I don't know for sure, but looking at the threading on the bottom picture, it does not appear to be the Robbot version. The threading looks like 20:1 threading, not the coarser Z2 threading. Again, I am just guessing based on photos.

Exactly! .. so yea, I am a bit bummed too. At first I thought it may be because I was running sub ohms, but the lag was the same with the 1.2 ohm build as well. Sigh .. So I much prefer the 30W version over the 50W at this point. And the firing delay bugs me a bit more than I thought it would too..
The build quality on the 50W is on point, but the chip ... eh, I prefer the 30W chip.

That is absolutely not the Robbot ZNA .. first I doubt that you will ever see anything from Robbot Tech on that site, and for two the Robbot Tech ZNA both the 30 and 50W cost much more than $55 WHOLESALE .. so not possible.
FYI, I have never ordered from that site, but I hear its a janky site so beware ...
thanks.. guess i was just hoping id found a bargain
Ok.. Just receive my zna50, as I m a noob in high wattage devices, I m not sure about its chip performance.
The zna looks solid, but does have some uneven edges which can be solved by filing it. The zna was in a quite dirty with machine dirt n screen was with scratches... I drop in my fully charged 18500 flat top.. N it turn on! Wow.. It can take 18500 flat top without modification. That I was happy about! Will use it later for more feedback.

Both I'm afraid, im very disappointed in the chip and internal build quality. looks and feels great on the outside, but internally its shoddy at best.Are you getting that the 4.2v on display or on your meter? One negative that I have also realized is that the 50W does not boost that well on a low battery in 18490 mode ... I am a bit disappointed in that because a) I only use it in 490 mode and b) my 30W Robbot is so good on a low battery. I vape until cut off without even noticing .. with the 50W I definitely feel the lag at about 35-40%
Been vaping it at .6 and 17W, then I switched to 1.2 and 13W, but output still lags at 35% .. It may be better in 18650 mode, but I don't really like this form factor in 650.
The chip is reading 0.3ohms under so 0.7 on the atty becomes 0.4 on the device, which means 0.6 would be the lowest I could fire as it reads 0.3.
Ive now got it to output the correct voltage for the ohms its reading but its still only putting out 30watts when set to 50, and I had to resolder the positive atty connection to achieve that.
Shocked at how crap this is badly soldered and insulated.
Im not even sure I want to put a dna40 in it now due to the awful connectivity inside. so dont know what I'll do with it. I'll look at again after Christmas. The good news is I'm sold on the form factor, but thats about all.

wow now im glad i didnt order the 50watt version. I am sold on the all steel zna though. how available is the 30 watt version still?
Mine is working fine though. Lemo with 0.9ohms on ohms meter..: my zna50 is reading exactly 0.9ohms.

Overall, I have to say that I agree with your disappointment in the 50W .. I am not a fan of it, which sucks because I really liked the minor tweaks in the outer build quality on it .. My vape is frustrating at best ..
The sad thing is that when Robbot first asked me if I thought they should do a 50W version, I told them no I didn't think they should (true story) .. I am going give them feedback on all of this. They had cut their teeth on the ZNA 30 which is the first electronic device they ever tried to make, so IMO they should have just continued to improve on that .. I LOVE my ZNA 30 from Robbot, from how it performs to how it looks ... this one, Ugh I should have passed on

Oh honey I am waiting for DHL to deliver my 1:1 Kayfun V4 from Robbot right now! I am ready to kill DHL because I thought they would have delivered it by now so that I could post some better pics ... FC's pics ARE AWFUL. Did you order one? Sylvia was nice enough to send me one as soon as they were ready to ship ... now this I have way more confidence in, but of course I will need have to reserve true judgements until I use it.
If anyone wants a better look at the Robbot Kayfun clone, go to their FB page, there are much better pictures there.

I skyped Doris yesterday and gave her my thoughts and opinions on the 50W and told her that I didn't think she should continue to stock it. She said they still had some 30W's in stock ..

My resistance reads accurately too ... the only problem I am having is the serious battery lag, and having performance drop off too quickly after inserting a new battery. I don't vape anywhere near 50W, so I can't speak to that aspect of it ..
Ive tried everything to get the ohms to read correctly, I'll do some more tests after Christmas now, I tried the chip on its own and its still out by the same.Overall, I have to say that I agree with your disappointment in the 50W ..

My original plan was to put a dna40 in there so I will probably do that in the end.
I'm going to rebuild and replace the internal contacts too as they are not up to scratch for me. The actual mod and the threads are really nice and that's the only thing I cant replace/redo myself. So with a bit of time I'll end up with a lovely mod, just a shame it wasn't like that OTB!
Merry Christmas Y'all !!

Merry Christmas darling, I hope its a good one ... Well, at least you had always planned to transplant a DNA 40 in it, so it should be beautiful when you are done.

Oh you too? I am so guilty
I got a Sxmini coming on Friday .. well here are some pics of the Robbot 1:1 Kayfun V4 that DHL FINALLY delivered, and it doesn't disappoint. Haven't built it yet, only took it apart and cleaned it. 
Hehe looking nice. My zna should finally be here Friday. I gave my iStick to a buddy. Gives me a reason to buy a new mini. I'll most likely be picking up a Sigelei mini and I still wanna grab a zero mod. I really need to stop buying new mods and atomizers... XD
I'll most likely be picking up a Sigelei mini and I still wanna grab a zero mod. I really need to stop buying new mods and atomizers... XDI been loving n enjoying my zna50 since I got it even though is ain't prefect in certain ways. So far I have been using it only with 18500 batt form without modification to the plastic thingy. There is some issue I want to check with u guys as I m a noob in using vv/vw devices, yesterday when I was using the zna when the battery level was at half level, it sort of delay n doesn't fire that well but today I change a fresh batt it could fire normally till quarter batt left at 3.7 volt. Is there any reason why is it so? Thanks in advance!!

Hun this is basically what I was speaking about above .. the lag in performance once the battery is less than 50%. Being that you are now stating the same this is clearly an issue with the chips design. So its not your imagination, I am experiencing this as well unfortunately.

Seriously?? What the hell? Did it ship? Tracking is saying that its still in NC or do you mean its still in the US warehouse?

Hello, newbie here with some questions :-/ just got a robbottech ZNA 50 today... Saw the volts jumping all over the place, and was wondering if I should worry about that? Could someone upload what volts they get at different wattage settings. Also - it didn't come with any manual... Is it just plug and play? Or are there different things that can be done with the menu? I bought a cloud chaser 18650 40 amp battery because that's ejat they recommended - could that be causing the volts to bounce around? It made a high pitch sound several times too so I took it apart and put it back together and the volts stopped bouncing around. But that sound is still there when I drop it down in watts. I'm using the Atlantis at .5 ohms.
Just got mine today. So far ohms read correct. Button is NOT clicky like my Cloupor DNA30 (Cana). I could hear those buttons clicking in the next room. Really nice button IMHO with no misfires. Up/down work well and actually seem oriented correctly (when looking at the display, upper button is up and lower is down wattage). Had the dirty film that others have commented on but no scratches or blems. Fit and finish is pretty nice for a clone. Has a lot of heft to it. Has the "click to wake" thing going on but no biggie because you have to make a deliberate effort when picking it up (feels like I'm picking up a Ruger P89 LOL). So when you see the display is off, click once and it's ready to fire before you touch it to your lips. I observe the "ramp up" when fired as well. It accepted a Sanyo 18500 1100mah flat top no problem. Will let you all know about the drop off if it occurs. Running an EHpro Kayfun @ .7 tiger coil and 15watts. Like Nikki, I don't crank to the max as it would probably put me on the floor. Unfortunately, I don't have an inline tank meter to check the output if I feel it waining, but I do have a multimeter to check the battery when it cuts out. Got a package from FT coming tomorrow (yea! only 15 days to AZ) and will spin up one of the Erlkonigins @ 1.3-1.4 to see if the on screen displays seem accurate. As a note- my $2 tracking option from Focal USA warehouse got me Priority Flat Rate Box ($5.95). Ordered on Tuesday night and got it today.
As Nikki stated, this does a "ramp up" (slightly more voltage than what is required for your wattage setting) for a couple seconds when fired to heat the coils. Maybe that is what you are seeing.
So it begins. The "boost" on this is garbage. a .7 @ 20 watts should be putting out 3.74V. According to the display we're at 2.4V and fluctuating lower. After firing it goes to maybe 3.1 then fluctuates downward. Battery gauge still shows 3/4 and multimeter shows 3.88V left. I believe these were 10A batts but can't confirm because I've had them for a while and stopped using 500's (so I've forgot and they were unmarked). This is on the aforementioned Sanyo 18500 1100mah (pink wrapped), (don't remember the amp output on these and they are unmarked). These batts were seldom used but performed better than AW's back when I was still doing mechs (Poldis primarily). Think this may be going back for a 30W.
Nikki, can you tell us does the 30W have the spring loaded 510 (a really nice touch IMO)?

So here's the fuzzy soft core porn (kinda like Penthouse vaseline lens to Hustler I can see what you ate comparo). i'm between jobs and usually get a nice cell phone included but have had to dig out an old LG with 2 megapixel:
Looks WAY better in person! I'm urby2112 from ECF and have had my share of Bugs, iHybies, Poldis, GG, etc. The body of this device is top notch, but the chip is looking, well questionable. Might try to hit the local vape shop for an output meter. Battery meter @ 2/3 now. To be continued.

Nikkita,Oh you too? I am so guilty
Did it come with the Svoe and P3 connectors?
And if I up the wattage to 40W, the output on the screen still shows 2.9V with 3/4 battery gauge showing. Definitely not vaping at 40W or like I said, I would be floored. Tastes the same as 10-15 watts. Multimeter shows 3.77V. My Prov mini does it's cutoff @ 3.4 so the batt gauge on this is not correct either. BTW mine is zen#1207 as well at power up (only for like a millisecond).
So Nikki, if I could convince Doris to let me keep this spring loaded 510 top cap would it work on the ZNA 30 version? My battery is still going but like I have posted the "boost" is def way off spec. I'm assuming the Cloupor V3 chip in the ZNA 30 is probably the same as the Cloupor V3 box mod (Cana mod from ele8vape) I sold to finance this ZNA (which was rock solid). LMK. This a bummer!
Yup, as all have stated, it's a mech mod after the battery gauge goes below 1/3. Mine went from 1/4 gauge to 1/2 gauge in 1 puff. Robbot really dropped the ball on this one. Should have bit the bullet on the machining loss problems and went with a good chip. They could have cornered the clone market on this device. Ugh.
Both the Robbot ZNA 30 and 50 are Z2 threaded so the tubes, top cap and bottom caps are swappable between each other as well as the authentic HoH ZNA/Zenesis parts. If you plan on ordering a new Robbot ZNA 30, I believe the new revisions have the same spring loaded top caps as the 50.
Hey ms, you ended up with the same probs as me right? Damn this is such a sexy slick paperweight!
The 50 I originally received was defective. Board would immediately begin to heat up so I sent it back. Still waiting on my replacement which should hopefully arrive today. Was supposed to be here yesterday.
My ZNA 30 is still running flawlessly tho. Gave it to my girl cause she wanted it.

My Robbot ZNA 30 is still running flawlessly. Very nice chipset. ONLY complaint I have/had with it is I think it stores button presses in memory. What I mean by this is you know when you press the fire button 5 times to turn it on/off? Well if you press it 3 times and stop, later I would only have to press it 2-3 time to turn it on/off because it stored those other presses in memory. It was weird.
My 30 accepted flattop 500s out of the box. Some peoples needed to remove a spacer. Seems its the same with the new 50. Some peoples work out of the box they are reporting. I needed to remove a spacer.

Remember that, not a biggie for me. The big downer on the 50 was as I was watching the output voltage and gauging my TH, I went to steamengine and checked the volts/watts and even w/out the inline meter, I was showing a low output voltage, 2.3V (was basically firing @ 7.35 watts) 1/2 battery gauge and it felt same, even for a low watt guy like me.
Sounds like I'll prob be throwing my dna40 into it, but I'll run it with Robbot chip for a few weeks to check it out.
Are your ohms by chance hoping all over the place? Wonder if that may be contributing to the issue. My defective one was jumping around until I tore it down and cleaned it all out with wet wipes. Spacer under the top cap was in their tight. Took a bit off effort getting it back in. Metal shavings galore were under there btw. Damn thing was filthy top to bottom.

No. First thing I do with all my mods is cleaning with isopropyl on q-tips. I commented about the machine oil but that was only on the body of the device (exterior). Took all the threaded stuff apart and was actually surprised that the cotton swabs came out pretty clean. A lot of my higher end mods (Chia, Polti, GoodGod) have came to me new with way more machining gunk. My first thing with any mod is the cleanup and potential Noalox treatment,
Ok after few days of using the zna50..: then using 18500 batts... The zna sometime refuse to fire or delay its firing once it drop to half batt. Sometimes it does fire normally at half batt without any problem..this is just getting damn frustrating in certain way. Had yet try it with 18650 batt.. Which I believe will be better. Currently using Lemo at 0.9ohms built.when is not giving me problems..it works really well with Lemo @20watts. Btw mine zna 50 doesn't come with the robbot tech sticker covering the chip. 
Only bounce I saw was the "ramp up" that Nikki spoke of and that was only during the top 1/3 of the battery. As it got below that level, I didn't even see the "ramp up". I'm not a chip guru but even to me this seems like junk! That Cloupor V3 was the bomb. Funny thing, it's sitting on my desk in a Priority Flat Rate Box waiting to ship. I sold it to finance this purchase only because I have always loved the ZNA form factor. I got bids so I can't keep it and it WILL sell. UGH.
