This is where some people fail to do their homework , they just buy on what's popular . I got a dna 30 clone and prefer my MVP for Pro tanks , I Clears , Aerotank's etc...

DNA 30 is much better for dripper's and other higher wattage applications but imo most people who vape still prefer standard Clearos and tanks that DO NOT require high wattage.
Agree that those that use tanks, standard clearo's don't need higher wattage. Variable wattage devices also have other benefits other than just higher wattage that really appeal to non-drippers. It's not just about more watts imo....

4.17V is a pretty good value for a fresh battery under load, especially given that there's electronics between it and the coil.

But let's get theoretical. The maximum voltage a Li-ion battery can be charged to without suffering damage is 4.25V.
4.25^2 = 18.0625. Divide by the resistance. of 2 ohms... 9.03125 watts. That is only 0.3watts higher than retird suggested. The resistance that should cause a DNA chip to output 11W with an ultra-fresh battery, with no internal resistance, is 1.64 ohms.

But with an internal resistance and other losses of 50 milliohms, that 11W will result in a voltage drop. It turns out, after some horrible algebra, that the minimum resistance that can be supplied with 11W is approximately 1.59 ohms. So there is no way a DNA should be limited to driving a 2ohm coil at 11W. 9W maybe, 8.7W maybe, but 11W no.

Google Ohms law.


You like your fruits at 9W ? I prefer 7-8W. Point is the sx3000 is a stepping stone. Unitl they develop an economical chip that can down regulaet DC, the Provari is still the go to device.

So use a cooler coil, or have you still not googled ohms law?


Comparing a provari to a DNA, SX and related type device is silly. Their strong points and intended purposes are completely different. If you didnt do your homework on the device (you know, by googling it) that is simply your fault.


And I vape fruit flavors at over 50w sometimes, so I dont know what that has to do with the price of tea in China.

The MVP outputs DC, and it is much, much cheaper than the Provari.

DNA and SX output true DC, but most of them do not down-regulate. The SX350 does down-regulate, just like the MVP.

The Provari makes a good deal of sense if you are in the USA, but it is still very expensive. Outside the USA it is insanely expensive and loses almost all of its advantages.

I ordered a DNA based DNA-30 Tube since they finally came out in a tube form factor. It was in haste a bit as I didn't relalize I con't turn down the power with it. I think a freshly charged battery comes off at 4.7V. I mainly just use aerotanks. I wanted something with better voltage reg than a buzzy SVD and less expensive than a provari but now I am having second thoughts. On a fresh battery the lowest a can go is 11 watts. Maybe I should have stuck with kicks cause I find 11 watts burns the juice in the aero tank with a 2 ohm coil. I don't get sub ohming at all, seems like fried grease would be the result. How am I wrong about this?

On a genuine DNA you will be fine at 2 ohms and get the full range of wattage. It's a misconception that a DNA cannot regulate under battery voltage, it can regulate a significant ways under battery voltage.

I have a Sigelei 30W and run my Aerotanks on it all day. I build single coils from 1.8-2.5 ohms with cotton wicks. Vape from 8.5 to 12 watts. Tastes great.

Now the Magma is another story. It is incredible on the Sigelei, but I don't always want to drip.

I have a Sigelei 30W also, Battries don't fit and it drains the battery over night when not in use. Obviously slapped together. But with a KFL it gets the job done and pure DC for the price isn't bad.

What is economical? The SX350 chip can down-regulate DC. I can buy one for a quarter of the price of a Provari and the mods are about the same price as a Provari.

I can buy an MVP much cheaper, but it won't grow with me like an SX350.

I think you need to look up provari prices I just got a blem with a discount code for 117 no tax free shipping. The sx350 chip is $70 by itself.. Pre-installed In a mod more like 250. So I can buy 2 provari for that price. Provari are not expensive I can't understand how someone will buy a vtr for 110 when u can get a provari for 150.

It can be a pain to have the 7 watt minimum on some of these devices.. I run into it myself with the DNA30 from time to time.. ;)

I would just hold-out until the new iTaste SVD is available in September. It will be sporting a genuine Evolv DNA20 chip, programmed for Innokin, which will buck-down. ;) More than likely other Innokin devices will be sporting Evolv chips in the near future. The ProVari 3 will probably debut around the same time. From the rumors I've read, it will be a 24 watt device, and most certainly more expensive than the SVD 2.

Both are on my radar for sure... :)

Sub ohming requires wicking that can supply lots of juice for an extended vaping session coupled with free air flow. I tried a DNA 30 mod yesterday at Stormy's. The tank on that particular mod was a Nautilus Mini with the air flow adjustment ring removed and the holes drilled out to a large diameter. It was like breathing normally! There was virtually no restriction. The display read 23.5 watts and It produced a cool vape that was full of flavor and huge clouds of vapor. All that came through the drip tip from my Kayfun I used on her DNA30 and it has a tiny hole on the end. Go figure!

Provari Mini £160 (~$260)
Provari Mini V2.5 [VE435-ST3] - £160.00 : Vape Escape

SX350 £49.95 (~$80)
YIHI SX350 CHIP

The only SX350 box mod I can track down is the The Atlas by Tatroe Mods for $234. Yes I know that would be internationally shipped and the Provari is locally sourced, but it's early days and there aren't a lot of them about. I would expect to soon find box mods available for about that price locally.

Also consider as I said in my other post, "the Provari makes a good deal of sense if you are in the USA, but it is still very expensive. Outside the USA it is insanely expensive and loses almost all of its advantages." I have no particular interest in kit made in the USA. It is far more interesting to me for it to be made in the UK or even the EU. A lifetime warranty is of no use if I have to pay and wait for intercontinental shipping. I know you are in the USA, but I am not. Our experiences will vary.

wow i cant believe how much of a premium eu has to pay. didnt mean to jump down your throat before. i guess il consider myself lucky i just cant believe the price goes from 150 to 260.

I paid $160 for my used green provari and $45 for my VTR, prices must be fluctuating. The VTR comes close to the provari in taste. For work I prefer the VTR because its pocket friendly. They both have excellent voltage delivery and no rattle snake buzz that IMHO affects flavor.
