Tesla Mobile Connector - Charging Rate Reduced / Overheating WarningUpdated 3 hours ago

Quick Fix (90% Success Rate)

The most common cause is a loose adapter connection. Even if it looks connected, it probably isn't seated properly.

Immediate Steps:

1. Stop charging and unplug everything
   • Let equipment cool for 5-10 minutes
2. Remove and reinstall the adapter with significant force
   • Pull the adapter completely out of the Tesla Mobile Connector
   • Push it back in MUCH harder than you think necessary
   • Most people don't push hard enough - it requires substantial force
3. Test the connection
   • Try to wiggle the adapter
   • If it moves at all, it's not properly seated
   • Remove and push in harder until completely secure

Prevent Future Issues

Mount Your TMC Sideways

• Vertical mounting allows gravity to slowly pull the adapter loose
• Horizontal/sideways mounting keeps the adapter secure
• Support the cable weight with a hook or holder

Regular Maintenance

• Check adapter connection monthly
• Clean contacts with isopropyl alcohol quarterly
• Inspect for damage or wear

If the Problem Persists

After confirming the adapter is properly seated:

1. Reduce charging current temporarily
   • Set current to 50% of breaker rating or lower in your Tesla
   • Monitor if warnings continue
2. Check your electrical connection
   • Feel the wall outlet while charging (warm is normal, hot is not)
   • Look for burn marks or melting on outlet/plug
   • Verify stable voltage with multimeter (240V ±5%)
3. Inspect for physical damage
   • Bent or corroded pins on adapter
   • Melting or discoloration on any component
   • Damaged cable insulation

When to Replace Equipment

Contact support if you see:

• Visible melting or burn marks
• Persistent issues after confirming tight connections
• Damaged or bent pins
• Error continues across multiple charging locations
