Cooler vape from RBA/RDA

[onem0hit]

I feel like everyone here prefers the TH and vapor temperature from top coil rba and rda, along with sub-ohm, etc.

I was wondering if there are any ways to achieve a cooler vapor from an RBA such as a RSST or AGA-T, which I find to be a little too harsh even at 1.8ohm on a mech mod. Also looking for advice to cooler vapor from a rda like a A7 or IGO-S. I have used SS wicks in the RBAs and cotton and XC-116 wrapped SS in the RDAs.

I have tried to enjoy the increased flavor but the harshness of the vapor production is preventing that. I have been using mostly 50/50 mixes, if that is relevant.

Bump, also interested

I enjoy the cooler vape from the protanks, looking to replicate something similar from a RBA

I hear RBA's like the Ithaka produce a cooler vape. I like warm vapes myself so I haven't tried one.

Longer driptip, different driptip materials (glass, etc). Aligning the airhole to the wick/coil rounds out the harshness for me. If not, maybe just gotta go up in resistance (it is a rebuildable afterall).

i hate a mouth burner too.
i've been using these and they work great.

I concur with SteamDaddy and Aoi. I prefer a cooler vape, also.

I wrap a 2.o ohm coil for my AGA T2, and use it on either my Silver Bullet or two Provari's. I also use one of the long drip tips like Steamdaddy recommends - I got mine (colored) from My Freedom Smokes. The blue-grey one nearly matches the blue satin color of my Provari. 510 Long Skinny Drip Tip - Aluminum - MyFreedomSmokes.com

this is the cheapest place i've found them so far.
Stainless Steel Drip Tips

i've been playing with making my own from aluminum.
2"-2 1/2" is where it's at.
anything any longer just doesn't work

I've found thicker wire, with more coils produces a ton of vaper, cooler.

How much thicker would you recommend to get something around 1.8-2.0 ohms. I have been using 30ga but have not tried anything bigger.

And thank you to everyone else. I think trying a longer drip tip may be the answer. I drilled out a second hole in my IGO-S which helped a lot. I put a 1/16th hole opposite of the small hole. I may drill out the RSST and see if that helps.

Anyone have advice as to whether to make a second hole in the RSST or just drill out the existing hole? I don't want to sacrifice more flavor than is necessary...

Yes, a larger air hole will help, but thicker wire with more wraps is the answer you're looking for.

Try 28awg with a 6/7 wrap or there-abouts. Widely spaced coils.

Thanks for the help. 28awg A1 wire has been ordered.

1.8 - 2.0 yeah... 30 is about as thick as you can go... 28 at that resistance would need to be a wire about 4" long... that's a lot of coils to try and cram into any atty... no matter how you wrap it.

Even with 30 you need about 2.5 - 3"

Really this thicker wire only comes into play with Super Low resistance... for instance to build my favorite resistance coil, I use just under 2"(0.9 total resistance) of 28 gauge wire, coil it up in whatever way makes me happy at the moment... big wraps, evenly spaced around a huge wick... micro coils actually touching around a thinner wick... whatever. Bigger, evenly spaced coils tends to run cooler in my expereince

Then I put it in the atty... the wire lost to the screws cuts the resistance a bit... generally I land at .8 or .85

Don't base your resistance off the #of wraps... it can vary greatly due to the size of the wick... measure your wire and calculate the resistance based on that, then wrap your coil using a known restance:

28 awg - 0.45 Ω/in
30 awg - 0.70 Ω/in
32 awg - 1.20 Ω/in

There Numbers are Approximate... but good enough to figure it out.

I would never add a 2nd hole, unless I had a 2nd coil.

You want more air flow directly aimed at the coil... not coming in from somewhere else.

For instance, I'm running single coils in my IGO-L and I drilled out the existing hole.
I would assume that adding one on the other side without a coil there, would be similar to having the existing hole drilled out, but lined up incorrectly.

I kind of ignored his requested resistance and just told him what would provide a cooler vape.

Oh yeah, I totally get what you were doing... and you fairly well described my coil...

BUT, imagine if he uses a triple 3mm wick, with 7 wraps.. that things is gonna be massive... and totally different than a micro coiled 7 wraps.

I think the biggest issue here is that he's aiming for 2.0 on a mech mod and expecting it to be a nice vape...

0.8-1.0 is probably what he really wants... and just doesn't know it yet.

I plan on doing a few rebuilds of my IGO-S and RSST tonight to see if I can find a better coil. I tried 1.2ohm on an A7 mini and 1.1-1.2 or so on a AGA-T and both were a little intense. I think some more experimentation might be necessary. I was also still fresh off the analogs when I tried those combinations so maybe that had something to do with the coughing fits that followed...

 

[The Yeti]

I'm vaping a 30awg 1.0 ohm coil on my RSST right now - when the bat was fresh, it was a little intense. But, as the battery settles down to under 4 volts, I find the vape quite cool and very enjoyable.

That being said, I can and do enjoy hotter vapes - try the same coil as above on an Igo-L...that's quite a warm (even hot) vape.

I like 'em both!
