I think I've narrowed down my next device Vamo V5 or Sigelei Legend 15W

[twolostminds]

I've been reading, reading reading, watching video's, thinking about the difference between what I want and what I need in a device.

I love my MVP 2.0 and was thinking about getting another one to replace my 2 vv 3.0's but I have decided to go with something with replaceable batteries instead of a disposable. I want 20 or 30 watts but feel I only need 15 so I am looking at the Vamo V5 Stainless & Sigelei Legend 15W.

I like the 3 buttons on the V5 but I also like the idea of adjusting V and W in 0.1 increments on the Sigelei. I also like the bigger screen on the Legend but can anyone tell me if the font sizes are bigger or if one is easier to read in bright light than the other?

For toppers I will primarily be using Aspire nautilus and Kanger Aerotank's and am thinking about getting an Igo W to start playing with building my own coils. I also have a couple T3S's and CE5's that I would like to use as backups. I know this question is going to open up a can of worms for some but what topper would you all suggest works best on these models?

Battery questions: EFest IMR seems to be what most are recommending but I am wondering if I should get 2X 18350's or 1 X 18350 & 1X 18650. I think I remember hearing or reading somewhere that 2 X 18350's work better in some devices than a single 18650 but can't seem to find it in my notes.

Have I forgotten anything to consider? What are your thoughts?

In the past those Legends had a problem where if you shook it the menu options would change on you. Not sure if that has been fixed but here is the video. I hear the Vamos are pretty good.

Aside from that have you looked at the Zmax v5? I love mine.

For a topper, I would recommend a Kayfun, especially if you are thinking about getting into rebuildables. Have you tried rebuilding a ProTank/Aspire/Nautilus coil yet? If you haven't you should give that a try.

As far as the mods go, the Vamo at least, isn't what I would recommend. I consider it more disposable than the MVP, and the MVP is a good device. Have you considered the iTaste VTR? It can use the tanks you currently use, has the box form factor, and takes replaceable 18650 batteries.

I can't speak for the legend, I've never used one of those.

The Vamo V5 is a very good APV for the price, especially because it has a 5 amp limit which is better than most APV's. It's weakness is the soft 510 threading. You may want to get a flow regulator just for the threading, not the regulation. They cost about $8.

It's other weakness is that 33.3 hz chip. I killed 2 V3 Vamos...I'm not really sure what the V5 offers as an upgrade as far as durability goes, though.

Are the buttons still a weak point?

I recently got a Sigelei Legend. You DON'T have to 'shake' it anymore to change the settings. Just tilt it.

It vapes better than my SMOK ZMAX or my Lambos.

This is the latest version. I think that there were too many complaints about the 'shaking' thing so Sigelei changed it so all one has to do is just tilt it to the left to go down in voltage or wattage, etc., then to the right to go up in settings. Clicking the button takes one to the various menu settings.

The OLED screen is feature-packed and show all the info in one screen. The "Puff Counter" though only activates if you vape it for 3 seconds or longer. Any less than 3 seconds and the counter will not change it's count.

Some of the things I have read say that the Stainless Steel V5 doesn't have the 510 thread issues, can anyone confirm this? Also, if it has the 33.3 chip in it that would be a deal breaker for me. I just don't like the way 33.3 devices vape. Definitely leaning more towards the Sigelei.

Haven't tried rebuilding yet, but have ordered some kanthal and wick materials to play with.

I just found the info on the Vamo V5, it is a 33.3 chip
I"ve also found that the original Legend that needs shaking has the 33.3 chip but can't find info on the Legend verison 2. Does anyone know what chip is in it?

 

[Jugband]

I have the Vamo v5. The threading only lasted me a few months. I have several mods, this is the only one I had thread issues with. I do agree with the Kayfun for a topper. Got that also, you really can't go wrong with that.

I thought I'd heard most general APVs out there still used a 33.3 chip. What're the issues with it?

No problems with them, there is just something about them that makes me not like the way they vape. Haven't been able to put my finger on it...but just a preference.

I own a Vamo and an SVD. The SVD is superior. My guess is that coming from an mvp you will be disappointed with the vamo unless you are just looking for a cheap back up.

There is good relevance to the frequency argument. The word that you all are missing is Joule. It is a measurement of heat defined as:

1 watt x 1 second = 1 joule(J)

First the VAMO (or any other 33Hz mod)
Assumptions:
Set at 4.2VRMS (50% duty cycle)
2.0Ω Coil

Calculations:
1 second / 33Hz = .030 = 30 milliseconds(ms) cycle time

30ms * 50% duty cycle = 15ms pulse duration

We know the the VAMO fires at 6V during the on time.
(Ohms Law: W=V2 / R)

6*6 / 2 = 18w

Now that we have the duration and the power, we can calculate the joules.

18w * 15ms = 270 millijoules(mJ) per pulse.

Provari (or any other DC output)
The Provari's frequency is irrelevant. It's a flat DC voltage with a little bit of ripple to it. We don't have to figure out the pulse time because realistically, there is no pulse. So all we have to do is figure out the output in joules for the same duration and compare it to the VAMO.

Same assumptions:
4.2v and 2.0Ω coil.

(Ohms Law: W=V2 / R)
4.2*4.2 / 2 = 8.82

8.82W * 15ms = 132mJ

So we end up with 270mJ per pulse compared to 132mJ over the same duration. If we look at the heat output over the period of a full second they are relatively equal, 9.0J compared to 8.82J (the error is due to 4.2VRMS not being exactly 50% duty cycle). However, burnt juice, even if only 15ms at a time, is still burnt juice.

By increasing the frequency of a pulsed output device, you are shortening the pulse duration and thus lowering the joules per pulse. You will never get equalization compared to a DC output, but eventually the frequency will be high enough, and the joules per pulse low enough, that you wouldn't be able to tell the difference.

Another interesting note is that as the duty cycle increases (higher voltage/longer pulse duration) the difference in joules between the two devices will decrease. Meaning, by setting both devices at 5.0v the difference in the heat output will be less than if set on 4.2V.
