How to Fix / Troubleshooting
Safety: Overheating can lead to fire. If any part is too hot to touch comfortably, stop using the charger.
- Stop charging: Unplug from vehicle and mains and allow everything to cool.
- Inspect for discoloration: Look for browning, melting, or deformation on the connector, cable, and mains plug.
- Check outlet quality: Avoid old or loose wall sockets. A plug that wiggles easily in the outlet can overheat.
- Reduce current: If your J+ Booster allows, set a lower current and test again while monitoring temperature.
- Replace damaged parts: Any connector or cable showing heat damage should be replaced. If the mains outlet is suspect, have it replaced by an electrician.
