What to know before buying

Listing details to confirm

The listing details are inconsistent: the title and feature copy claim 250 V, while the technical details give 240 volts, and the 20000 watts entry does not align with the listed voltage and current. The feature copy also says all J1772 EVs before naming vehicle exclusions. Treat the 80 A and broad compatibility claims as listing claims, not confirmed performance. Confirm your vehicle and charger compatibility.
