when you dry fire it, you will see the watts in large numbers, then a series of smaller numbers along the top. The first is the voltage. The next is the amps (I believe) followed finally by the ohms. When you fire the Darwin and electricity flows through the atty there is a relationship between these four numbers. By changing the settings of the watts you change the other numbers.

For example currenty I am using a tank on my Darwin at 5.4 watts which results in 4.1 volts ~ 1.3 A ~ 2.9 ohms. As I crank up or down the watts the other numbers change.

Like you I am not an electrician and all this means bupkiss to me. What makes a difference to me is the satisfaction of my vaping experience, which is subjective to me and what pleases me. So I start at the lowest watage and slowly move up and down until I have the amount of vapor cloud I like without any burning or burnt taste through the vapor. slowly that changes as the level of juice is used up in the tank and that changes where I like the settings.

The beauty of the Darwin is that I can play with the settings making the entire tank match up to my liking throughout the day.

As SheerLuck said, the Darwin pretty much does all of this for you. The basic formula is P(watts) = I(amps) x E(voltage). P=IxE, it spells pie (I like pie). As has been said here (and there) several times, an advantage of the Darwin is that the Real Deal That We Care About, is how hot the thing gets, and how consistent it is. For our use here, watts = heat.

A battery puts out volts. Depending on it's construction and age, it's voltage will often go down throughout it's discharge. Modern batteries can manipulate this with regulation to make them more consistent. An atomizer/carto has a fixed resistance when it is made, and it changes as it ages. This means that as the voltage and resistance changes, so does the watts (heat). Depending on the variables this change could be taking place over a period of weeks, or over a period of days or hours, or all of the above.

While I am as much (or more?) of a gadget freak as the next guy, a big monster battery on a PV won't make it taste different, unless it is a different voltage (thus altering the watts, and the resultant heat). A big monster battery will last longer, and provide a more constant voltage throughout it's discharge cycle.

Altering the voltage, along with differing resistance of atty/cartos most definitely changes the vaping and taste characteristics. This is the beauty of the Darwin. You set a basic wattage you desire (the big number), and Darwin continuously monitors the voltage of the battery, the resistance of the atomizer, and juggles things many times a second to try to give you the wattage (heat) you have it set for. You can change the characteristics of a particular juice or atty/carto, by just spinning the knob. You don't have to swap parts or carry a screwdriver to do so.

You can check Darwin's math, by multiplying the first number (voltage) times the second number (amperage) and it should approximately equal the number with the large font (wattage). It may vary by a few tenths or hundredths, but this isn't lab grade test equipment. Other factors like juice on the connectors will slip these numbers a bit.

I have an applemint juice I have been enjoying. Turn the wattage down, I taste more apple. Spin it up, I taste more mint. I can mix it on the fly. Say for example that my favorite taste for this juice is 7.5 watts. If my atty/carto dies and I put in another one, it will definitely be a different resistance. Darwin will change everything as needed to make the new one operate at 7.5 watts, I don't specifically care about just the voltage, it's only one variable. Very cool stuff!

EDIT/addendum: The last number (of the small ones at the top) is the resistance of the atty/carto, displayed in real time. This does not change while moving the knob, it is more of an informational display. It does change as the atty/carto ages. These are all intertwined, as Voltage = Amps x Resistance. The whole vaping experience (electrically speaking) is basically a combination of these two formulae. If you change any one thing, everything else changes as well. P=IxE and E=IxR. While displaying this stuff is a plus for electricity geeks, perhaps Nhaler/Evol should just label the knob as "Flavor".

Delivery of the juice consistently is another thing that changes the vape and flavor, but that is mostly physical things and not part of the electrical stuff.

I am noticing on my Darwin I received yesterday that the battery meter is showing about a 70% charge. I had read where the battery meter stayed at full until it was actually at 50% then it showed correct battery life and went downhill quickly after that.

Maybe the battery meter issue is fixed? I'll find out tonight as I continue to vape on it.

Definitely needs some sort of charging indicator.

Repent, you may just need to charge it overnight first, has it ever displayed 100%? It's like many gas gauges, it is not very proportional. As long as it has some charge to start with, you can vape with it while it's plugged in, as it functions well as it's own pass-through.

it had about a 70-75% charge. I put it on the charger for about 4 hours. When I pulled it off it showed what looked to be 100%. Next time I charge it I'll put it on the charger overnight, as I typically do with my batts.

nano, your post of "volts 'n watts" was excellent and informative, even for the not so geeky amongst us (like those of us who call it 'Pixies', right Sew?).

If you and Nebula and some of the others get together, oh boy, I'll need a "I have a Darwin. Talk to my like I'm 3 years old" thread.

In the words of the infamous Ski, Vape Happy!

Thanks Kat. I am new to vaping and still have much to learn in that regard. Thanks to everyone here and all of ECF I am standing on the shoulders of giants. I am fortunate that I spent the time to learn from ECF's collective years of experience, and went to Darwin as my second PV. I have been sticking bobby pins into electrical outlets from an early age, so I get bonus points/forgiveness for going overboard on the electrical stuff.

I know Darwin is not for everyone, but as fast as the PV industry is changing, it is surely a big milestone. There has never been anything like it. There will just as surely be variants.

It's not magic, but Pixies is as good a term as any. Change the big numbers to what you like for your juice and atty/carto/tank combination, make note of it, done. I do not have a formula for converting Metric Tinkerbells to Watts, but I am sure there is one. :closedeyes:

Repent, possible misinterpretation about the meter. There have been several posts on the battery meter, mine among them, and they were not intended to provide any sort of exact scale to the meter readout. The intention is/was merely to provide a rough idea of what to anticipate from what the meter shows. Think in terms of the various gas gauges on different cars. Each reads differently. Some gas gauges will drop very fast (perhaps half a tank after the first 100 miles) while others may stick up near the top (perhaps still showing full after 100 miles). The amount of gas in the tank is what it is but some gauges read differently. The point about the Darwin guage is that it tends to be like the latter gas gauge example and shows full for the first several hours of use and then can appear to drop more quickly.

I may have been the one to say that when you see the gauge start to drop you may be at about half battery life. That was not intended to be any type of accurate measurement but rather an extremely rough estimation. Basically, when you see the meter starting to drop, you might want to pay a little more attention to it if you plan to be away from a power source for any extended period of time with anticipated heavy use on the device.

Hope this helps clarify any possible confusion my previous posts may have caused.

Hey Neb;

thanks for the info. I do understand what you mean about the gauges. I've had several cars over the years that had gas gauges that would swing pretty wide when I turned a corner, for example.

What I'm seeing on my Darwin is a steady decline in battery meter as I use the device. I had read previously in a post (don't remember whose it was, not important) about users seeing anomalies in the battery meter. I currently am observing a gradual decline in battery meter as I use the device.

I charged the unit overnight last night. When I put it on the charger it was at about 50% battery strength. Now, I'm at 100% strength on the meter. As I use the device today I'll again watch the meter to see how it behaves.

I am not sure if I can consider myself a "heavy" vaper but when I charge mine to 100% it usually doesn't even get below half by the end of the day. I don't even need to charge it every night but sometimes I do because I don't have a backup mod.

This has been discussed, I am just parroting it... One of the biggest things we can change to affect Darwin battery life is the resistance of the atomizers. With the regular 'battery on a stick' PVs, lowering the resistance of the atomizers will make it hotter, and change the vape and taste. The Darwin doesn't need this since it can adjust the wattage with the knob. LR atty/cartos will make Darwin put out more amps to reach your desired wattage, this will hit your battery harder.

Higher resistance atty/cartos will use less amps to get your desired wattage. You can swap them around, and see this in the display.

Panky, I'd be too paranoid to not have a backup! Bought a few and after the Darwin, well they were just ok (of course they weren't vv/vw which didn't help). So, I bought a back up Darwin :) Have a 5v juice fed on the way which will be my mod for long trips though.

Well, I guess that I wouldn't be totally screwed if I ran out of power. I do have my ego batteries and an LR 306 lying around but that would be a dire situation :lol:

Hey guys..got a few concerns
***1 put on an atty and display went CRAZY. does this mean atty is dead/bad?

***2 put on new atty (901) to replace broken one above and it keeps tasting burnt!! I washed it, blew it out and dry burned-still burning taste, and burning juice real quick (at 6.0 setting!!)
i feel like such a newbie. argh!!!!!!!!!!!!!!!!
