iPV Mini?

[Flt Simulation]

As to Watts Displayed being incorrect - Doh, never thought to mention this as I assumed anyone with any understanding of ohms law would realize it. I also made the mistake of thinking people would work toward their SWEET SPOT which is most enjoyable and has NOTHING to do with Displayed data.

Enjoying my mini rather than going .... over display readings.

Flt Simulation - how old is your Fluke and has it been Re-calibrated and Verified.

Your absolutely correct in that the best way to go about this is just to set the watts to whatever YOU like the best.
I just did this test for the hell of it since I had nothing better to do at the time ... Posted it just for the conversation is all.


The Fluke I used is a new unit that I borrowed from my neighbor.

Ron,

Its not just about the display. If you have a .6 coil and the ipv mini is reading it as .3, it wont fire. So for sub ohm vaping, it is a much bigger problem.

Hi, did you subtract the internal resistance of the Fluke?

No I did not ... The internal resistance of the multimeter I just measured as 0.1 ohms ... so this is the new results


I select 11.0 watts on my Mini ... With my coil attached, the display screen shows the coil resistance to be 1.7 ohms, and the voltage to be 4.3v

But, reading from the Fluke multimeter, the coil is actually 2.0 ohms (after subtracting the multimeter's 0.1 ohm internal resistance), and the voltage supplied to the coil is really 4.5v when firing in the DC-DC mode.

If we use Ohms Law, we find that a 2.0 ohm load that is fed 4.5v is actually burning at 10.1 watts.
__________________________

So, the results show that we had set 11.0 watts into the Mini, but the Mini really only supplied 10.1 watts to the coil .... That is 0.9 watts lower than we had actually wanted to get from our Mini.
__________________________

In this case, if we indeed want exactly 11.0 watts to our coil, we would need to set the Mini at 11.9 watts (+0.9 watts)
__________________________

Now your Mini may not be indicating your coil ohms 0.3 ohms too low, like mine ... but you can now see how this effects the watts of power it's [really] feeding your coil.

did you miss this????????????????

okay, i'm going to make this suggestion to all ipv mini owners.
If your mini is reading substantially incorrect, i.e. .3+/- ohms different than an accurate test meter reveals.

everyone should target the same rep. For maximum effectiveness.
Include place of purchase and a brief description of the problem.

Contact your selling vender with the same information and ask about correcting the issue.

 

[Raguvian]

Err, to be honest, I don't really care what the screen says. I just use the numbers relative to each other, not as an absolute figure. As long as my Mini can give me the vape quality I want, I don't really care if it's inaccurate, especially given the price point.

Plus, I'd rather the mini read too low than too high when measuring ohms. Better safe than sorry. Even if I'm doing a low ohm build for my mechanical mod, I'm going to use the Mini to read the resistance.

 

[cjpeltz]

did you miss this????????????????

No. You had said to just ignore the display and vape where you are happy. I was pointing out that it isnt that simple when you are using sub ohm coils. Whether or not I contact the vendor is not relevant to clarifying to you that this is more than an issue with the display.

 

[capitaomorsa]

You can always do one more wrap in the coils just to guarantee that it works in the ipv mini, in the case you are rebuilding sub ohm coils in the limit. Just a suggestion.

Mine is reading accurately in 4 different coils I have, but I don't have coils below 1.4 ohm to confirm the lack of accuracy bellow this value.

Is your iPV Mini really giving you the watts you set in the display? > >

If your Mini is like my Mini, then you are getting less watts of power to your coil than what you set in the display, and the reason why this is true is because, like my Mini, the ohms of resistance that the Mini displays for your coil is actually lower that what the correct ohms of the coil is.

These are my findings, using an accurate Fluke multimeter:

I select 11.0 watts on my Mini ... With my coil attached, the display screen shows the coil resistance to be 1.7 ohms, and the voltage to be 4.3v

But, reading from the Fluke multimeter, the coil is actually 2.1 ohms, and the voltage supplied to the coil is really 4.5v when firing in the DC-DC mode.

If we use Ohms Law, we find that a 2.1 ohm load that is fed 4.5v is actually burning at 9.6 watts.
__________________________

So, the results show that we had set 11.0 watts into the Mini, but the Mini really only supplied 9.6 watts to the coil .... That is 1.4 watts lower than we had actually wanted to get from our Mini.
__________________________

In this case, if we indeed want exactly 11.0 watts to our coil, we would need to set the Mini at 12.4 watts (+1.4 watts)
__________________________

Now your Mini may not be indicating your coil ohms 0.4 ohms too low, like mine ... but you can now see how this effects the watts of power it's [really] feeding your coil.

You can't run the mini according to actual reading off other devices.
You need to just turn up or down to until you find your sweet spot.
I've tested the vape on other very accurate devices.
If you are building sub ohm you should build higher for the mini than you would on another device.

That basically what I have been saying .... If you like 11 watts on another device (that is very accurate), it's not going to be the same as 11 watts set in the Mini, because the Mini will not give you 11 watts when 11 watts is set in the display (because the Mini is reading your coil's ohms wrong to begin with).

The only reason I made this test is to prove that when you set the Mini to a certain watts on the display, you more than likely won't actually get that many watts to your coil.

And like you said, you really need to just turn the watts setting up or down until you get a vape your happy with (no matter what it says on the display)

I was just proving a point that the Mini is NOT accurate ... that's all

I bought samsung 25r batteries but am curious if my other batteries are good enough to use in the mini as well. ???

From what I can tell online, the top Panasonic battery has a max drain of 6.8 amps, so that would not be suitable for the Mini. I can't tell what the bottom one is but I'd stick with the 25R.

Thanks. I haven't used the bottom one in some time. I have to go back in my order history to remember what it is exactly... :-/

I am randomly experiencing erratic high resistance readings on my iPV Mini and it's happened with a couple of different RTA's. It's sometimes as much a 1.0Ω or higher then the actual value. Of course, when you fire it like this, it's a rude surprise.

Has anyone else had this trouble, and if so, what's the fix? Most of the time it works very well.

 

[Ringo®]

Is it all the way fastened? Have you tried any other atomizers?

 

[VaPreis]

It has happened with my Aqua V2 and a Lemo that is single coiled.

In fact, it happened on my first vape with the Mini using that Lemo on Christmas morning.

While the Aqua V2 has never seen use on another mod besides the Mini, the Lemo is routinely used without issue on another device.

 

[fredrikstad]

I don't think what you mentioned will effect the way it Vapes in anyway. Only how it Looks.

Should you Return it? I dunno? If it Bugs you every time you see it. Then yes. I would. If it is just something that you see and it doesn't Bug you, then I probably Wouldn't.

No, it doesn`t bug me at al. I just read somewhere that it would decline the perfomance or taste or what it was I read. But thank you, that was great to hear. I will not send it back then.

 

[Flt Simulation]

I was getting erratic resistance changes on a Kayfun Lite coil when checking it with an ohmmeter ... Come to find out that one of the screws that attach the coil was loose.

How that screw got loose is beyond me ... They were both tight when I initially installed the coil.

 

[fredrikstad]

No I did not ... The internal resistance of the multimeter I just measured as 0.1 ohms ... so this is the new results

Can you test it in PWM mode to? Amy Lee at Yihiecigar told me that that mode was more accurate.

Hi, did Amy answered to the RMS question?

Hi, did Amy answered to the RMS question?

No she did not. She kept asking if I was a modder, and how many chips I was interessed in . It seems like she didn`t understand my English, wich is understandable (pun intended)
