IPV3 Incorrect Readout?

[AshMitchell]

Hi everyone, just a quick question, I have an IPV3 which I think is a great device however, I have just noticed something wrong with the readout I am getting from the display. I have setup my coils to a 1.1 ohm build and cranked it up to 100w and the voltage readout is 8.5v.

Now I understand that 8.5 volts is the maximum voltage output for this device, but according to ohms law to get 100w I would need a voltage of 10.48 so my question is what wattage am I really vaping at?

Would I be correct in assuming that I am vaping at 65.68 watts?

Set to 100W with a 1.1ohm coil the device is just running at it's max voltage, which as you noticed won't achieve 100w. The only way to reach 100w is with a coil under around/under .7omh

As for what wattage you are actually vaping at, your guess would make sense, although I'm not sure exactly how the IPV3 runs. I was under the impression the IPV3 doesn't have any boost circuitry but only bucks down the series voltage of two cells. If that's the case the max voltage you'll get with fresh batteries is around 8.4v and as the batteries drain the max voltage will drop to 6.8v or so (3.4v x 2 cells) so the actual wattage your vaping at could actually vary a little bit assuming I'm correct on how the IPV3 functions (lack of boost) This also means to achieve a consistent 100W you will need to build below .5ohm instead of the .7ohm since that figure only works with fully charged batteries.

Hope this helps!
