Just a quick video demonstrating the car using Shore Power when battery is fully charged. Seems awfully high power consumption for AC in range mode though...

Are we sure all 9A go to the AC? Given how many miles go to vampire load every night, some amps of those 9 might just be the vampire.
I personally do not believe so. My whole house AC unit, also operating at 240v, draws only 20 amps, and cools a 4 bedroom, 2 living room, split level house fairly effectively. It is a 2.5 ton 8 seer (yes, I know low efficiency, actually getting replaced this week as it sprung a leak).
The power consumption from the car went up by about 50% (up to about 15-16 amps) when range mode was turned off.
Hmm, I looked again - in my car in the garage it took 12A today with A/C set at 70 deg F and ambient of 95ish... but it's variable-speed, so it might be a difference in ambient vs. setpoint temp.
That said, power consumption by A/C units are not linear in nature, and you really can't compare your whole-house AC unit to the car's - your home is heavily insulated, isn't manufactured with extremely high conductivity outer skin, and isn't 50% glass. In your home, the condenser and evaporator are much larger than in the car and operate at different pressures.
I believe I read some time ago that the second-generation Prius's compressor was rated at about 3 kW at 100% load. Add to the compressor's power the fans required to move air through the condenser (if the car is sitting still) and the climate control fan inside the car, and you can see how it can easily consume that level of power.
Does that include both the compressor and the fancoil? In many cases these are separate. Are you measuring loads or is that circuit breaker size?I personally do not believe so. My whole house AC unit, also operating at 240v, draws only 20 amps, and cools a 4 bedroom, 2 living room, split level house fairly effectively.

Your A/C would work better if you shut the rear hatch and close the drivers door.
This aligns with what I heard recently:9A is pretty good for a high-efficiency A/C compressor and fan combination @ 240v. The heater is worse... 26A or so @ 240V.
So the legal requirement combined with the charging timeline and device limitations unsurprisingly means some customers took delivery of sub-60% SOC vehicles.
