Rebuildable Advice

I got my first Derringer today. Wanted to try it immediately although I bought it with the DAY AFTER (May 2106) in mind... but you know how it goes, you get a new toy and you want to try it out.

I'm really not into very low ohms so first I went for a single coil - 26 AWG Kanthal, 9 wraps for around 1.3 ohms. But I didn't like the way that could be wicked in an rda. So then I put in two 28 guage coils which I had previously coiled for my other atties. Together they gave me .8 ohms which is sort of ok. But I still am not quite happy with the wicking. These coils are 2mm internal diameter and there's not a lot of cotton you can put in there. The taste is good but my wicking is nowhere as fat as I see in some pics online.

Any advice?  

I bought a Kanger Subtank and Atlantis V2, but sold them because they just weren't wicking my 100% VG liquid (Velvet Cloud & Gypsy eJuice) well at all. I tried using the atlantis with the .3 ohm coil installed at 70-80W, which was the stated operating range, and found it to be EXTREMELY hot. So hot that the tank quickly heated up to the point of almost burning my lips. The Kanger just burned the wick up at 20W+ with the .5 ohm coil, despite letting it sit filled for a few minutes and priming.

I am very interested in picking up a Royal Hunter, although I've no idea what pre-made coils (i dont want to make my own coils, just dont have the knowledge or time to learn how) and battery to get. VaporDNA sells UD pre-made coils in various resistances, but figuring out what resistance to use, and thus what wattage battery to get is where I am stuck. Not sure if it'd be better to run at lower ohms / higher wattages, or higher ohms / lower wattages. I'm not sure if it's possible to get massive clouds, but a cooler vape at the same time, but that's my aim.  

Hey guys if i was to use the cloupor mini 30 watt regulated device with an efest imr 18650 35a
battery am i safe? will the cloupor see any overheating of the battery if it were to happen? or will it see if the ohms are too low? the lowest ohms i plan on using is .8 possibly .6 but i just wanted to know how safe is this device? also i am aware of the recall on this i will be doing the "too hot" test on it. thanks for your replys!  

Hi guys,

Is it really normal for an atomizer to get hot especially when using dual coils?
I just created a dual coil a couple of minutes ago using 24 gauge kanthal wire, 10 wraps each on a 2.4mm precision screw driver. My meter shows that the resistance is at 0.4 ohms, being curious and all since this is the first time that I made a dual coil, i decided to test it out.
Got some good flavor and vapor, though the vapor is warmer than I would want it to be ( I prefer cold vapor)

After taking a couple of 5 secs drag, I notice that my atomizer became hot, not warm, but hot. Is this something that I should be concerned about? I am doing something wrong or have I done something wrong when creating my coils?
Please help.

Here are some pictures of my device and atomizer. ( Philbox wood mod running on 2 pcs of AWT 18650 2600mah battery, my atty is Haze by vapehead origins)


 

Okay so not sure if this is the right section or not but its the only relevant place I could find. .

My first build was okay coils turned out fine but the wicking and position of the coils where terrible. So I decided to have another go.

Opinions appreciated.

Using smok xpro m80
Plume veil v1.5 clone
26gauge kanthal
Wrapped around a 2mil precision screwdriver.
8 or 9 wraps can't remember.
And reading at .46 ohms

P.s don't know why the coils look like there glowing purple but I promise their not haha.
 

I purchased a Vaporesso Swag II.
It comes with two coils. One of them is a
0.15ohm GT4 Meshed Coil - rated for 50-75W, best 60-70W I liked how it tastes.

The Swag uses one battery only.
Is it safe to use Samsung 30Q 15A batteries and run the Swag at 65W?
If not, what battery would your recommend in order to use it safely at that wattage?

I’m asking because I have always considered the “rule”: maximum W = 3XA  

Due to a recent rash of vapers using mech mods without proper knowledge. here is a simple test for vapers who want to use unregulated devices, if you can confidently answer these questions, you just may be ready to take the plunge to a mech or unregulated box mod. If you cannot answer all of the questions, don't be discouraged, use the test as a base for the knowledge you may need to acquire.


1. Define ohms law using a short paragraph, and show the equation below.

2. Define watts law using a short paragraph, and show the equation below

3. Draw a simple open circuit.

4. Draw a simple closed circuit

5. Find the resistance of a circuit running at 3.9 volts with a 20 amp current

6. Find the voltage of a circuit running at .54 ohms with a 5 amp current.

7. Find the wattage of a 4.1 volt circuit at 2.3 ohms

8. You are wrapping a dual coil set up, while pinching your coil with metal tweezers you accidentally press the fire button,
the leg of the coil you are wrapping fires bright and then disintegrates, why has this happened?

9. Your mechanical mod is getting extremely hot, is making odd noises, and has an odd smell, what is happening
and what is the procedure in this situation?

10. What is the lowest safe resistance of a 4.2v lithium ion battery rated at 20 amps?

11. You have been using a battery for several hours now, and have noticed a sharp decline in vapor production,
why is this happening?

12. You wrap a coil that reads .42 ohms on your multimeter, what important factor should be remembered while using this coil?

13. You are using 2 stacked 18350 lithium ion batteries in your mod, what kind of circuit is this? what changes because of this?
what does not change?  

I just Started rebuilding my kanger dual coils and im having a issue , seems like when i build them and check my ohms on my meter they are right where i want them but when i put them in my tank and fire them up the ohms fluxuate like crazy from low to high ohms, any idea why it happens ? It occurs even when i build single coils. Anyway to fix this? Thanks  

My MVP 20 watt recently started to get a little wonky on me. I use 1.5 ohm coils in an aerotank but for some reason the MVP is readin it as 4.9 and sometimes even higher. Of course its not hitting right either. I know its not the coils because if i put that same tank on my MVP 2.0 it reads correctly. The MVP 20w doesn't do this all the time but today its been doing it all day. It won;t go below 5 ohms and sometimes its even higher. Is this thing shot?  

Hello guys,
I recently purchased a single coil RTA, my first rebuildable experience. I love it!! .
I saw at the shop a double coil RTA and a Double coil RDA, was planning on buying one of them until I thought I only have a 100W mod. Do you guys think it is enough? Are there some specific ohms coils that could make it work etc? Or is a 100W enough? I am new to this so calculating ohms law and all the other stuff I will learn, I just need a answer from the double coilers if you guys use higher wattage mods or not.
Thank you in advance!
