KangerTech SUBTANK Mini

[DP2Raja]

1.2ohm OCC:

Coil: ID is .135", 5 wraps spaced, leg length averages .312" each (max), .227 (min), wire physically measures .010" dia, electrically measures 6.45 ohms/ft. Wicking density is very heavy and cut to .480" long.

.5 ohm OCC:

Coil: ID is .135", 5 wraps spaced, leg length averages .312" each (max), .227 (min), wire physically measures .012" dia, electrically measures 3.13 ohms/ft. Wicking density is very heavy and cut to .480" long.

Something interesting about the wire specs above. The 1.2 ohm coil has a wire diameter equal to 30awg but a res value close to 29. The .5 ohm coil has a wire diameter in between 28 & 29awg but a res value nearing 26!!!

Talk about throwing heat flux values off? How about out the window? Who knows what this mystery china wire is.

I just cannot get comfortable with pre-made coils not knowing what the heck the wire is. I need to control every aspect of my builds as much as possible when it comes to materials. I haven't heard of any one getting sick/etc with the pre-mades, but I get this little tingle that makes me uncomfortable about them...it's called doubt...mystery wire does that to me.

When i purchased this tank i thought it would provide better flavor than my Atlantis and it does. Secondly i thought the stock OCCs would last longer and i don't think they do. I was running the 1.2 ohm at about 16.5 w. I put it in Sunday and i only actually got 4 days out of it. I started getting frequent dry hits, though it tasted fine when it wasn't dry. I just hate the feeling i get from dry hits, so i put in a new coil. 70vg/30pg juice.

The old coil seemed gunked up, so i washed it with warm water and saved it. I'm letting it dry out. I might see if it has anymore life when the present coil needs replacing.

Worth a shot Joey!

Commented variously on Kanger's moving target of coil+wire dia's which I stand on. Latest batch of .5Ω OCC's mic ~.34mmØ (.5mm wire). Incidentally, I have versions of slotted and non-slotted (earlier ST, supplies) OCC bottom caps. Origin? Research lab or factory floor? Loved the video tho.

Good luck all.



p.s. Now where did I leave my magnetized forceps?

Are you saying the coils don't line up with kanthal, because I assumed they were using nichrome80.

The Delta II is pure stainless. No chrome on it. Works great if you get the rba section with it (extra $12, which sucks)

If you have issues with the Mini rba, you will just carry those troubles to the Delta rba. Technique in wicking is the same with both. The Delta II is harder to coil due to odd bend in legs required. You can by coils pre-made for the rba, but hard to find anything lower than 1.2 ohm. Both of these tanks (Mini & Delta) are great units. Well made, great air flow options and machined perfectly. Just my experience. I run a 0.5-0.7 ohm coil on these. Delta II at 28-32w, the Mini at 23-25.5w.

was eyeing the delta but w/my poor eyesight, vaping in lowlight conditions, chainvaping ~20-30ml/day filling that sucker would of been a pita thats why i went w/stmini

 

[DP2Raja]

I do understand that Vincom! The filling and the odd legged coil are it's drawbacks. But it vapes like a champ! I love switching between the two. Slight differences in flavor due to different diameter in rba enclosure and the higher wattage used in the Delta. These are pleasant differences using the same DIY juice.

Good catch Randy. It appears the numbers do line up with Nichrome80. Perfectly for the 1.2 ohm coil. On the .5 ohm the res/in lines up with somewhere between 28 & 29ga. Thanks for that R!!! Duh. Mystery solved....OCC coils use Nichrome80 wire.

And nichrome80 is non magnetic. Explains that too.

One more thing Randy, does Ni80 vape hotter than Kanthal in your experience?

 

[DP2Raja]

Twisted 28, 16 twists/inch, 2.5 ID, 4-wrap = 0.5 ohm.
Vapes like a champ at 23.5-25.5w on the Mini. Wick is KGD stuffed tight.

What are you people using to twist your wires so perfectly? Are you doing it by hand?

Kanger probably does use authentic Kanthal, but I agree that some vendors likely do not.

I use a drill and pliers, one end in the drill chuck, other end in the pliers, and go. One could do it by hand, but its quicker with a drill.

They are using electric drills. Fold the wire over (2 pieces), put one end in the drill, while holding the other end (with no slack) with pliers. Run the drill slowly and it will do a perfect twist all the way down.

Rip does a video on how to do it. As good as any other video (they all use the same technique).

I don't have much experience with nichrome outside of the OCC heads, but I do know that it is favored by cloud chasers due it it's lower resistance compared to kanthal. All things being equal, a nichrome 5 wrap is going to heat up faster than a kanthal 5 wrap.

Makes sense. For a given res Ni80 would be thinner and have less mass to bring up to temp. I have read where peeps have claimed hot vapor and off taste with it. I've never tried it. No need for lower res. My mini works great 1.1-1.4 ohm range. Vaporized nickel scares me anyway.

Shred, I use a drill with a hooked (home made) bit in it, loop 6 ft of 28 in half (now 3 ft) take the 2 loose ends in a good pair of pliers, stretch straight and tight, start the drill slow, speed up to moderate speed holding the pliers pulled away from the drill. You will feel the wire begin to shorten and draw toward the drill. you can stop at any time to measure the twists. When you are satisfied with the twists/inch and disconnect from the drill, the twisted wire should lay perfectly flat and smooth on a flat surface, not spring into a loop or have any coiling up action.

I must say I am loving this tank. Just got my wire in the mail from Temco, so I was finally able to do a 26 ga. 6 wrap build (0.7 ohm). It was so freaking easy (much easier than my Kayfun) because of the way the posts are setup with the little slot beside the screws. All you have to do is lay the wire there and screw it down. On the Kayfun I had to wrap the wire around those tiny screws, then tighten it down and hope and pray the wire didn't pop loose. I could sit there for 30 minutes sometimes with my Kayfun trying to get the wire under those screws. So annoying.

I think we'll see a lot of single coil decks copy this design. It's by far the best I've seen for ease of build. Kanger deserves some sort of award for this tank.

No kidding BigE. This really put my Kfuns, Rose 2, Aqua2...etc on the back shelf. The ease of mounting a coil is only one of the many reasons this puts the Kfun to sleep.

Good process DP2. I use the same process but use a ceiling hook in the drill. The kind you use for hanging pots. Instead of holding pliers I use my vise to secure the tag ends.

Noticed in your last pic how well the twists line up with your twist/in and coil ID. A real work of art. Looks kinda like a splined shaft coupler...heheee

My 2nd ST mini turned up yesterday and have a full size ST that I use for work with the prebuilt coils, both mini's I use the RBA heads at home, now all my other rebuildables have been put up.

I love how easy the ST RBA is to build on, and no messing around emptying tanks to re-wick and super easy and quick to fill up, been a long time since I have liked a tank so much to buy multiple of the same tank and only use them.
