    Ohms law, voltage and watts:
    ohms is the electrical resistance to electricity of your coil
    Volts divided by ohms = amps so @ 3.3 volts a 1.8 ohm coil will draw 1.83 amps
    Amps x volts = wattage (power) so on an 1.8 ohm coil on the 3.3 volt setting will give your coil a 6.05 watt burn

    3.3 volts on a 2.2 ohm coil = 1.5 amps x 3.3 volt would equal a 4.8 watt burn
    and so on...

    edit: as your battery voltage drops so will your output wattage across the coil and performance will dwindle

    I have a EVOD starter kit with the standard 3.7v 650mAh batteries and find the 2.2ohm coils are a nice match. For my 1300mAh Vision Spinner the 2.5's that came with the kit are working well. Higher ohm coils are supposed to last longer and that is a plus IMO.

    At the moment I'm vaping A Kanger tank at 1.8 ohms. Not too shabby. It works well with 2.5's as well.

    I started with a kanger mini protank with 2.5 coils and got about 25. 1.8's from fasttech. Most say they are crap, but my mvp2 says they range from 1.8 to 2.0 which is fine by me!

    I have put an order in for another 25 2.4's from fasttech because half my juices are heavy pg and the 1.8's tend to give a burn taste.

    So it all boils down to preference, and juices u like. Try different ones and don't be afraid to draw conclusions for yourself that differ from what "most" tell ya

    Wow! Once again I didn't get any subscription notices in the mail. Thanks for all the replies

    Hope you like them! But could you tell us if your battery is variable voltage or not?

    I like the 2.2's being in the middle and using a VV battery makes adjusting for juices of differing viscosity a good fit

    I Googled "cotton/Kanthal rebuilds" and found this video (here at e-cigarette-forum)

    Vapor Lady Lounge Rebuild a Protank Atomizer, eVod Atomizer A New Way - YouTube on this thread

    http://www.e-cigarette-forum.com/for...e-kanthal.html I'd love to try this! But I dunno about doing it in an 18wheeler, which is where I live under normal circumstances.

    I hear you! It makes even my hair hurt to think about watts, volts, ohms, lightning, kites, keys, and Ben Franklin. But in this case, I think of the ohms as being a dam that holds back electrical current instead of water. The lower the ohms/dam, the more the current/water flows over it.

    I don't know. Santa/Mohamed gave them to me - see this post (I have to right click on the link, look at the properties, copy/paste into my address bar to get there) Can I ask this here/now? . Because of his generosity and the juice he sent, I haven't even wanted a real cigarette in 3 days now. I love him!

    I use and build around 2 to 2.2..... I like my vape a little cooler.
