vmax...3rd post...

[Kremppie]

I am really not happy with the vmax. If I didn't have a Provari, I would think I just didn't know how to use it, but they pretty much work the same. It works, and it doesn't, it burns hot, and the bottom is round...so it tends to fall over. I don't regret buying it (although I would give it away), but I am wondering if anyone else is having the same problem with them. I may just have a bad one, but I still paid $128 for it.

Any idea which generation you have? I'll just assume you are starting it at 3v and working up, but maybe whatever carto or clearo or whatever you're using on top is a super low resistance and you're dumping a ton of power across it?

If you wanted to give it away I can PM you my address, would even send you a crap ton in juice for it...lol

I bought it the second week in June of this year. My silver bullet is not as harsh as this vmax is at 3v. It makes my eyes water, and is very strong. I am using the AW batteries, and have tried four different sets.

 

[Kremppie]

It is silver and I have the box it came in. It is just too much for me. What are you using?

That's just how things that use pulse width modulation work. Check out this review.

I use a lavatube as I am too poor for a provari.

I do know the first couple versions of the vmax they had issues with them putting out MORE voltage then what it showed on the screen. I would head over to the vmax section of the forum, the people that post there know everything there is to know about the different versions of the vmax.

I understand that the use of pulse width modulation (PWM) is confusing, but, can't be the source of the Vmax issue. In fact, Provari V2 uses PWM and has no complaints like this. Something else is amiss.

My paint is coming off really quick, my button needs to be pushed extra hard it seems too. I enjoy the hit and it is a very sleek mod. I just think I may have also gotten a faulty one. I don't even use it that much either, I have 2 other "go to" mods I use before the Vmax. I can't say I dislike it, I'm just a little disappointed.

Really, I thought the Provari used some sort of boosting not PWM. But either way I guess I should say things that use PWM often have this issue. I have a Young June Lavatube 1.5 and it's the same problem but not as bad as a Vmax.

PWM is a very common technique for manipulating voltage in the electronics world and has been around for a long time. Vaping is just late to the party. Provape and others seem to have figured it out. But what PBusardo identified in his review of the VMax indicates that not everyone using PWM has figured it out consistently. Maybe there's just a number of bad Vmax's floating around and he got one of them.

 

[Kremppie]

I did just watch PBusardo video and I think I understand a little better. What I got from it was...not a bad device...but it does burn hotter. I don't like anything (at this point) over 4v, except the silver bullet, which I don't understand at 6v. I can put the same tank on the vmax on 3v and it tastes burnt. I hope that makes sense.

 

[AndyInOC]

Hmmmmm maybe get your hands on a carto (or whatever youre using) with a higher resistance. From my reading here on ecf before purchasing the Vmax I know that the 1st generation ones were rumored to be much hotter & wilder so that could also be part of it. Seems as though my 12mg nic liquids are much more tame on mine than the 18mg is so that could be part as well. Even at 3.4v with 18mg it treats me as though it wants to rip my throat out Lol.

Also as a secondary thought, I don't have tons of knowledge about electrical current bit I do know enough to be dangerous. I'm fairly certain that one issue many vmax owners run into is that they are used to having a VV device that won't allow as much amperage to their coils as the vmax will. If im not mistaken the provari & silver bullet are both 2.5 or 3 amp devices while the vmax allows up to 5 amps. That is substantially more current allowed to pass through the coils and it will make a huge difference in a 3v comparison across devices.

After all.... It's not the voltage that bites you, its the amperage that said voltage carries that gets you.

 

[Kremppie]

I think that would make a lot more sense. I just think it is very strong...to the point I cannot use it.

 

[Iusedtoanalog]

Evie, What resistance carto(etc) are you using on these devices??

I love my Vmax. Use it much more than my Provari. I have not scoped out the Provari yet, but I believe it uses PWM in a totally different method than the Vmax. I think it uses it on the input side of the regulator, where the Vmax uses it on the output.

The Vmax puts out around 8v at its on cycle, then adjusts its off time to give you an average around where you have set it (I do think it still is a bit high if I remember correctly though). It does not play well with single coil anything's that are LR. I personally do not put anything single-coiled below 2.5 on mine, as it does seem a bit harsh any lower.

If it came down to the Provari or the Vmax I would probably keep the Vmax if I based it on performance alone.

Just my input!

[Kremppie]

but, my point is...I can switch the same tank on another battery or mod and I love it...the vmax is too hot.

switch to a single coil carto or some other attachment around 3ohm resistance & you will fall in love with the vmax as well, its just a different beast than what you are comparing it to.
