Voltage/wattage for a given resistance. I am a little bit lost!

[qfivenine]

When I only had clearomisers, it was easy: bump up the voltage until it tastes burnt, then take it down a bit. Some time later, here I am with a sigelei Zmax and Vamo V4, 2 ProTank 2's and a kayfun Lite Plus. After reading a bit, I quickly changed from voltage to wattage and set it around 8.5 watts or so. Now I got interested in testing out what happens if I bump up the wattage (for a given resistance, that should increase the voltage in the background, right?). So I go up by a watt, then another one, then another. Nothing really changes that much on my Kayfun Lite Plus. The vapor might get a little warmer but it doesn't taste burnt. Do rebuildables just take so much more heat?

So, to what wattage should I set my APV's? I am now around 10 watts and my coils are usually in the 2.0 ohm range. Thanks!

What ever works. Wattage is a function of three factors Voltage, Resistance or Current. On my Portank types and my Kayfun I can run lower wattage for some reason. Keep in mind that the higher the wattage the less time you will be able to run on a battery. Here is a spread sheet to do Wattage calks if you ever need it. Will also show current/amps. Use the tab in this spread sheet called Single coil watts calculator.

Oh when using the wattage setting resistance has little to do with output. Just stay within the limits of the device.
