Ideal Power for a RSST?

[TheOnyxEgg]

Just received a Pyrex RSST and built it up with a solid wick (400 Stainless Mesh) and a 2.0 Ohm coil. (30 gauge 4/3 wraps) I used an unoxidized piece of mesh and the pulse method to get everything heating evenly.

This is likely quite a bit higher resistance than I want, as on a Mech performance is pretty anemic (though it works pretty well on an MVP at around 4.8 volts).

Other pertinent information:
50/50 juice
stock air hole in top cap (pretty darn tight, going to drill out to 1/16 this weekend)

I love the flavor and smoothness of the vapor, and am thrilled that I got a coil and wick up and running on my first try (after some of the stories I've heard).

So now the meat of my question, what power level do you find works best for genesis atomizers (more specifically the RSST)? As I mentioned above, I'm going to be drilling out the air hole this weekend and will likely be taking a stab at wrapping a lower resistance coil this weekend.

Also, is it worth trying to reuse the wick and wrap a new coil on it? I have more mesh and could roll a new one, but if this one is wicking well...

With that same build, mine can last a month or more with cleaning.

In regards to ideal power...that's all preference. If you're content with it so be it, but rebuildables can handle more wattage than you currently are using. If the flavor and vapor production satisfies you, then stick with it.

The ideal power for the RSST is the one you like most. No one can answer this question for you. All they can do is tell you what they like. To assume you would like the same as them would be unfairly presumptuous. Try it at different power settings and decide for yourself. Go by your watts (power). Not the volts.

Next time, try a kayfun. Gennies flooded the used market after the Kayfuns were released. With good reason.

Good luck!

Thanks for the input thus far.

I realize that this is a personal preference thing, hence the "What power level do you find works best" question. I'm looking to get some input on what others have found to be good power levels for this atomizer with this setup.

I guess I wasn't absolutely clear in the initial post, but I'd prefer to use this on a mech and not on a regulated device and had mentioned that the performance was pretty poor at this resistance on those types of devices. I like the quality of the vapor with my current build at ~4.8v (on a regulated device), but find the quantity a bit lacking. (It's considerably less than I was getting from a cartotank w/ LR cartos). I've heard that getting more airflow will help with this, which is why I'll try drilling this weekend. The stock draw is very tight as well compared to what I'm used to (reminds me of the iClear 16s that I used to use).

Thank you for the suggestion on the Kayfuns as well (seems you can't make a post in this forum these days without everyone saying "KAYFUN!!!"), I'd looked at those before picking up the RSST but decided that I wanted to try something with mesh. I'm sure I'll pick up a device from that family at some point in the future but am more interested in working with what I have at the moment. To be honest, my next purchase will likely be a dripper of some sort... but that's for another discussion.

If you're going to use it on a mechanical, then build around 0.8 - 1.0 ohms (especially you have one coil) or even lower if you don't like it. Currently you're vaping at around 11watts. Once you use that mechanical mod and vape around a 0.8-1.0 ohm build, you will be vaping at about 17.5 -22 watts.

Keep in mind... Kayfuns are for flavor with ok vapor, gennies (rsst) are for flavor and great vapor.

Thanks for the advice!

I'll give a ~1 ohm coil a try this weekend when I rebuild it. I just tried the current build at 5v which should be around 12 watts (not sure why I stopped at 4.8 before) and it was even better, so I look forward to seeing what it will be like at a bit higher wattage as well.

Do you find these work better with more wraps of a heavier gauge or fewer of a lighter?

I had RSST for almost a year. Somewhere between 0.9 and 1.2 Ohm was sweet spot for me on mech. For me personaly, RSST was working best with 4 wraps of 0.28 kanthal, best flavour, not to hot vape. Any lower than 0.9 and vapor would be too hot for my personal favor. What u need to do is to drill that hole for air at about 1.3- 1.4 mm, anything wider than that and u will loose some of the flavour, any tighter and u loose amount of vapour. At least that is what worked for me. RSST is a briliant atomizer for those who are entering genesis world, but trust me, there are a way lot better things out there from RSST. Silver dog is at least for me absolute leader, or if u like smaller things, silver fox, The fox is running at 1.4ohm and i get more flavour and vapour than with kayfun with 1.2ohm...

Congrats on getting a gennie up and running at all. Kayfuns may be nice, but once you're able to consistently build gennies, there's not a whole lot a Kayfun can offer, IMHO. I dare say most of those who sold off gennies to buy Kayfuns did so for other reasons than vape quality. I think Kayfuns are a royal PITA on many levels and have never provided me with a vape even close to (almost) any gennie.

The mesh acts more as a heat sink than the fibrous wicks, so your assumption is right; you probably want a bit lower resistance. Something in the 0.7 - 1.3 ohm range should work nicely, varying with personal preferences.

I find thicker wire easier to set up. Lower resistance wire makes it (initially) less likely for the current to jump to your wicks as current follows the path of least resistance. Also, 30 awg+ has a tendency to snap easier when pulsing / sorting out hot spots. But, as you've found out, it certainly can be done.

In the spirit of "more cooks - more mess", fewer wraps are easier to work with than the opposite. I aim for 4 wraps, max 5 - and rather change wire thickness for different resistance. 28 awg for around 0.8 ohms, 30 awg for about 1.2 ohms. Both provide a satisfying vape to me. I do favor the 0.8 ohm setups tho. 4 wraps of 28 awg should get you there. Too many wraps of thicker wire will just waste a lot of energy to heating your coils rather than liquid. I want good wicking and a rapidly heating coil as to boil liquids at the surface of the wick - your main heat sink being the vaporization of liquids; not slowly heating the wick itself.

That being said - sounds to me like you got this pretty much sorted.

Thank you both for your input and advice, this is exactly what I was looking for. I could have just started experimenting to find what works best, but it's helpful to have others preferences as a starting point.

Just picked up a 1/16" cobalt bit, local home despot didn't have anything smaller in a quality bit. Looking forward to tearing it down and trying a new setup this weekend.

In case someone is listening. Here's a couple of builds. Both work pretty well. Subjective: simple coil produces more vapor, parallel - better taste. Not scientific, since different wick material, resistance, etc. RSST coil experimenting - Imgur

RSST is a nice genesis to get started, my first genesis was a rsst and now i cant vape anything but gennies, the power will depend of what mod are you using if youre going to use a mech my sweet spot used to be .6 - .8 ohm on a regulated device at 1.6-1.8 ohms at 12watts

Oy that's a bit unusual I think. Not saying it's wrong lol. Just wondering specifics. Is that on mesh? And what wire gauge? How does the vapor and flavor compare to your previous preference - 0.6-0.8 ohms on a mech? That's roughly what I vape all day every day.

whats unusual ?
yes is on mesh iike 400 or 500 fat wick, using 28ga kanthal yes .6 - .8 ohms on a mech.

there is an important thing, once you learn how to roll the perfect wick with mesh and how to coil it without hot legs or hot spots, the flavor and vapor is exactly what i like.

Was just curious about the setup you use for regulated mods and gennies. 1.6-1.8 ohms at 12 watts sounded... (I realize it was the wrong word now) unusual. Probably should have used interesting instead. Sounds like it would perform wildly different from your mech setups... so I was just wondering if you had some neat trick to making gennies work at such (for gennies) "high" resistance and "low" power. If you used thinner wires or had come up with something otherwise clever

This sounds what I tried before with epic fail of "perfect" wick. The juice didn't reach the top. Could you at least give some hint of direction here? Do you make a wide straw, tight spiral, loose spiral, tight straw? What's the size relative to the deck hole? Picture, maybe? Sorry to bombard with questions, but I'm kind of stuck with mesh here. Thanks.

i have too much time without using resistance over 1.0 ohm my all adv build is a prometheus dual coil at .6 at 19watts on my zna, clt dripper dual parallel coil at .25 ohm zen dxc-650 copper, zenesis .7 ohm vaping at 20watts ZNA all with mesh except the dripper, 500 mesh works fine for me, for thin ejuice i like a fat wick for thick ejuice i use a double straw wick, and i try to stay away from wire higher than 30, is a PITA to work with thin wire.
