HMD Touch 4G 3 days ago

This is nothing new. It's a dumb-phone with a touchscreen. There were quite a few examples back in the day in the late 00s.

I'd like to use it because I support the creator's stated mission, but for me, performance seems very slow and unreliability is lacking

Nothing "directly" runs on 12V either. All electronics will have stepdown converters in both the 12V and 48V use case. Motors, solenoids and incandescent bulbs can be made to work with either voltage (the same way we do for 24V systems in heavy goods vehicles here in Europe).

Maybe the car has an AC compressor or a pump to cool the battery during charging, which draws directly from the charger when plugged in

No it doesn't. A/C compressors in EVs are 3 phase AC powered by an inverter supplied by the traction battery.

The contactors in an EVSE open and close at practically zero current, the OBC ramps the current up or down accordingly. And as another sibling comment noted, the OBCs are PFC corrected and act as a largely resistive load.
