Megear Reduced Output Current / Derating

Charger appears to work, but vehicle reports slower than expected charging speed.

Possible Causes

Charger model with lower current rating than expected, Vehicle limiting current due to battery temperature, Internal thermal derating in Megear charger, Incorrect current setting on adjustable Megear model

How to Fix / Troubleshooting

Safety first: No immediate hazard, but verify that the system is operating within specifications.

  • 1. Confirm charger rating:
    • Check the Megear label for maximum current (e.g., 16 A vs 32 A).
  • 2. Check settings:
    • On adjustable models, verify the current limit setting on the charger or in the vehicle’s charging menu.
  • 3. Monitor temperature:
    • If the charger is hot, it may be derating to protect itself; improve ventilation or reduce ambient temperature.
  • 4. Test another circuit:
    • If possible, try a different outlet or circuit to rule out supply limitations.

If output remains significantly below rating under normal conditions, the internal current control circuitry may be faulty and require service.
