So I did an experiment. I wrapped a 29 AWG wire 7 times to make a 1.8 ohm coil. Using an Evod coil which has a squishy peek insulator.



I had the Xvostick 510 base screwed in as tight as possible. Then I screwed in the coil loosely until I felt some pressure. It gave a resistance reading of 1.85ohm.



It fired okay, but it was loose, so I screwed it in further until it was good and tight. I could feel pressure at each turn and I could see the coil even lifted up a bit.

Now you see the same issue as you had, Kates... very low resistance reading.



When I took out the coil to examine, you see the insulator is still squashed.



So then I undid the Xvostick base using the allen key. I turned anticlockwise until it was almost falling out, and then clockwise half a turn for stability. Then used the allen key again to secure it.

When I screwed in the coil again, there was no feeling of pressure. It just stopped turning suddenly when the coil base met the Xvostick 510 base.

The resistance reading was now the same as the first time, without having to be careful about going too tight.


Here you can see the how such coils are wired. The negative wire sits on the outside of the peek insulator, and the positive wire sits within the insulator.



I tried also Subtank Mini and GoliathV2 with factory coils, and they also exhibit this issue when the Xvostick 510 base is too low (i.e. as you receive it). Unscrewing it fully and screwing it in a little, turning clockwise one and a half turns seemed to give the best balance of stability and sufficient contact.

MARVELOUS information!!! :thumbs:

No, I am not confusing the authentic Chels / Mini-Ecig with the various XvoStick Chinese clones.

I just couldn't understand why I am seeing the authentic XvoStick mods with both stainless steel and brass buttons and battery cap. I just assumed maybe the ones with the brass buttons and battery cap must have been an early version which has now been replaced by the stainless buttons and battery end cap.

Flt, I knew you knew. :) And to be honest, I'm not really sure of the history of the black with brass. I thought he had stopped making them. F2V's info is much better than mine. :blush:

From what I gather, the brass button version was/is standard and for a bit extra ($10), you can upgrade to the SS buttons - at least the last time I checked the Mini-Ecig site. And the Mini-Ecig site now shows you can get a blue and red one with SS buttons for $10 more than the black with brass buttons.


EXCUSE ME???? RED?????????????????????


Oh DPL! :cry:

I got the low reading when my xvo had no atty in it at the initial start up. When I fired the button (with no atty) the ohms moved between 0.07 - 0.1 (no error reading). Every atty I tried (I spent about 4 hours trying different atties, screwing in loosely, tightening & raising and lowering atty) and I got no change in the reading that was there when I attached atty. e.g. if I fired with no atty - it might go to 0.07 when I attached an atty the reading remained at 0.07 (and again no error reading). When I removed atties from xvo and tried on my provari they all fired straight away. One of the atties was a carto tank - will that have been the same? I did try all stock coil tanks (kabuki, carto tank, subtank mini, cero tank & aerotank mega) - I should probably have built something to try.... :(

Ah I must have missed this in your earlier posts; ohms should not be anything other than 0.00 if there is no atty. Perhaps Chels (or other mini-Ecig support person) also misunderstood.

Is this still reproduceable? Can you still make the mod show 0.07 ohm with no atty? Perhaps a photo sent to mini-ecig can make it clear to them there is a more serious issue than adjusting base height?

It's on it's way back :) They sent instructions - which I think was to double check I was adjusting 510 plate and they did offer if I sent the atty I wanted to use (with returned xvo) to set it up for me - but said it could take up to a month and there is no way I am being without my kabuki for even a day! I did read that the display will show the ohms of the last atty used so I assumed someone at mini had tested with a 0.09 - seems a bit low but I'm a tootle puffer so what do I know :lol:. (I may have misunderstood that from the dna40 instructions online (first time I've used one so the menu is a bit of a learning curve)). I never had a 0 reading from the first time I turned it on.

That red is absolutely gorgeous!!! Need to get my first one working properly first - before I even think about another :lol:

Le sigh. It's all I CAN think about now. I love red, but THAT red is just HAWT.

Le sigh........

I'm glad to hear they have done the right thing for you, Kates. I hope they will for all disgruntled customers; as DPLongo said, we should expect good support with any $200+ product.

Great pictorial, WiSK. It was definitely worth those 1000 words.

What does "peek insulator" mean (if anything)?

PEEK is a kind of flexible plastic which has a higher melting temperature than whatever stuff coil makers used to use. I believe the advent of factory subohm coils precipitated the need to use a better plastic for insulation.

The xvoxtick came in two (now three) colors. Black and blue (now red). Originally, all buttons were brass with brass battery cap. Chels then added the SS buttons and battery cap. Can still get the brass buttons: http://mini-ecig.com/battery_blocks/XvoStick

When I bought mine, SS was $10 extra (and still is)

In any case, the xvos at vapin art are authentic.
