It should be, as long as the power output is high enough (i.e., 10VA). If I recall correctly, I measured the voltage (but not volt-amperes) with a multimeter at the wires where my “dumb” doorbell button was previously attached early in my installation and recorded ~17-18V (from the existing 16V/10VA transformer), and my Video Doorbell v2 has been working fairly reliably since then even at this low end of Wyze’s power recommendation.
If you find that your power is inadequate, then you can still replace your transformer at some point.
Note that a recent firmware update is supposed to address connectivity issues with Video Doorbell v2. This was reportedly paused because of a cloud issue, but apparently now has been re-released. I haven’t yet seen it available to me in the Wyze app, which is offering me the update to v4.51.2.0379 and not to v4.51.2.0578 (the latest), so I don’t know if it’s necessary to get to the penultimate version before I can get the new one. 
My current issue with the Doorbell is that it has failed to activate the mechanical chime following a button press on a few occasions. Hitting Restart in the app seems to have solved that, at least temporarily, so I might have to schedule periodic restarts using an Automation if that issue recurs.
