    Which version of the Kick?
    The Kick-1 (and those made in China) are only a "booster", meaning that they can only boost the voltage up to meet your selected wattage. If your selected wattage would require less voltage than what's left in the battery you will be the same as unregulated until the battery depletes to that level.

    The Kick-2 regulates the voltage both up or down to give you your selected wattage.

    example:
    The 1.25 ohm build in my kayfun only requires 3.5v to give me 10 watts. So my battery would be almost dead before a kick-1 was able to regulate the wattage.
    I would be at unregulated battery voltage until then. (more than 10 watts)

    ^^^^ it's a variable wattage only not voltage

    just what do you think the Kick changes to give you a desired wattage ???? If the resistance stays the same, and you change the wattage setting, the voltage has to change to give you the new wattage.

    Sounds backward I know, but:

    With a VV device the wattage changes every time you select a new voltage.
    With a VW device the voltage changes ever time you select a new wattage.

    So you adjust the Kick to the wattage you want, and then the Kick adjusts the voltage to give you that wattage.

    I have a Kick 2 and it does seem like at some point the wattage drops down a bit. This is just my qualitative observations. I have never taken voltage measurements

    That's when it's time to change batteries. The Kick-1 kinda did a pulsing gig when the battery depleted to that level. The Kick-2 kinda goes to half power when the battery depletes to that level. Both will shut off about 4-5 hits later.

    Yeah, the specs for the kick 2 says it shuts off at 2.7V (Kick 1 was 3.2V) under load, but I notice a drop at around 3.6-3.5V (no load). I change batteries when I notice the drop. I did manage to vape down to ~3V once.

    What are you using for a coil build with your kick? I ask because I have seen some say they are using below 1 ohm coils with their kick, yet math says they would not work with at 12 watts and 4,2 V. (My math says the coils would need to be 1.4 ohms) Am I missing something?

    I'm using carto tanks with a resistance of about 3 ohms. Evolv Kick 1s can only go down to 1.3 ohms, while Kick 2s can go down to 0.5 ohms. In either case the voltage would be equal of less than what was needed to produce 10W (Kick 1) or 15W (Kick 2) or less. I.E. The Kick 2 at 15W with a 0.5 ohm coil it would output ~2.74V. So this would be the maximum voltage that a Kick 2 could output with a 0,5 coil, as any more would exceed the 15W maximum.
