Actually if I had to guess I would say that is the 50W flask I have from SXK. But it's definitely too risky lacking any further info.

Worth an email to the vendor to ask for full specs- no idea why they would include such little info.

Also buying a batch-1 SXK Flask is not necessarily recommended as they have resistance readings that are too low, affecting TC. It can be counteracted via Nickel Purity, but it's not ideal. There's now a batch 2 with an New Atomizer question. That also appears to read resistance too low, but possibly not as much - we're trying to figure out details of that at the moment in the Beyond Ni200 thread. And I've contacted SXK for more details.

Hopefully know more by tomorrow. Personally I wouldn't buy an SXK flask right now until we can confirm if the batch 2 is improved on resistances and if so, by how much.
Ah, ok. The nickel purity is pretty fascinating to me. May just look into a zero clone instead, although I'm kinda turned away by the single 18650 part of it. Lol

There was 60W NP flask linked a few pages back on a US site for $99.99. You can also get them from a Chinese reseller on the chinese-only Taboa site, which you can access through BuyChina.com - that worked out to $74 delivered. Search this thread for posts by @yo han for the Taboa link, then paste that link into BuyChina.com and follow the instructions. They buy it from the Tabao guy, send you a picture to show they have it, then forward it to you in the US or wherever you live. They charge a small commission on top of the Tabao price (included in that $74 I mentioned)

Besides that, you can order five direct from SXK and then sell four, perhaps at a large profit - if you're so inclined. They work out to about $55 each that way, including shipping and all fees.

Otherwise maybe Focal will have them in a week or two or four.

Bloke, did you ask Gecco if they could ship by Ems Epacket for a cheaper rate when you talked to them?

No, but I did tell them the shipping made it way more than I wanted to spend and his response was to knock shipping down to $25 making the overall price $90 instead of $95. I didn't pursue it any further than that.

However I don't think EMS/ePacket is necessarily all that cheap, normally - maybe only for Focal/FT/3F because they get some special and huge discount.

On that BuyChina.com site I just mentioned they have the option, to the UK, of China Post ($12), EMS or DHL - the latter two are both about $24, literally only about $0.50 in it.

But you're right it might be worth asking Geeco just to be sure.

Hey @TheBloke i have been getting the same 0.04 misread as well. I didn't know that the problem was the flask until I read your post. But now that I did that's exactly how low mine is reading in Kanthal & temp. protect modes. So right now I am using the Kanger ni200 OCCs. Should my NP still be set at 70?? Also have some 28g that should be here tomorrow. How do I figure out NP setting for these?

So, from my reading last night, it sounds like I will need to change the 510 on my new Kangxin flask? FDV v3 shorty?

If you don't want to f@k with the bouncing resistance you should change. But carefully, don't short the 510 positive post with the battery positive post, cause your chip will die. ;)

I've quoted your post into my "Beyond Ni200" thread, replying in this post. We've been talking about this for a while in that thread and I've put together a Google Spreadsheets calculator which can calculate NP values for you automatically for any case where the resistance read by the mod differs from the real resistance of the coil - both SXK's too low reading and general too high readings in cases of 'static resistance', ie the resistance in the atty which gives a too-high reading over and above the reading of the wire itself.

Check that post and the calculator and I can answer more questions there.

I will post an update in this VF thread in the next day or so once I know some more about what's happening with the Flasks specifically. There's still some doubt as to whether SXK have improved the resistance issues; there's definitely a new chip out there in some new Zero and rDNA mods, and one person reports much better resistance reads, others report it's still too low but possibly not as bad as we're getting with batch 1 devices.

I'm collecting reports from various people with different SXK mods, and I'm emailing SXK tonight - once I have some more details I'll put an update in this thread so people planning to get flasks will know what they should be receiving and whether it's worth waiting another week or two before buying.

Well I just got my 60 watt FT SXK flask, after 4 hits I'm already thinking about changing the board.
Resistance is .05 lower than actual and I'm getting "temp protect" almost immediately.
I took this TGT II off an Evolv powered mod the will but didn't give me "temp protected" ever with this atty.
I got the "new/old" atty question upon firing atty first time.
I came in a nice box.
Not too happy
Here's what I'm running for a coil, 28 gauge annealed ni, 11.5 wraps, 2.5 mm id, 0.12Ω @ 28 watts/450 F


Oh wait, I see the SXK is set to 300 F, just got up, hardly any coffee drank yet....DUH
OK, set to 450 F, vapes much better but still hitting TP

Have you checked your nickel purity setting?

Look familiar?

The 510 socket looks like FDV v3 shorty on both ends.
I'm not changing the board here yet, just looking at the job.

You can use my new calculator to adjust NP for the offset of resistance that you have. On the v1 batches (without New Atomizer question) it ranges from -0.04 at 0.10 to -0.07/8 around 0.40-50, up to -0.16 above an ohm. Sounds like it has not been improved in your flask as we first hoped it would.

I'd be very grateful for any more details on resistance comparisons against known-good mods at various resistance readings.

Anyway here's the post announcing the calculator. You select the wire you're using, put in the target temperature, the resistance the mod reads, then what you think is the actual resistance (adjusting for static resistance in your atty, if you want), then it tells you what NP setting to use to get an accurate TC at that target temp.

Nickel Purity / Static Resistance calculator

Lot's more discussion on the SXK mods in that thread, particularly last 4-5 pages.
