iTaste SVD and Nautilus Mini Combo Burning Up Coils

Hey everyone! I am new to this forum and a relatively new vaper. I have been vaping for about 7 months and am very grateful for e-cigs. I am having a really hard time understanding the voltage/wattage/ohms settings. I just don't seem to understand what they mean and how they affect my e-cig. I started with an iTaste VV and it JUST crapped out on me a week ago. I decided then that I no longer wanted to fool with anything with a USB port as they are too delicate it seems and prone to breaking. I also wanted something that would last longer than an iTaste VV and a backup so I went with the iTaste SVD so I could use batteries, which I thought made sense for what I needed. The SVD and the Nautilus Mini combo made my juice taste better it and I love the 18650 batteries as they last so long and I don't have to worry about my e-cig dying.

The ONLY problem I have is that my coils only last maybe 2 days. This to me seems like a settings problems. I get the voltage being adjusted changes the strength of the vape but the wattage and ohms I'm lost.:confused:

Here are my settings: 3.8 Voltage, 7.0 Wattage, 1.7 Ohms.

Does anyone know why the coils are burning out so fast or does this just come with the iTaste SVD?

with the SVD you can either set up the output to be watts (P) or volts (Uo) by holding the fire button and the "top" button ( atty on the right) it puts it into watt mode. if you hold the fire button and the "lower" button it puts it into Volt mode.... I find the Watt mode easier to use.

Once it is in "P" mode (watts) use the up/down buttons to get it to about 5.0P and start vaping there... see if you get satisfactory vape at that setting... if not up the watts 1 click at a time and test for taste/density. The coils in the Naut mini may be in the 32 gauge wire size and cant take alot of amps... thus you need to stay around 5-7 w ... if you continue having issues with coils going too fast, you may have to look into a better atty ( Trojan is a good one) works very well on an SVD...

Welcome I hade the same problem ok I tried everything and some things just do not make sense first of ohms law any thing over 8 watts 1.8 or 1.6 standard build for miny I run threw coils like juice at keeping under 10 watts when I first got it got a week out of coil the more I learned the less time I got out of my atomizers ok right on the side of every one I have ever seen says volts from 3.3 /5 the last two I bought were from local shop 5 bucks each I was getting some for 3.80 each here is were it all turned around I was low on money ...... last atomizer going south hit that dam thing with 15 watts at 6 volts damed if it did not start getting flavor turned it down to 11.5 watts and did not drop uunder 10 watts again got two weeks out of that one and one I had replaced before and it was still working the day the man I sold it to came to get it second thing happened I had never register the tank when the man that bought it did it came back as a clone I was getting the 3.80 atomizer from were I bought my tank so I am pretty sure they were clones to even thow the sealed box the aspire nautilus came in and the coils I boight 40 of them in a littel over two months the chep atomizer once they started to lose flavor they were just good for wasting juice vap but little or pore flavor even thow it comes in a box the looks aspire check it

Ok just a thought, you said in your blog post,
pg and I do not play well. So I use 80 vg 20 pg on a good coil]
are you sure your coils have actually failed? OR Could you just be getting dry hits / burnt taste due to the high vg and the nautilus mini just not wicking fast enough to keep up? Just an idea since it seems you have been through every other solution...

I am sure the coil has failed. It will not give me a dry hit, it will just be the flavor fades out until there is no flavor at all. If I let it sit for a bit when I pick it up again there is still just no flavor at all. It tastes like nothing, which is weird, so I'm sure it has gone out.
 
if you continue having issues with coils going too fast, you may have to look into a better atty ( Trojan is a good one) works very well on an SVD...

I have just figured out the hubby is having the same problem but he has an SVD 2 and he has it on 7 Watts. I have mine 3.7 or 3.8 Volts. I didn't realize he was having the same issue. It my be the mini can't handle it. He is also using a Nautilus Mini Tank.

I'm late to this thread, but there's no reason for a mini nautilus can't handle higher power. In fact, there are some (of us) who feel it doesn't really work well under 4.0v.

I run them around 4.0v on the iStick and the iStick is kind of mad... (too powerful, almost)...

my money is on your SVD being stuck in "Mean" output... or maybe that issue was resolved in the v.2. If the v.2 doesn't have a "mean" setting, then maybe it's simply over-regulating.

Here are my settings: 3.8 Voltage, 7.0 Wattage, 1.7 Ohms.

You can NOT adjust voltage and wattage at the same time, one determines the other with a given coil resistance. If your device is supplying 3.8 volts to the 1.7 ohm atomizer you're vaping at about 8.5 watts, not 7. Via Ohms Law:

Where P = Power (Watts), V = Voltage (Volts), R = Resistance (Ohms), and I = Current (Amps).

I = V / R
I = 3.8 / 1.7
I = 2.25 Amps

Now using the Power Law:

P = V * I
P = 3.8 * 2.25
P = 8.5 Watts

If you were vaping at 7 Watts on a 1.7 Ohm atomizer it would be:

P = V * I
7 = V * I

But we don't know I so we can't solve for V yet, but we do know R, and Ohms Law can help us out:

I = V / R
I = V / 1.7

...so we replace I with (V / R), or (V / 1.7), since we know R is 1.7:

7 = V * (V / 1.7)
7 * 1.7 = V * V
11.9 = V^2

Take the square root of both sides and we have:

V = 3.45 Volts

So on a 1.7 ohm atomizer, 7 watts or 3.8 volts are NOT the same and can't happen at the same time.

Basically your device is either running in Voltage Mode, where you adjust the voltage, and wattage is determined by the voltage applied and atomizer resistance...OR, you're in Wattage Mode, where you set the desired wattage, the computer measures the atomizer resistance and calculates the correct voltage to apply to get that wattage.

Here ends the overly complex lesson, I hope it helped some.

Mine is the SVD and my hubby's is the SVD v.2. I am not sure what a mean setting is and how would you keep it from over-regulating? Sorry I am not very knowledgeable on this. I thought that if you set it to 3.8 V then it is running off Voltage and not the Wattage or Ohms. Am I wrong or is it a combination of all 3?
