AUT-MC-ISOAutel · MaxiCharger DC · DC Fast ChargersFree sampleMaxiCharger isolation
Autel MaxiCharger DC fails isolation/CableCheck on one connector while the peer port on the same dual-standard unit stays healthy. Because MaxiCharger DC often pairs a CCS and NACS port from a shared cabinet, techs must confirm which physical port and which cable actually failed before assuming a cabinet-wide isolation fault.
AUT-MC-NACSAutel · MaxiCharger DC · DC Fast ChargersFree sampleNACS port latch
Autel MaxiCharger DC's NACS port latch fails to lock or won't release, either preventing a session from starting because the vehicle never confirms a locked connector, or trapping the cable in the vehicle inlet after the session ends. Drivers often report a buzzing sound or visible resistance when inserting the NACS handle.

AUT-MC-THERMAutel · MaxiCharger DC · DC Fast ChargersFree samplePower stage overtemp
Autel MaxiCharger DC power stage overtemp shows up as a progressive derate during sustained high-power sessions, escalating to a full Faulted stop if airflow or ambient conditions don't improve. This is most common in summer at sites with blocked intake filters, undersized clearance around the cabinet, or back-to-back long sessions with little cooldown between them.
