Question about RDA No Vapor

[dirtybirdy]

I recently purchased a tobh atty clone (ephro) and panzer black hawk (acerig). I am new to building coils and such but I have watched tons of videos on YouTube about how to build coils.

So I purchased some 22g Kanthal A1 wire and just did a simple coil I think 5 loops around a 1/8 drill bit. I made two and stuck one on either side. I then shoved some cotton through the coil and left room under the coil so air could get under it.

When I hit it my vapor production is so poor. The guy on the video that did the exact same thing vapor production is huge. I get more vapor off my Vamo with Kanger Aero tank on there.

I just don't know how to fix it. My ohms is reading .31 so I figured that was pretty good. Any advice would be greatly appreciated.

You left out very important info. What battery are you using. Brand. Model. Amp limit?

What type of coils did you make? Open loop or comressed microcoil?

You've started out pretty daring building a dual coil at 0.31 ohms. Having the correct battery is extremely important at this resistance level.

So after we know what battery you're using, we can try to diagnose what your problem is.

Does your battery have a full charge.
Is your 510 making a good connection between the atty and device.

My battery is a Sony VTC4 2100mah 30AMP Battery

As far as the coil goes I went off of this tutorial 22 Gauge Macro Coil/Wire & Resistance - YouTube

I would be more than willing to build a higher ohms coil, I am just having problems on any coils I build producing barley any vaper.

My battery does have a full charge. The atty and the device seem to be making a good connection. When I test fire it, it produces a good amount of vapor but when I take a hit off of it does not. It also gets super hot within like 2 or 3 seconds of hitting it and it is very harsh. I don't know if that is just that device that I ordered or if they all do that.

Battery has enough amps. Good.

0.3 ohms will produce a pretty warm vape and could seem pretty harsh to some folks if not used to it.

22 gauge wire will take a good while to heat up, too, requiring longer pulses to produce good vapor.

My guess is if you are using the default air holes in the cap, you will need to increase their size to allow more air flow. Restricted air flow will cause a warmer vape and restrict vapor production. This is most likely your issue. You'll probably need to drill them out larger.

Thanks the thread was helpful. I had already ordered some new kanthal. I got 24, 28, and 30g on the way.

Thanks for the information. My air holes are very small.

Just out of curiosity if I used 28g wire and just made a single coil with 8 wraps I think that would put me closer to 1.2-1.4 ohms would that produce any more vapor than a vamo with a kanger aero tank?

Also since the ohms would be higher it would not be such a harsh hit correct?

Thanks

Can u post pics of your build please

A .31 coil should produce a good cloud I need to see your wicking cause that's 50% of coil building

Depends.

Generally speaking, higher ohms will provide a cooler vape, but often results in less vapor production. It's a catch 22.

I still believe your issue is the air flow, or lack of it. Stock air holes are almost always too small regardless of the ohm coils you can make. If you don't have access to a drill, see if you have a vape shop who does and is willing to drill them out.

Did you put the top cap on so that all of the air holes are open?? Seems like a dumb question, but the TOBH should be giving you a decent amount of air out of the box.

 

[halfempty]

Another dumb question, did you check to make sure that all the connections on the mod and atty are clean and tight? I've had brand new mods come with loose switch screws and machine oil on the threads.

 

[tayone415]

Have all 3 air holes exposed and directly in front of your coils and make sure your coils are the same level as your air holes. Could also be the type of juice your using if it's a 50/50 blend or something with higher PG, it could also be your drip tip if you have a narrow bore drip tip that's restricting airflow giving a tight draw and it could be your inhale/exhale technique. It could be that your wicking is not done right, maybe too much cotton, lumpy cotton or it's too tight in between the coils, or it could be your coils.

 

[stumpfreeman]

Your coils may be shorting out on the top cap. Try teasing them back a bit.

First off, are the blackhawk threads painted? If so then that is most likely ur problem , also tear down the mod and thourgly clean it.

 

[Asbestos4004]

Dual coils with .22 ga at 5 wraps apiece is more than likely going to be well below .3 ohms. I'd be careful.
Bad is right...if you're getting vapor without the top cap , then your issue is with airflow. As was already suggested, line up all 3 airholes directly in front of the coil. Make sure that little tab isn't blocking any of them.
Again, that build sounds closer to a .1 or so.

 

[Bunnykiller]

22 ga. duals at 5 wraps is going to be low.... like .18 ohms range 26 ga at 5 wraps on an 1/8 bit duals runs at .4 ohms
consider getting some 28 or 26 ga......
