Kayfun mini clone? Does it exist?

[Mike757]

I'm too lazy to build coils and have been using these premade coil/wick thingies that cost a nickel each and work great:

I cut the wick just long enough to reach the bottom of the chamber after clearing the juice channel on each side.

I tried filling through the fill hole once, but now I just fill from the top, which is just as easy. If the valve gets damaged and stays open, I doubt it could be replaced.

Don't be so lazy, you're missing out on a much better vape then these coils can provide

Perhaps this is a silly question, so forgive me. I have a friend with a new Tobeco KFM, and man does it flood and leak. After a complete teardown, rebuild and removal of the obviously too tight clear tank, not finding anything out of the ordinary, it still leaked.

So I wonder: Should we be stuffing the juice channels with wicks in these things?

My new tobeco KFM leaks like a white house staffer too. Hates to be laid on it's side. I'll be adding a little more cotton, might help.

No, you should avoid blocking the juice channels. Your juice has to at least reach the narrow platform where your wick lies. But if you're getting flooding and leaking, that usually means too much juice is flowing into the "evaporation chamber" where the coil is. Check your o-rings starting first with the little o-ring at the top of the chimney. Somehow the outer chamber is losing it's vacuum and letting the juice level get too high in the inner chamber.

I fully understand what you are saying, and while these are all the things I normally think of with my full sized KF's, this little guy is so small that I think the outer chamber actually might have had a little TOO MUCH vacuum pressure -- too much for the mostly empty evap chamber with its smallish wicks. All the O-rings were in place and in good shape, my friend had tried the fill valve once, I told her not to mess with it again until we can do some good hot water tests with it, but the thing was still flooding like crazy.....until:

I used a larger wick and coil.

Flooding setup was: single coil 30g over 2mm RxW (ceramic), set at a diagonal with the wick ends laying gently across the juice-entry-steppes -- just like I normally do with the big KF's.

Non-Flooding setup was: Single coil 28g over 3mm RxW (much bigger ID ~3/32"), set perpendicular across the center island with the wick dropping straight down onto the juice deck, ends frayed out a bit AND with a few stray strands actually laying inside the channels. I also lifted the coil up nearly 4mm above the air hole.

It occurred to me that because the KFM is so small, it's vacuum pressure system might operate much like that of the standard ProTanks, EVOD's, etc... where the balance between flooding and dry hits is controlled mostly by the density and size of wick as it passes between the coil chamber and juice tank.

The answer in this case seems to be: more wick material down at the juice entry points to absorb those highly pressurized juice jets will keep this thing from flooding.

I think this is the key. Though in my case it meant using a larger wick 3mm vs. 2mm and raising the heck out of the coil.

Been using my ivogo for a week now. Great vape. Filled using both methods, no problems either way. Some leaking from where the plastic tank connects to the base, just a little seepage. Currently trying different o-rings. I've been running the same 1.9 ohm micro wicked with cotton all week, not one dry hit. Only issue for me is that it doesnt seem to hold much liquid, I find myself having to fill every few hours and thats a pain. If I had never had a taifun gs before the kf mini, the mini would be #1 to me. Only reason I like the gs better is the bit more juice capacity. Kf mini is a great piece of equipment though.

These guys say to only fill from the top (on original)?? Vaperev Shop - Kayfun Mini V2.1 - SvoëMesto - Rebuildables

Huh...well that's interesting. Thanks for the link!

Are these hard to rebuild because of the smaller size?

Not really much different than a full size kayfun in my opinion.

 

[Jazzman]

The Kayfun Mini 2.1 in short mode has a greater juice capacity than the GS (KF Mini 3.0ml and GS 2.8ml), and much greater juice capacity in long mode (5ml).

 

[bsoplinger]

But in long mode it's longer than many mechanical mods in 18650 mode

I put mine on a 1100 mah eGo, close to a foot total length.

My IVOGO mini has no leaking issues. I also never use plastic tanks. On the original manufacturers site the instructions list top fill as the first option. So..I top fill, but I top fill all my Kayfuns. Never had any issues.....

A little update on my Ivogo, after having it for a while, I've had zero issues, I don't vape anything thinner than 50/50, and most of the time it is pure VG, minus whatever PG flavoring, typically about 20/80, no dry hits, no flooding, no leaking no matter how I leave it lay.

Completely happy with it, and end up using it more than my full size Kayfuns. I also started using it in dripper mode, pretty nice as well, and still holds a fair bit of juice. Probably going to end up ordering a second one, maybe more, not sure if it is even worth trying the Tobeco, especially considering it seems to have issues the Ivogo does not.

EDIT: Only thing I've not bothered trying the fill valve, just pretty much used to top filling all of my Kayfuns anyway.

CC. Glad to hear yours is working good. I got a Tobeco and havent had any leaking. Is there other problems with them I dont know about? I seem to get pretty good hits off of it but at times seems to go dry and not wick well.. Just wondering if others have had that issue with the Tobeco.. I couldnt get the Ivogo but wanted to. Is there really a difference?

 

[ccwaters]

From what seems to be mentioned the clear tank sections are a bit thicker on the Tobeco, this does not leave room enough for juice flow, I cannot say first hand, just have the Ivogo, which as mentioned does not seem to have any wicking issues when using any of the configurations I've tried.

ok thanks. I seem to feel it is thick too and was wondering if that was the issue. There doesnt seem to be enough room for the juice to flow well.. I think I will put on the metal tube section and see if that helps and eliminate the plastic tank part to test..

Edit: My initial tests show that the clear plastic tube might be to blame. The metal tube in its place hasnt produced any problems yet as far as dry hits/
Will keep everyone informed as I can. Tobeco Kayfun mini, I wouldnt buy again because of this problem. Plastic tank section doesnt allow enough juice to pass into channels unless very thin. Maybe 100Pg would work, but my juices are 50/50 blends.

The metal tube section replaced the clear plastic one seems to have solved the problem, but you cant see how much juice you have left when using the metal one/ That sucks.

Wish I could just find a Ivogo tube, but cant seem to find any parts at all for either maker on this mini..

Put the Tobeco plastic piece in the middle instead of on the bottom. Works really well that way.

thanks Fear. Never thought of doing that.. Appreciate the tip!
