Mech Mod Harshness

[DPCardoza]

I recently received a ehpro overdose with a ehpro Tobh atty. I built dual coils using 26g kanthal. I don't have a ohm Meyer but according to my Provari it came in at 0.9 ohms. My juice is 11mg and oh my god I thought I was gonna die after one hit. Is this normal? Is it the nicotine or am I doing something wrong? I'm fairly new to vaping and very new to RDA'S. Help or advice would be appreciated.

Welcome to ECF, DP...

You built duals, in parallel... and the net resistance was 0.9Ω?

How many wraps, or... what was the gross length of wire?

See... if you built dual parallel coils from 26 gauge... they'd need to be around 18 wraps to have a net resistance of 0.9Ω - so something isn't right, or those are some very large diameter coils... or some very long legs.

Or... you built them in series, and they're around 5 wrap coils.

If you're coming from a glasso... then yes, an RDA will be quite a bit more potent.

Need more information on how you made your coils. What did you wrap them around (diameter)?

Yes, you need to drop your nicotine level at least one level with a rebuildable. Bigger coils and larger wick = more e-liquid consumed & more concentrated vapor = more nicotine per puff.

You may need to drill out the air holes in your RBA cap. Not enough air flow can cause a harsher hit.

Get yourself an oh meter or digital multi meter.
Your coils should be equal if in parallel.
You could cut down to a single coil and it won't be so overwhelming.

Be safe!

Nicotine is something to look into, there is a reason not many drip above 6mg.

Actually... I'm not sure I'd say "not many". Most of the folks I know locally and well, all I drip 12 to 18... including myself.

6 wraps. This was using my Provari though to test ohms. Unsure how accurate it is. Now that I have everything put together and the wick saturated it just read Lo. And yes I'm coming from a kanger aerotank.

Buy a meter. Buy a meter. Buy a meter.

Something is off. 6 wraps on a 2mm mandrel with 4mm legs (typical) would be 0.6Ω per coil, or 0.3Ω net resistance for parallel duals... and it definitely wouldn't fire on a Provari.

And what Rick said too. ;-)

I built it to look like this. Not sure what in parallel vs series means exactly.

I will, I will. I just forgot one when at my local shop today.

That is a set of parallel coils. The gross resistance of each coil combined actually reduces resistance to that of 1/2 the resistance of a single coil. So two 0.9Ω coils in parallel is actually 0.45Ω net resistance.

Coils in series or "end to end"... which isn't all that common, doubles the gross resistance of each coil.

And... if you're going to play with mechs... get a DMM, and click on my second sig line hyperlink.

Agreed. I'm an 18-24 mg vaper when using my MVP v2 or an ego twist (depending on the juice flavor). I recently went to also using RBA/RDA's on a mechanical mod, and had to reduce many of my juices to from 18-24 to 12mg, and a couple less aggressive 24mg juices down to 18mg. Only one flavor was I able to use the same 18mg nicotine level of 18mg. From my own experience I've found that since going to a Mech, the Menthol + Cinnamon flavors (I use fire &nice), and the candy/fruit flavors are especially harsh when keeping the same nic level. Not to contradict myself, but as I mentioned above the only flavor I was able to keep at the same level was, ironically the candy/fruit flavor of Strawberry Bubblegum. Hope you get things settled.

Thanks a bunch. Makes sense n now.

I'll get it down. Just need to do some more research and get a meter. It was a tobacco style and the throat hit was just insane. Hadn't coughed like that since I was 16 and trying the other stuff.

After reading through a few threads I think the rayon might be part of the problem too. Next build I might try some organic cotton
