New Kangxin 50W TC device - Mini VF KX-50D: single 18650; LED torch; USB charge; multiple colours

[zoiDman]

Great news glad your enjoying it!!! My damn 510 connex was put in funky, has a bit of an angle in the battery tube. In which case my top piece is lifted up a bit, potiently becoming a big issue if I ever have juice leakage. Battery life is terrible in TC mod and not quite as efficent as a dna 40. I still like it alot and use the flashlight. Was gonna whip it around tomorrow but my rDNA came back so imma use it the next few days.

Sorry to Hear that your's came with some Issues. Is it something you can do a Return/Exchange on?

I was Holding my Breath on the LED Flashlight Feature. I read where the LED glows blue Every Time the Power button is pressed. Thought it might be a Big Annoyance. But the Way I hold it, being a "Thumb Pusher", I don't even notice it.

I like the Size and Feel of it. And for 50 Bucks, So Far-So Go. No Idea of what Battery Life I'm getting. I'll have to keep an Eye on that.

Right Now I think I have got to Take a Vape Break. I have been Hitting on it Non-Stop for about an Hour. Changing the Watts and Fooling with the Temp.

Kinda getting a Nic Buzz/Headache from so Much Vaping.

LOL

I'll live with the lean don't want to wait 3-4 weeks until I would get it back. If I could send it anyways lol. Either way it does its job and its cheap what more can anyone ask.

Something I do with All my Tanks and RBA's is to Shim them.

Some of my Tanks/RBA's don't sit Flush with all my Mods. So I punched a Hole in a Piece of MTB Bicycle Inner Tube with a Paper Hole Punch. Then Trimmed the piece so it was a Tad Smaller in Diameter that 22mm.

The Inner Tube Shim Takes up the Gap between my Tanks/RBA's and my Mods. And I don't have to Screw the Tank/RBA all the way Down to get a Nice Firm Connection. And the Inner Tube Rubber also has some Give to it. So it can fill Slightly Uneven gaps.

Maybe something like this is Would Help out with your Situation?

Have you considered (carefully) taking off the top plate? I did that to my green one when the 510 pin got stuck. That fixed it, though I still don't quite know how - the pin itself is inside the 510 enclosure and not accessible without dismantling all that, which I didn't do. but apparently just wiggling it about fixed it.

Anyway maybe you can see if there's a way to adjust it once the top is off - there's not much cable leeway but at least you could take a look. The top comes off easily enough.

Well I figured to try it out the other day but decided not to as I'm not used to such things. So I didn't try well up until 10 minutes ago. My initial thought when I first got it was that maybe a wire was trapped underneath. Sure enough that was the case. The white wire was trapped on top of the small semi circle bracket. So I tried to trap it on the other side of it, and managed to eliminate most of the gap. Still very so slightly there but unless you look very closely just the faintest gap, and that I can definitely live with.

Right On Shigura.

Isn't this the Coolest Forum?

Finally! got mine in today.. I have a similar gap going on but it's at the bottom where the battery tube is. The chrome caps apparently are not going through QC, the bad ones are not flat, I can see mine has a slight curve to it, giving me the gap. Tried to unscrew but stripped the head on a screw -wrong screwdriver- so i will be leaving it as is. no biggie tho. This Mini VF is pretty good so far!!

I just had something Strange happen to me with my VF Mini.

I am Happily Vaping away and Reading/Posting about Labels on e-Liquid bottles when all of a sudden I'm not getting a much of a Hit. I look at the Battery Gauge and it is Low, but this Doesn't seem Right.

So I swap out the Old Battery with a Fresh one and do a Test Hit. Very Weak. Almost No Vapor.

Great!

I have had this thing for Less then 24 Hours and it has Already Kacked. Just Fantastic. Gotta do Another RMA from FT.

Then it Dawns on me that I had Run My Tank Dry! But I wasn't getting that End of Tank Dry Hit. With all the Chain Vaping I did Yesterday, my tank was Much Lower than Normal. I refilled the Tank. And it is Back to Hitting like a Champ!

This TC Stuff is Blowing My Mind.

 

[TheBloke]

Haha Yeah it takes some getting used to, but is awesome!

Sounds a bit like the first time I made a nickel coil. It was also on a new atty clone I'd not used before which did not have great quality screws.

I screwed down the atty, checked resistance - 0.14Ω, fine - and did a test pulse in normal power mode (I didn't know at the time that you shouldn't pulse Ni200). Then looked down and the resistance had jumped to 0.4! WTH? It's those damn screws not holding the wire properly. Re-tighten, check resistance again, good, it's 0.14Ω. Fire. WHATT? It's 0.40Ω again! This is ridiculous, stupid atty. Tighten again, check, fine. Fire, argh!!

It was on literally the fourth repetition of that cycle when I happened to get distracted, and after seeing it at 0.40Ω again I did not immediately trying fiddling with the screws. Then I looked down a minute later and saw the resistance was back to 0.14Ω all of its own!

That's when it suddenly dawned on me.. Ni200 resistance rises as it gets hotter! Duh!

 

[zoiDman]

What's your Take, or anyone Else, on Ni200 vs Titanium Grade 1?

I got a Spool of Ni200 before my VF Mini arrived to see how it Coiled. And to Test it Out. It seems Very Flimsy and hard to Work with.

Another Member suggest I try Ti Grade 1. Said it was Easier to work with (which it Is!) and as long as you dialed down your Temp Limit (say from 420F to 310F or so) that it works well.

What do you think about all this?

 

[TheBloke]

I haven't used Ni200 for over a week now, and can't imagine I will use it again any time soon. I have been using Titanium, Stainless Steel and Resistherm. Ni200 sucks in comparison to all of them

Check out the Titanium thread and my thread on non-Ni200 wires: TC beyond Ni200: Nickel Purity, Dicodes; Ti, SS, Resistherm NiFe30; Coefficient of Resistance

I'll put up a calculator soon for working out the right temperature offsets to use for vaping Titanium on normal TC mods. But yeah as an rough estimation, set it down by 100°F or so. Lot's more details in the Ti thread.

Welcome to the wide world of temperature control, and leave those dry hits at the door. This happens frequently when I use any RDA, puff and puff like crazy just to open it up and still be half full. Its rather frequent to forget once you done it long enough. Haven't touched kanthal since, well not including leftover Atlantis coils before cracking open some nickel versions.

Yeah... I have been Chipping away at some of the Ti Threads here on the ECF. Still have More Reading to do.

So far the Ti build with the Temp set to 310F seems to be working Quit well. I'll probably do a Test build of Ni200 this Weekend.

Thanks for the Info.

BTW - I'm Really liking the Shape of this VF Mini.

When I 1st looked at the pictures, I thought that the Curve was on the Wrong Side. And that it would feel Better in my Left Hand. But the Shape is actually Great for Right Handers.

The Groove in the one side leaves a little Air Gap between the Mod and my Right Hand. So I don't get that Sweaty Palm Syndrome when I hold the Mod in my hand for a period of time.

I think it feels great in both hands for that matter as I switch-hit with both hands. Mostly left handed when I vape probably due to me smoking with my left 95% of the time (driving). So I broke down and bought some Ti wire from envycigs, rather expensive for a small amount (15ft) c'est la vie. Also picked up a Segatank RBA head for my Silo Beast when it ships early next week.

Hey guys,

I have just done some battery charging tests, the first time I've used the in-mod charger.

• I took two EFest 3100mah batteries which I had drained from 4.2V down to Weak Battery, one in each of my Mini VFs.
• I then took extra vapes on one battery until I got them nearly identical voltage, one was 3.366V, the other 3.373V
• I then charged one in my EFest LucV4 charger @1A, and the other in a Mini VF from a 2.5A charger (meaning it could pull whatever amps it can at maximum.)
• I timed them together and found the EFest was faster, but not by a huge amount - I therefore estimate the charging is about 0.8A in the Mini VF; to be confirmed further
  • I don't have a reliable overall comparison yet because I screwed up the last half hour of charging in the Efest, putting it to 2A by mistake.
• I discovered something troubling: after about 4.5 hours, the Mini VF was still showing charging. I removed the battery to test its voltage and found it to be 4.22V
  • I need to abort the test now as it's 5am, but I will repeat it next time the batteries are drained.
  • But I do find it worrisome that it took batteries quite a bit beyond 4.2V and was still trying to charge them beyond that.

As it stands I do not think it is recommended to use the in-mod charger, at least not if you want your batteries to last. But I will test again soon, including letting it carry on longer to see how high it goes (well I will abort at 4.25V if it gets there!)

With Multiple Mods have Problems with Onboard Charging, I have Adopted the Practice of Never using the Onboard Charger on Anything I own.

Thank you for Posting your Testing. And Please let us know what you see when you do that Second Test.

Anyone experience inconsistency in the temp control? Sometimes i do get dry hits.

 

[Azarias]

Anyone has the Kangxin VFMini and the Heatvape Invader and can compare them?
I wanted to try TC after my next paycheck and I'm not sure wich one of these 2 to buy.
Like the looks of the VFMini, the Invader would be a great mod for work.

 

[aikanae1]

I just bought one of these from GearBest. First purchase from there so I don't know how long it'll take. I figure I'm in no rush. I just knew that no matter how well tc was explained to me, I'm not going to "get it" until I experience it.
