@DavidOck,
@UncleJunkle, thank you for the replies!
I usually refer to steam-engine how is the optimal power for my build, cause I like hot vapor and that's why I'd like to know what's the maximum watts as a rule, but eventually I set them by testing in practice.
I have both, the original old Pico 75w with micro usb and the new Pico Plus.
The first is with Arctic Fox and is damn good.
The second is facelifted and I bought it only for its fine look. No AF possible

But I heard, that the chip is the same, the difference is the connector and if you put micro usb, AF is upgradeable, despite
@UncleJunkle post.
Finally I will continue using the old and will keep the new as a spare one.
And won't believe the screen but the actual feeling while vaping.
Best regards and have a nice weekend
