Eleaf Istick

[scaredmice]

What baffles me is folks say they can't hear it. THEN there are folks that say they can here the 33Hz in their cartos but can't hear an 800Hz hiss. These are well known audible frequencies. Play 800Hz through their car audio at 100 Watts or so and see how fast the old fogeys bail out of the car screaming they've been deafened.

Well, that day I was dumber than usual.....

I swapped Hertzs and MegaHertzs.....

Don't forget that for the most part of the 'higher-than-33-Hz' mods, they output an almost flat DC current, the ripples in it are negible to hear, even in the craziest resonance with the atomizer.

istick and that first wave of cheap Chinese VW output squared PWM and in that case, if the pulsating effect of the current resonates with anything......

....¡rattlesnakes on my atomizer!

(Here we lack of experience about rattlesnakes, apart from western movies....., so if sometimes any of my atomizers dares to resonate, I would probably do not hear it....)


I won't spoil your image of me and I'll post now some charts I've posted on a Vapers Spanish forum. If they serve someone, good. If not, fair enough. I won't write down now the maths behind them, I do not want to get in the list of the 'top 10 most wanted'.....

But if anyone dares.....


In the next charts, the translations from Spanish are:

'voltaje promedio' = Average voltage (the one in the istick screen)
'voltaje efectivo' = Root Mean Squared voltage, V_rms for its friends.... the one expected.
'potencia mostrada' = Output power as it is shown on the iStick's screen
'potencia real' = actual power output

The charts 'clearly' show that with high ohm resistances you can vape between 7 and 11 W, but you should set your VW on screen between 4 and 10 W, more or less.

Good advice, KTMRider. That's what most of us have been doing and loving the iStick. The problem worsens for people vaping very low watts, however. Firing a displayed 4.5W into 2Ω on the iStick (3V) is actually dissipating almost 9W at the coil. That's 50% more than his target. While he may find himself happy with that, would you suggest he gamble $35+ on that experiment? It would be so much easier, yet less entertaining, if the iStick just did what it and Eleaf/Joyetech say it does.

Because 9W is a No Go for the Clearos I use. And My Clearos taste Fine on an iStick.

If he finds himself happy with a setting on the istick, does it really matter if it's really 9w at the coil instead of 4.5w? And that would be 100% more than his target

The point I'm trying to make is that some are creating mountains out of molehills. I've used RDAs, RBAs and Kanger tanks (Aerotank and Protank mini 3) and they all worked fine on the istick. I like a cooler vape so high wattage/volts don't appeal to me and that's not why I bought an istick. I liked the size and the display. There were enough people on this thread and elsewhere (reddit and youtube) that I got enough info to want to try it out for myself. I read about the potential issues and still had some questions but I just ordered to see for myself. I was worried about firing from sleep but it does that just fine. There were no surprises and I really like this little device. I have no problem recommending this to anyone, newb or not. Ok, maybe not to sub-ohm'ers but they know better. If the MVP works for you, this will most likely work better for you. If you think $35 is too much for an experiment to get a better vaping setup, then pass on it. Your loss but I think you'd be missing out on a great little device.

Aw Man... Some of us Love Math.

Hit us with a Big Fat Integral. Or at least, a Partial Derivative or Two.

I would consider myself a low wattage vaper and the istick works great for me. I really don't see a problem as it will go down to 2w (though I don't know at what ohm). I didn't buy it because it went up to 20w. I got it for the form factor and cool little display. I never had an issue with power output on the MVP, it was just big and the fire button wasn't the most comfortable to use.

I beg to differ, KTMRider. The iStick is incapable of firing below an effective 4.17V. To obtain 2W, one would have to use a 8.7Ω coil. A 3Ω atty is required to get near 6W (5.8W @ 3Vavg).

This is why some people, though loving the iStick for their personal use, are unhappy with the engineering Eleaf put into it...

I couldn't read through this entire thread...so I'll just ask. Does the ego adapter work ok on it? And, are some getting decent 510 connectors or are they all finicky 510 connections? Disregarding the lack of a spring on the 510.

Damn, this thread does move fast!

I've had no issues with 5 different toppers. My Kayfun 3.1 usually has an issue on my MVP and V5 but works fine on the istick.

Just FYI for those who are thinking about buying their first iStick.

After two days of use my battery indicator showed only a single bar so I decided to put it on the 1 amp charger included in the full kit. It took about 2 hours and 45 minutes to reach full charge.

I consider myself to be a low-power vaper. I came from Kanger eVod batts - both vv and non-vv that are advertised to be "regulated" at 3.7v. I've been using the iStick at 6 to 7 watts using either an IGO-s RDA (currently 1.7 Ohm) or a Mini-Protank 2 (2.1 Ohm, rebuilt).

Quite pleased with the iStick. Great value IMO.

I guess you are right that we expect thing to perform up to standards when we buy them but after a while you get so many let downs, you come to expect it. I know when I bought my GM car last year that I didn't expect 16 recalls this year. Since I have been vaping every month something comes out that is the next best thing since sliced bread. The sigeli 50 watt box mods had to go back due to pin connections. The Seven 22 can't use Kanger tanks due to pin alignment it seems like no one tests anything except thru the public. The only thing I have seen beta tested is the Provari 3. I definately know I shouldn't mention windows for computers and how that is released. So for 31 dollars I am happy and not smoking. Now if GM doesn't give me something that drives right soon. I going to say bye to buying from them.

Euphoria Vapor in Middleburg Heights. Staff is friendly and really know their stuff, and take the time to answer questions. They have a full taste bar and a huge selection of juices. Last week they opened a store in Fairview Park (they don't yet stock the istick at this store) so take your pick based on your location.

Thanks Trailz. I did stop in the Fairview Park store on Monday and found out they didn't have it yet. At least I know they were telling the truth when they said they Middleburg Heights store stocks it.

Definately been looking at them since the last recall

To obtain Watts from average volts: (Vpk²/R) * duty cycle

(5.8²/2) * .52 = 8.75W

 

[Stosh]

The short answer is that the voltage/wattage numbers for power displayed by the iStick are pretty much useless as far as determining how hot the vape will be compared to other devices. Adjust the iStick's power level to taste rather than using other device's power levels as a reference.

I've found the iStick to be a cooler vape then my VV Gripper and a warmer vape then my MVP, but about the same as my mechs (with a fresh battery), if I set each tp 4.2 volts. Every mod, every model has slight differences, the numbers just give you something to remember for next time after you find your sweet spot.

See here's the Thing.

Just like at the Beginning of this Thread, people started Saying that the iStick was Hitting harder than a Number on a Screen says it should. Or compared to another device like an MVP. When I Take a Clearo off my iStick that is hitting fine, and then put it on MVP @ 9W, it taste Burnt.

Not saying the Math Isn't right. Just not what I'm seeing.

The OP's target was 6W. You suggested trying the iStick at 4.5W to get to 6W...

Let me repeat that I'm loving the iStick. But I'm vaping RTAs and rebuilt Kanger heads. Stock 1.6 & 1.8Ω single-coil Kanger heads get hit with a minimum of 10.9 & 9.7W respectively. In my Protank 2 w/ AFC, the stock heads would not produce a pleasant vape.

This is simply my personal experience. I am beginning to wonder if Eleaf is experiencing bigger issues with quality control or if multiple versions of the iStick have left their manufacturing facility.

 

[aldenf]

I know the voltage reading is off, but Ive never used anything with a wattage reading. Is watts off in step with volts or is the watts reading correct?

The Watts display is inaccurate to say the least. Start at the lowest setting for your atomizer and go up until you find your sweet spot.

 

[Steeldragon]

May you wonder how many facilities are making them,

I just wiped it down with a microfiber cloth, no solution on it. I cut it from a sample sheet of DiNoc from 3m. Is your sheet a DiNoc from 3m or a knock off? The adhesive backing is pretty strong once it's applied and hold very well on my MVP. No issues on my istick either.



I got mine off of ebay. It is carbon fiber but it is very thick, which makes it resilient when i bend it around corners. Also the glue is not that strong.. Thanks for the link... I'll give it try...

I have no problems with my tanks connecting. I didn't get the ego adapter with my first iStick but the adapters I had already work just fine.

To obtain Watts from average volts: (Vpk²/R) * duty cycle

(5.8²/2) * .52 = 8.75W

BTW - It's Interesting to compare Watts Made from Constant Voltage to Watts made from this Equation => (Vpk²/R) * Duty Cycle when R is Bounded from 1 to say 4.0 Ohm.
