question about the Aqua

[AndriaD]

I've been looking around at all the different kinds of rebuildables, and I've determined that I definitely want an RBA tank, and one that can use silica or cotton wick rather than the mesh, or even allows both, but that still leaves quite a few. I've been looking at the Aqua RBAs, and it really looks like what I'm after, since I far prefer bottom coils; however I notice that it's setup to use dual coils, and I don't care too much for those, so I'm wondering, could a single coil be used instead? Also, is there a particular clone maker who does it better? I've seen both EHPro and HCigar versions of it, and I know they're both fairly decent brands, so I'm wondering which of them makes the better Aqua (clone)?

Thx

I have heard of some doing just one coil in the aqua which requires you to plug up some things and heard it does work good but imo if your not into duals maybe think of the kayfun or Russian. when plugging up airholes or juice channels in an atty that's not meant to may lead into issues but I guess if your just getting a cheap clone maybe its not that big of an deal if things don't work out. I own a real aqua so I cant comment on the different clones that are offered. good luck

I wouldn't bother to purchase an Aqua unless you intend to dual coil it. Otherwise, you're better off purchasing a Kayfun style intended for single coil and avoiding some of the Aqua's shortcomings, such as it's relatively small capacity, and occasionally messy fill, both of which are offset by it's awesome performance when properly dual coiled.

No reason not to dual coil it really. If you can single coil it, then you can dual coil it. Simply build the coils to your preference.

 

[AndriaD]

Hmm... but isn't there some weird backward math of some kind, about the ohms, with a dual coil? Please don't give me equations; I'm a total math ....... I've learned to rebuild the T3S and protank coils, I use 32ga, 7 wraps, and end up with 2.6-2.7 ohms, which is just right, won't drain the battery too fast. I would have no idea what to do with a dual coil thingie, and after my awful experience with the Nautilus, I really don't think I like them.

The Kayfun is good, but I can't seem to find one of the older ones without the airflow control. Again, on the Nautilus, I found that feature maddening; either it's wide open and you don't get a burnt taste, but you can't really even tell you've inhaled anything either, or you start closing it off, get decent hits but then start getting a burnt taste.

Also, I'm looking for an RBA tank with a brushed stainless finish. The kayfun appears to be either shiny as a mirror, or very dull, but neither finish is right for the Sigelie, which is brushed stainless. It's not mirror chrome, but it does have a sheen to it.

Dual coils are fairly simply to figure resistance.

In a dual coil arrangement such as the Aqua, the total resistance will be 1/2 of the resistance of your lowest resistance coil.

So if you wanted to build the Aqua for a total resitance of say 1Ω, you will need to build two coils, each having a resistance of 2Ω.

(1/2 of 2 is 1 )

Either way, always test the resistance of your build before firing it.

My ehpro Kayfun lite plus is brushed. It's also awesome. Adjustable airflow is COMPLETELY different than a Nautilus. You won't get many dry hits with a Kayfun, if any.

Yeah I'm planning to get one of those Omnitesters before I get an RBA. I've been using the built-in resistance checker in the vv3 and the Sigelei so far, but they vary by .1 ohm, everytime, so I'm not sure how much I trust either one.

Since I want high resistance, I'd have to build whopper coils with a dual. Think I'll pass on that; dual just isn't my thing at all.

Guess I'll go back to looking for a brushed Kayfun, or some other. I also need to find a Kayfun with which I can use any drip tip I want, because I despise metal driptips.

The Aqua shines it's best at lower resistances. My current build is running at .5Ω

Using something like a VV, you'd have to build it fairly high resistance, and I suspect you'd be unimpressed with the result.

However, a single coil Kayfun/Rocket would work well. I run a Rocket (kayfun style atomizer) on my MVP, single coil at 2.2Ω at 11 watts. Still a very satisfying vape, and much more so then a Protank/iClear ,etc, etc.....

I have an rsst have been building on it everyday. My best vape is a steel rope with a small mesh wrap where the coil is. Wicks great, no neec to tilt, and it should last a loooong time. Its firing right at .7 which is my sweet spot.

 

[EDO]

Check out the Taifun GT clone....the one from FT with all the accessories is great and dirt cheap.

 

[AndriaD]

I really don't want one that has to have a steel mesh wick. My only experience with those is not good -- someone PIF'ed me a couple of the cheap 510 drippers, which appear to have those steel mesh wicks, and everytime I try to use them, the first two hits are always "hot metal," and that is just horrible; I've also heard that RSSTs have a lot of issues that sound like I'm much better off avoiding. So no steel mesh; right now I prefer silica wicks in the coil, though once I can build a coil that doesn't require a magnifying glass to count the wraps on and is easier to get a wick thru, I'll probably go with cotton in the wick, as I now often use cotton for the flavor wick. But that's a maybe; I get that burnt taste from cotton a LOT more than I get it from silica.

And I will only buy stuff from the other side of the planet if it's stuff that I don't care when I get it, which is not most of what I buy; mostly I prefer to hunt up good sale prices here on this side of the planet that don't have to go thru customs, so I can get it within a week.

I'm going to be trying to build coils that will be around 2.5Ω, to save battery life, and also because I've found that low resistance atomizers tend to be very hot, and can easily burn my lips if I'm not VERY careful. Right now with my T3S's, I'm doing 7 wraps of 32ga, which gives a solid 2.6-2.7, and those are perfect. I might do 6 wraps for a kayfun, which would still give me about 2.3-2.4, and that would be acceptable, but, the main reason I wanted a removable-battery mod that takes 18650s was so I'd have long battery life for day-trips to my folks' house, so to take full advantage of the long battery life and really maximize it, I need to have coils that won't waste it on a hot vape that I won't like anyway. I'm not a cloud chaser, I'm a battery miser. Actually I'm an everything-miser, because to me the purpose of coil building is to save money buying replacements all the time, but now that I know how to do it, I'd like to get a real rebuildable atty, because I hear that they do give the best vape. But from everything I've learned over the last couple weeks, higher resistance means less amp drain, and therefore longer battery life.

The Aqua is a native dual sub ohm monster. Been running mine with a 0.3 ohm build for months now. A really excellent rba, with all the features of the Aqua, and only a tad more expensive is the Rose V2 rba. Can use it in either single or dual, sub ohm or standard ohm, and is one of the most exquisite rba's that ever came down the Vape trail. Missed out when the first version came out, but not this time!! lol.

If searching for tube mechanical mod, you might also consider using a kick module which will not only give you some adjustability for wattage and short circuit protection, but also extend the useful charge of the battery.

A Nemesis clone with a kick is a great combo....and also looks perfect with a polished/brushed kayfun.

I might get a mechanical one day, but for the moment I'm neither brave enough nor knowledgable enough about electrical minutiae; I just got a Sigelei Zmax v3 flat-top, and I'm finding with these smaller coiled clearos, I get a lot of burnt taste, so I really need something that can handle the kind of power an 18650 puts out, as opposed to the integrated batteries of eGo styles, even the vv3's I love so much. the T3S's work great on those, but I think the bigger mod/battery is a lot more power than those small tanks and coils were ever intended for.

I'll keep looking at the Kayfuns; I know that I can't afford anything really expensive, so it has to be a clone, but I do want quality as opposed to the cheapest possible price; which is better, EHPro, Hcigar (I think they make a Kayfun? not sure), or Tobeco? The Tobeco prices seem a bit lower, but maybe you get what you pay for. I've heard really good things about EHPro.

no doubt forget about the aqua. I have a bunch of kayfuns and all are not shiney at all, I would consider them brushed finish. yes the higher the resistance usually equates to longer batt life but not as much as you would think in a vv device because of the circuitry. if you do get a kayfun I can tell you they work better with micro coils and cotton and if you decide to go that route you need to forget the 32g wire. in a micro coil wick coverage is very important, if you only did a coil with 6 wraps of 32g wire the vape wouldn't be so good. now if you are going to use a silica wick with separated wraps then maybe the 32g would be ok. for the kayfun wire gauges of 28 & 30 are good with resistances between 1.5 to 2.0ish with a coil diameter of 5/64ish. with those parameters you can easily get a full day of vaping.

Well, tonight I finally solved 99.99% of the burnt taste problem -- in the kayfun vs kayfun lite+ thread, someone asked me if I was sure I was in RMS rather than Mean mode -- I wasn't, so I checked, and discovered the #$%&% factory default was Mean! @#$%&!!!!

So, with the T3S's at least, the burnt taste seems to be gone even if I go up to 8w; haven't tried higher, because I didn't really need to, 8w on this seems like 9w from the vv3's, so I'm happy with it. Still some kind of burnt-taste issue with the protank coil in my Hypertank2, but those coils just aren't as good, for some reason.

I really would not be happy at all with an atomizer running at only 2Ω; hot hot hot, hot enough to burn my lips. I'd want 2.3-2.4 Ω at the very least, to bring it to a temp I could deal with. And I'm not sure I could even make a micro coil; my 7 wrap regular coils are quite compact, but the wraps don't touch, in fact I thought it was bad if they touched, that it would make a short or something. I'm a total novice with things electrical, it could be quantum theory for all I know about it. I'm using this "Steam Engine" calculator to know how many wraps for the resistance I want, given the size of wire and inner diameter, but the math behind it? FUHGEDDABOUTIT! I'm a COMPLETE math ......, and at the age of 52, I really don't think that's going to change, in this life.

And when I do finally start making coils for a "real" rebuildable, I'm inclined to use 7/64 rather than 5/64, to make the wick-threading easier. I have a terrible time trying to get a 2mm piece of silica into these 5/64 coils, so I'd really like something a bit easier to deal with, maybe something I could *see* a little better!

But I think it's true that I should forget about the Aqua, since it really needs dual coils. I'll keep looking around for a kayfun that's not polished, is a decent price, and has a driptip adapter -- the last is a deal breaker; if I can't use something other than a metal drip tip, I don't want it. I use only one metal drip tip, a gunmetal Ming I got to go on my Mini PT II, since the metals on that tank are schizo, with both gunmetal and chrome, and the only reason I put up with it on that is that I use a cinnamon redhot juice in that, and if it can destroy plastic tanks, it probably wouldn't be too kind to plastic drip tips either, and the glass tip I have is too slender for that aperture. But I put that Ming in the crook of my arm for 10 seconds before I try vaping on it, it's so cold on my lips in the morning when I'm vaping that apple-cinnamon stuff.

I definitely understand the heat issue, though I think a lot of that has to do with the design of the atomizer and drip tip, as opposed to just coil resistance. I run my russian 91% at a very conservative .9 ohms, usually at 15-16 watts, and I never have any heat issues.

Wow, some serious wattage there. It must be true that these things are just completely different from the tiny coils I'm accustomed to, in every possible way.

I have some questions about the various Kayfun clones, but I think I'm going to take them to the Kayfun vs kayfun lite+ thread, since they really don't pertain to the Aqua which is the title of this thread. Guess I knew all I needed to know about the Aqua, when I learned that it's not really feasible to use a single coil with it. Because these rebuildables *are* so very different from the tiny coils/tanks I'm used to, it may be that duals wouldn't bother me in that kind of device, but with all the math problems, having to divide or multiply or whatever it is you have to do to get the *actual* resistance when you have duals, I think this math ...... is much better off to stay with single coils.

Thx!

FWIW, I run my Aqua with a single coil, works well for me. I plug the unused air hole, on the deck, with a toothpick and pack the juice channels on that side with cotton real tight so it don't leak.
