rda noob with some questions.

[bencooper74]

OK so I've been vaping for about a year now. I have a ego 900mah and a lavatube v.2. I only drip and I want to start using rebuildables.

here's a few questions I have that some of you rda veterans hopefully can answer for me.

1. can I or should I sub-ohm on my lavatube? I think there is a 2.5 amp limit on my device.

2. can you recommend an inexpensive rda that would be good for a newbie. I would preferably like something that comes with a factory coil installed so I can see what it supposed to vape like before messing around with my own builds. I was looking at the pheonix v4 mini.

3. what gauge wire should I be using and how many wraps? maybe there's a good thread or chart someone can refer me too that shows what gauge/wrap to use for specific ohm's.

any tips or info would be appreciated....thanks!

Once you enter this world, you won't go back. I just got an IGO-L for 13 bucks yesterday. A few youtube videos and questions later, I have built 4 coils. I started with 34 ga, but the consensus is 30-32. I don't plan on going sub-ohm... ...yet. You have to check if the lava tube has a low resistance cut off. Charts, a good google search can show you that or the search on this forum. The IGO does not come prebuilt but once you youtube it and make your first, the intimidation goes away. Does the lava tube have a ohm meter built in?

You can find other like this for the different types of wire on google.

Watch some grim green or rip trippers videos on youtube. I hope this helps.

yeah it has a ohm meter in it. It's actually an Mvari which is basicall a lavatube v2 clone. The website where I bought has the specs and says the device has 2.5amp cut off. So I think that means I shouldn't sub ohm.

yes thanks for that chart. I've been watching lots of video's. It seems most are talking about sub-ohm micro coils and using mech mods. I think I should be building around 2 ohms. but I'm newb so not sure.

Running at 4 volts will cut of below 1.6 ohms

1. can I or should I sub-ohm on my lavatube? I think there is a 2.5 amp limit on my device.

Correct..You can't sub-ohm on your Lavatube..However you can build a higher resistance coil for your RDA and still use it.

2. can you recommend an inexpensive rda that would be good for a newbie. I would preferably like something that comes with a factory coil installed so I can see what it supposed to vape like before messing around with my own builds. I was looking at the pheonix v4 mini.

Trident clone from Hcigar..around $20 on eBay.

3. what gauge wire should I be using and how many wraps? maybe there's a good thread or chart someone can refer me too that shows what gauge/wrap to use for specific ohm's.

28 ga. Kanthal.
You can buy a cheap mechanical mod to sub-ohm with. The King clone is a good starter.
Mind you also buy some 30 to 35amp high drain batteries 18650. Efest is what I use.

I am building at 2.5 on my MVP2. 9 watts and it is awesome. Already wanna keep going!



This is 2 strands of 34 twisted on an IGO-L

I hope this video explains sub-ohm (micro) coils for you.
Build 2 of these coils and it will take you under 1.ohm
I usually do 6 wraps on each coil that is around 1. ohm for each coil
Usually I get them around .50ohm

Thanks everyone! this is why I love this forum. Ask anything and within minutes you have several answers!

ME too! After you learn, you can pass it forward as well.

Anything 1.5ohm and up should work well with your devices. 30 or 32ga wire should be good. 4 or 5 wraps on a standard coil with 30ga should get you there. 32ga will get you slightly higher ohms with the same number of wraps.

Is current what makes the heat? So higher current would be more heat?

 

[Rossum]

No, power makes heat, and Power (P) is volts (V) times current (I).

P= V * I

Moreover, volts (V), and amps (I) have a wonderful relationship with resistance (R):

V= I * R

Knowing these two equations allows us to use simple algebra to do a bit of substitution, and calculate power if we know the resistance of our coil and either the voltage across or the current through that coil:

P = I^2 * R

P = V^2 / R

i'm running an igo w single coil on an svd at 1.6 ohms and 13 watts and LOVE IT

Here is the breakdown of the Trident bro.

I should know better then. 2 Years of navy electronics training. So the sub ohmers are hitting a constant voltage, low ohms higher current and higher power! Got it. So a regulated mod will stop at a certain Watts making a peak for max Power, therefore drop the resistance for more current and more heat. P=I*E. I should have paid more attention to all of the inversely and directly proportional rules. Ug. but I am still limited at 11W max. So now I know why that was important.
