- 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

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.
