Need Help Please

So I have a Vaporshark Rdna 30 with a Kayfun 3.1 , I have been trying to research and have read many web pages and posts here on this forum
But I am still confused as to what the recommended ohms for the coils should be and at what approx wattage
It feels like it's all over the place from sub ohm all the way to over 2 ohm coils it seems to me that's a very wide gap and also the wattage to vape a certain ohm coil without worrying about battery issues or burnt eliquid
So could anyone please reply with info on what would be good or any info they have about ohm and wattage ranges for the vaposhark and the kayfun also if there certain ranges I should follow
I am using 28 g kanthan with Cotten wicks
Thank you very much

That's because it's a really versatile setup. People run them all the way from super sub ohm coils to over 2 and anywhere from 6 to 30 or 40 watts based on their taste. Most generally fall in the middles - around 1.2-1.8 ohms and somewhere in the 8-15 watt range.

So to answer your question, the best place to start is to ask you a few. What mod and topper were you using before this? What do you like about that one and what would you change?

The previous poster answered your question well.

I will add the Power Law to give you a good idea where to set your power (watts). From there you can dial it in to suit your taste and juice.

P = voltage squared ÷ R

Voltage will always be 4.2 so voltage squared is 4.2 squared, which is 17.64.

An example using a 1.5 ohm coil:
P = 17.64 ÷ 1.5 = 11.76 so try 11.7 or 11.8W as your mod setting. You may find you like it a little higher or lower than that, but it gives you a good starting point.

Short answer:

Start with a 1.5 Ohm coil (see above). With 28 ga, I'm thinking 11 wraps (ish) on a 5/64" (about 2 mm) drill bit - common stuff. Master builders please correct this if necessary.

While you are enjoying the simple pleasure of a simple coil that will simply work, dive into the coil build subforum and research, research, research...

A Kayfun was my first RTA and is still one of my favorites, easy/quick to build, rugged, reliable and produces good flavor. What ohm/wattage to use is dependent on personal taste preference, what works well for one may taste terrible to another. You will have to experiment with various combinations until you find your "sweet spot".

On a single coil RTA like the Kayfun I build between 0.8 - 1 ohm and run it between 18 - 25 watts depending on the resistance. 25 watts for a 0.8 ohm coil and 18 watts for a 1 ohm. I use 26ga Kanthal for coils in that resistance range. I only buy/use Samsung 20amp 2500maH batteries ($6 ea), so the discharge rate isn't a concern with any of my builds not even the 0.4 - 0.6 ohm (35 - 50 watts), dual coil RDA setups I occasionally enjoy.

One more quick question
Is a 1 o coil better than say 1.5

None of them are better or worse, they're just different, and you should try both to see what you like. Different resistances, wire guages, coil sizes, height over the airflow, and a million other details will make your vapor hotter or colder, give you more or less throat hit, change the amount of vapor you get, and change the way the juice tastes.

The best thing to do is start in the middle (like 1.5 ohms at 12-15 watts) and see how you like it. Then turn the wattage up or down a little and see if that's better or worse. On your next coil, try to change one thing about it (try a different drill bit or fewer wraps or something else). See how that little change affects the vape and decide which you like better. Then change something else and see how that works. Play with it, have fun experimenting, and you'll find your perfect settings.

The thing that makes your setup so great isn't that it's one size fits all. The big reason it's awesome is that you can control it and adjust it to vape exactly how you want it to, which is probably different from what I like. You have so much more control over every aspect of your vaping experience with something like this. You can try anything from .5 ohms to 2.5 ohms and from 5 watts to 30 watts they they'll all work (although you have to wick it really well to get 30 watts out of it) and they're all different. There's no right or wrong, there's just what YOU end up liking the best.

Does that make sense?

I did most of the math for you . All you have to do is take 17.64 and divide by your coil resistance. If you don't have a calculator you can get one on google. Put 17.64 first into the calculator, then the ÷ key then your coil and hit the = key. I bet you can do that

Agree 100%, very articulate, well put.
