5 hits per drip, normal?

Your wires are really all very inconsistent. You need to practice more and watch more tutorials. And how do you get 1.8ohms doing parallel dual coil? It is not possible at all with 28g wires. I believe you mean dual coil. Parallel dual coil is a completely different build.

You need to pack your coils tighter and you will be fine

I'm getting some really nice vape from this 26g twisted coil at 0.6ohms.

I would suggest you read up on power distribution. A simple would be that on dual parallel power is split into 2 whereas a single coil absorbs the full effect. Also as Voltage=Resistance*I(current), Power=I(current)*Voltage. Mainly we'll be using I=V/R and P=I*V for simplicity sake

Voltage remains the same on parallel whereas current is split.
The same is inverted when they are in series where voltage drops and current is same in series. (This applies mostly on dual battery mod where batteries are in series)

edit: Also to heat dual coils to the same heat as single coil should in theory use 2x as much power however a lot of other factors comes into play (personal preference etc)

edit edit: Also as to resistance, resistance in parallel is actually (sum of all resistance)/(number of resistance) aka average of sum of resistance (this is what years of engineering gave to me haha)

That is quite a chunk to digest now so I'll read it up when I'm fresh in the morning. Anyway thanks bro!

This is my single coil rda build, in case you need a reference. This is 28g, running 1.7 ohms I think.

But does your build glow like mad when dry fired?

I tried tweezing em together after firing em red hot but I'm still getting how spots all over and I've given up cos I'm running low on my wires so I'm back to dual coils 11 wraps giving me 0.8ohm.

Dual parallels are already giving me some issues and it isn't firing at hot as I expected to be. Like I mentioned, I built a single coil 1.1ohm and when fired its red hot that you can't really look at it directly as compared to my dual parallel which doesn't glow as red as the single.

Errrr sorry I meant 0.18ohm. So it's a dual coil with dual parallel coils on 28g.

Imma let it rest for now till my wires comes in and as of now this is my current build and it's working fine for me reading at 0.87ohm with 11 coils each.

Hi all, I've been vaping for a month or 2 now and I'm running a little boy RDA on a smok M80.

I seem to be only getting 5ish nice hits after every drip and I dont literally a drop and it's quite frustrating and I've been changing my coils to different wraps and diameters but 6 is the longest that I went.

Anybody able to advise me?
I'm on 0.6ohms dual coil on 40w.

TIA

By "drip" do you mean a single drop of juice, or soaking the wick?

I run around 20 watts and usually get about one big draw per droplet of juice I add.

I run an almost identical setup, 28 gauge kanthal 2.4 inner diameter 1.7 ohms.

Meant to quote Java, it's his build I was comparing to

Hey @GoBlue88, not sure if you could change those allen screws to philips, but if you notice my build, I raised the left lead on my coil to wrap around the top of the philips instead of inside the post. This raises the coil completely (if your RDA has sufficient height), allowing more air flow below the coil.

Gives me a much better vape! Not sure if you'll dig it.

after squeezing them give them a strum across with your screwdriver(magic!works by introducing micro spacing between coils) Also a rarely mentioned tip is to pull the leads as tight as possible into the screw holes then screw them down(remember to insert screwdriver into the coil to preserve shape). Dual coil needs nearly 2x of the power to glow similarly

And if all else fails, stick to single coil before you move on to dual-coils.

Cool! So how did you attach the leg?

I wrapped it around the screw and screwed it down! Simple but effective. Look at the space I have below the coil. Also the lead coming off the top helps support the coil and keep it straight and not saggy.

Very cool! Maybe especially important for me because I'm using a Sapor (top airflow). I see why you mentioned the screws now. I'll have to look into that.

just wanted to show off my dual nickel before changing them[emoji3]

Coming back to the OP's issue.

One more thing is to try out spaced coils. Sometimes when the coils are too jammed together, they overlap. Overlapping can cause hotspots because there isn't enough microspace.

Definitely soaking wet and not just a drop bro.

I've tried strumming the single coil setup but it's not any good. So you're saying that I should make the coil as close to the post as possible?

imma try 1 last time for the single coils with an evenly spread out coil. Anyway will running 40w on a single coil be too high?

 

[iSuck]

This is my woes now with a single coil even reduced it to 25w.
