Whats The Lowest Ohms I Can Go With A 20w Mod

I just got my new petri RDA and put the coils on that came with it. Installed it properly as far as i know. I dont have an ohm tester however and when i plug the Petri onto my 20W eleaf istick (to try and see if it would come up with an ohm reading) it just said 0.0 ohms.

Is this just because the istick is 20w and cant handle subohm builds?

How do i go about testing the ohms without an ohm reader  

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!  

So hi guys I been vaping since April loven it so I'm looking get something different i got the ego c twist with aspire bdc clearomizer. What should I get next I was looking to get the vision spinner 2 and istick eleaf 30w or should i just get the istick eleaf 30w or 50w. I wanted to get the vision spinner 2 from fasttech with couple of other things but I'm going to get both.  

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?  

Hey guys, so I'm new into Vaping =D, well anyways lol .

Is it a good ideia to buy a 20W Eleaf istick MOD (2200mAh . 3.0V - 5.5V . 2,0W - 20W) with a ProTank II BCC (Bottom Coil Changeable, 1,5 ohm's) ?
I will only have to change the Coil Unit.

I want a pretty good vape from it, is it going to produce a "cloud" or not ?

Thanks !  

Whats the difference between vaping on a subohm coil and a higher like 1.5 or 2 ohm coil at the same wattage? I understand why resistance of the coil matters on a mech, but whats the difference on a VW device?  

So I ordered an Eleaf Istick 50watt from Vapenw.com and when it came I tried to verify it's authenticity.
It looks legit, the only thing I noticed that's different from most I've seen is the Istick logo on the top next to the connector. I paid 44$ for it so I'm not upset it works like a beast I just wanna make 100% sure that its real just in case I need parts or such.

The code is in a format like so

0000 1111
2222 3333

I can't figure out how to enter the code, I've tried from left to right top to bottom and from top to bottom and left to right.

It does have the torque screws though which most if not all clones lack.  

can you use the eleaf 50watt and charge it at the same time? And if u can is holding it awkward because the micro-USB is on the back and not the bottom? also what are some recommendations for tanks? Thanks guys!  

Hi everyone I just got my eleaf gs air in the mail today. It came with a 1.5 coil and when I attached it to my istick 30w it is showing 1.6 ohm? I checked the coil and it says 1.5 anyone had this happen?  

I have the istick 30w and want to get the eleaf melo. I use my istick now at 15w with a eleaf gs air mini. Can I use a sub ohm tank if I can't go past 15w? Anything more than that is too strong and chokes me.
