Joyetech Evic VT 60 Watt

[JeremyR]

You asked for some thoughts about this and I have a few...

The eVic VT is pretty clearly designed for low ohm, high wattage, high airflow type of atomizers. It is engineered to be used primarily over 30 watts. In temp mode, it doesn't even go lower than 30 watts.

Pbusardo loves Kayfuns..... They are not designed for the type of usage that the eVic VT is designed to provide. I have a kayfun V4, But I wouldn't use it on my eVic......Sure, it will *work* with this set-up, but it's not a very good pairing.

The eVic VT is even painted like a *Muscle car*..... It visually says "This thing is fast and loose". A clue to the intended use of the device.

At the low pricepoint of the eVic VT, people shouldn't expect it to be perfect for *every* vaping situation. It's the Ford Mustang of mods.... Fast and affordable, but low on luxury and all terrain performance.

I have had a couple issues with my eVic VT personally, but it's still my current "go-to" device. I've used it all day, every day since I got it. It's not perfect, but it's great considering the "bang for the buck".

I appreciate Pbusardo's extensive testing of the eVic VT, but the source has to be considered when assessing his review. He is a professional reviewer. He receives most items for free, and gets paid to evaluate them. He has nearly unlimited access to devices, so pricing is no concern for him or his evaluation. He is looking for engineered perfection, and affordability is not part of that equation. It's not a surprise to me that he gives it a "thumbs down"......But he is also the type of guy that would buy several authentic Kayfuns at $200 a piece.

Use his scientific findings and compare them to the price of the device. Disregard his "rating" and decide for yourself if it will do what you want for the price it's offered. For me, it's 2 thumbs up.

Excellent post! The car analogy was on my mind too!

No biggie! The doctor just wrapped my head in an ace bandage, gave me a bottle of aspirin, and told me to stay off it for a week. [emoji40] he said something about resultant strain from too many years in a middle school classroom?![emoji54]

 

[P.H.]

I really wish they revise their coil head for this tank. BTW today I rematch rip tripper unbound fir this set. I notice his coil head got 4 holes, mine only 2. What about u guys?

I don't know if anyone has answered your question. The thread is so long and I am so late in finding it! When I ordered our vic vts I also ordered a couple boxes of replacement Ti coils, labeled eGo ONE CL Ti. They do have 4 holes. I just changed over to one and can't tell a lot of difference. Still getting muted flavor but I do use higher vg ejuice.

Has any MTL Vaper compared the the vape experience of standard Kanthal 1Ohm head with the Ni/Ti heads?

Just wanted to point out that Busardo did NOT give the Evic VT a "thumbs up" in his initial review. He gave it a "wait for Evic to make improvements". Now that Busardo has investigated and confirmed the fact that there the unit is going to fire at 30 watts for over half a second and fire above your selected setting for over a full second unless your setting is already at 30 watts or more, he has changed his "wait" to "thumbs down".

Offering of advice to always use the device at 30 watts or above is not a solution; it's just a description of those who would not be affected by the problem.

Thanks BigBells, my bad. I misunderstood Bursado's video and you are absolutely correct.

I couldn't agree with you more. If we could simply trust a manufacturer's specs and device to perform as intended, we wouldn't need to wait for reviewer's opinions or have to be masochistic beta testers. However, working all the kinks out of a device takes time, especially if it contains new-to-vaping technology. If we're happy waiting 12-18 months for new devices, we could purchase reliable new devices at probably 50% greater cost. If, however, we like this new every few months cadence we've been experiencing, vapers will continue to have to pay to be beta testers.

What I truly don't understand is why Joyetech, after pioneering the concept, failed to spend a few extra dollars to make the VT's firmware user upgradeable. It would have made everyone's lives so much easier. This can be looked at as either added value or simply a reward to early adopters for being beta testers. After being burned a couple of times on inexpensive devices, I will no longer be an early adopter of devices that are not user upgradeable, cheap or expensive.

Not having a software upgrade port is indeed a big negative. But, the way I am rationalizing this is the fact that at such a low price point one can wait until upgrades are incorporated (if ever?) and then buy just the express battery pack for $50 or so. That would not be much worse than purchasing 4 Sony quality high drain batteries for a box mod. Am I trying to justify being an early adopter? You betcha! I think many looking to the future of this wonderful vaping pursuit would likely agree.

After having this mod for a week and trying the stock coils, I'm now using my lemo 2 with an 8/9 wrap Ti coil, and bamboo rayon.
Temp 460f, 32watts, 0.41ohms coil.
It's a fantastic vape, producing thick clouds of vapor.
It's doing what I paid for, I couldn't be happier with it.
The high watts use a lot of juice, but that's to be expected.
The biggest difference was using bamboo rayon, it's the best wicking material I've used so far.
It absorbs the juice like nothing else.
Temp protection kicks in if I hold the fire button without vaping, as it should.
For a $60 mod, it's doing everything I expected.
Kanthal, nickel, and titanium, all work as expected.
What more can you ask for?

Where con you obtain the bamboo rayon. I would like to give it a tryout. Thanks.

I agree with you completely. Thanks for the reply. I am now using the included tank and it is workng very well considering its weak juice flow to the wick. I look forward to getting a build on my STM rta when I get the wire needed. I also have a number of Smok VCT versions that i look forward to using with the nickel and titanium coils. Thanks for providing your experiences. It is a great little device now that I have a better understanding of its capabilities.

@JeremyR could probably answer that question for you...

The thing about VW mods-- why they work so well-- is by controlling the wattage used, they always apply the same amount of total power to the coil for however long you have the fire button pressed, thereby giving you a very consistent vape. Within limits, they don't care about the atty resistance; they just apply the right current at the appropriate voltage to burn X watts-- wherever you set it-- for as long as you hold the button down. State of the art being what it is, there are some practial considerations. The board can't deliver more power than the batt can provide, or so much current it melts. There's usually a limit to the ability of the board to measure the atty resistance; if your coil falls outside those limits, the board can't calculate A x V to give you the W you want.

No offence, but I don't think so. Vw mods are voltage regulators, not current regulators.

When you select the wattage the chip first measures the atty res, then it calculates the appropriate voltage to apply to the coil so that the coil can draw the correct amperage to produce the desired wattage.

The mod has to know the res of your build so that can it can calculate the maximum voltage it can apply before over currenting the regulator.

Unquestionably true in practice in most if not all cases, but it doesn't have to be. It could be built the other way; it's just, in practical terms and with the chips easily and cheaply available, adjusting the voltage is easier to do. But there's no reason a current regulating board couldn't be built to modulate power output from a constant voltage supply rail, or one that regulates both current and potential, if there were some good reason to do so. They just don't because it would be bigger, more expensive and suffer more I^2R losses. My point in the section you quote-- perhaps I phrased it poorly-- is the board must know both Amps and Volts to calculate Watts; this is true regardless of whether the current is limited by the board itself, the battery C rating; held constant or variable. To offer an example, an array of FETs shunting the current path through an array of various value current limiting resistors in series with the atty would change the current value as resistors in series are additive. I can't imagine anybody actually building that, but it would work if they did. And the bottom line is, the math doesn't care and the board needs both.

Right, none of our vw mods are built with current shunts because they would be inefficient and produce heat in the mod.

Again, the board only needs to know RES to calculate everything. Volts are applied based on wattage selection. Its using the V^2/R formula to determine wattage; not the I*V formula. Amps and watts values are calculated by the board and neither is monitored or regulated.

Maybe we're saying the same thing but it sounds like you are saying amps are measured. I don't believe they are.

Please forgive me if I'm beating a dead horse, I want to make sure noobs get what's going on inside their vw mods.

We are saying the same thing, for the same reason I*V yields the same result as V^2/R. But I take your point; and bow to your expertise. In fact, I have no idea how the various regulated boards actually do what they do. I've never built one, or taken one apart; a number of them are proprietary in any case. I only know what they do. For the n00bs, and those who don't speak Ohm's Law, there's more than one way to skin this particular cat. I'm sure cigatron is correct. His way is easy and slick and easily accomplished with currently available chips. FWIW, I wasn't trying to suggest the actual boards in practice use one or another particular formula to calculate wattage. That's variable, and can be done a number of ways. I was hoping to convey the relationship between potential, current and resistance, and how this relates to battery life, not describe the function of actual mods. If this has resulted in confusion, I am apologetic and refer you to cigatron's guidance.

All good suprtrkr. I really have read way too much on vw and tc chipsets here on ecf and other sources.....I need to get a life bro!

Lol, no harm, no foul. I'll bear this in mind, if I ever decide to buy the chips and make one I'm mostly interested in mechanicals, or rather e-mechs switched with FETs, because I hate clunky, gigantic buttons. But Evolv is going to release their 200W TC board Real Soon Now, and this is tempting. If I can't get it to cook, I'll look you up. Pleasure to talk to somebody who understands

I got the power mode switching thing today. Luckily my build was too low ohm to fire in power mode. It was a .07 nickel build on my mutation x v3. It was hitting solid then as it heated up after a few puffs I got nothing and looked and it was in power mode giving a low ohm error. That issue is a real problem, if my build was a bit higher I would have gotten a brutal dry hit or a small fire in my atty. I had to wait about 20 minutes for it to cool down and read correctly again.

I love the eVic but that is a scary problem. I have two of them and may just stick to the stock tank now. Seems risky with my RDA and doesn't seem to work right with my subtanks. With the subtank it's either weak puffs or dry hits. The stock ego mega tanks work great with it. I don't get why it struggles so much with everything else.
