Possibly looking for new VW device

[Crunchy2k]

The MVP2.0 is a great vv/vw device with no PWM (the is perceptible anyway) however it only goes to 11w. For $40 and all day battery life it's a great mod.

It doesn't only go up to eleven, it goes all the way up to eleven!!!!

The Provari isn't a straight DC device. It too uses PWM. But the frequency is high enough such that it doesn't matter much. The peaks aren't as high above the setting and the valleys not as low. It pulses at a much faster speed than most PWM devices which means a much smoother signal.

If you choose a Provari, you'd be buying a great vaporizer. Just don't get caught up in the hype and smugness that many Provari owners seem to be prone to.

That said, the sigelei 20W will provide a straight DC signal that is smooth as silk, is more intuitive to use, and about half the cost. You can also get 18500 and 18350 tubes for it to use on different occasions.

You won't go wrong either way, but the Sigelei is cheaper and provides more room to grow.

The provari has 800hz pwm that has an output filter that produces a clean DC signal on an o scope. In addition the Provari's voltage regulation is accurate to +/- .02 volts where as most regulated mods are accurate to +/- .1 volts. I am not aware of any regulated mod that is as accurate as a provari throughout its voltage range of 2.9 to 6.0 volts with no voltage drop off throughout the battery's discharge cycle. In addition the SegelI 20 watt just like the DNA20 has no buck circuitry and cannot regulate voltage down lower than the voltage of the battery.

It puts out a clean looking signal on an o scope, but were you to put a multimeter on it, you won't get a reading because it isn't a clean DC signal. It's a very fast pulse, but it's still a pulse.

That said, the Provari is a very good device because they did their jobs and took the time to implement PWM (and most everything else but the UI) right. Virtually no one will be able to tell the difference between it and a straight DC device.

Both these devices can buck down below the battery's voltage, just not below 4v. They are regulated at 4v and higher, but they compensate in different ways.

The DNA chips will simply dump battery power and act like a mech. The SX200 chip in the Sigelei 20W will actually raise the wattage setting and regulate at the lowest wattage it can in order to stay above 4v.

All that said, I have no idea why anyone would vape anything below 4v. I feel like I'm vaping air that low. Most of my vaping is between 4.2v and 4.7v, occasionally higher. I understand that people do it, I'm just not sure how they get anything at all from it.

The signals on an o-scope are virtually identical, the provari has a filter on the pwm output to achieve that flat signal, but what I was pointing out more than anything was the accuracy of the voltage regulation and the ability to regulate voltage down as well as up. Lots of people vape at less than 4.0 volts and the majority of vapers are using stock attys and you know as well as I that those people will never max the capabilities of a 15 watt device, let alone a 20 watt or higher device.

Here to sound off on the Sigelei 20w train. Absolutely love this device. I've had it for 2 months now and no problems whatsoever. Sturdy, reliable, good form factor, and good price if you compare it to the other DNA 20s. Couldn't be happier with my purchase. China gets a bad rap but they can make some good original vape devices.

The Provari no doubt a good device. I don't dispute that. That it can regulate voltage up or down is a very nice feature. I know that lots of people vape at less than 4v. You almost have to when using factory heads for Kanger/Aspire/etc tanks. And yes most of those will never get a real benefit from a 20+ watt device. All those are facts.

I'm just arguing that he can get a more intuitive device (the Provari is anything but user friendly when changing settings) for about half the cost.

I can understand people's complaints about the one button design, I get that, it can be aggravating at times. But that was a deliberate design choice by provape to limit possible failure points of the device. If there is one thing that the provari excels at more than any other regulated device, it's durability.

If you think the 1 button design on the Provari can be aggravating, you'd HATE the EPM VW MODs. They are the best vape I've had, and when I'm looking for a MOD to grab, the EPM is usually the one I grab. But it has 1 button and NO SCREEN AT ALL. All of the feedback from the device is via 1) various flashes from an LCD ring around the button, or 2) via the LCD ring changing colors. The device is not for everyone, but for those who don't care to see the exact numbers and prefer to solely vape-to-taste the device is genius, and the design is minimalist.

And though it's also a PWM device, like the Provari, the frequency is above that which anyone can detect the dreaded rattlesnake effect. It feels like a clean DC signal. So as I said in earlier posts, PWM isn't evil, poor implementations of PWM is.

I was adamantly against PWM devices until I used my EPM. I had no idea it was PWM until I asked.

I personally have no problem with the 1 button design, I've learned to deal with it, but it seems to be a common complaint that some people have against it.

Your language itself may be the reason.

An expensive device that you have to learn to deal with.

While the ProVari is a great device, I'm not sure if only having one button limits failures, as having three would mean that each one was activated fewer times. And yes I know they use very high quality buttons

 

[slappy3139]

Lol, yeah, ok, it's not hard to learn to deal with a minor inconvenience, when you look at the totality of the entire experience I have had with a provari. It is simply the most durable and reliable regulated mod I have owned. I just realize that nothing is perfect.

I speak from my own personal experience with many different regulated devices. In my experience my provari has never failed me in over a year and a half of ownership and multiple mishaps it has had to endure due to my carelessness.

LOL. I said that it was a great device of very high quality. I was just saying that I didn't buy that the one button design increases durability.

 

[slappy3139]

It's common sense that increased interfaces with electronic components add more possible failure points. That's just logical. Provape made a conscious choice to have a single interface to the chipset to reduce the possibility of failure.
