Why chargers and cables cause fires
The phone gets the blame, but the charger and cable are often the weakest link.
The weakest link is rarely the phone
Modern phones have advanced battery management. The charger and cable plugged into them often do not. Low-cost chargers can lack proper insulation, overvoltage protection and temperature cut-offs.
Cables are bent, stepped on, pinched behind beds and pulled out by the wire every day. Over time, the conductors inside can break and create local hot spots.
Common warning signs
Stop using a charger or cable if you notice any of the following:
- The plug or charger gets unusually hot.
- Discoloration, melting or a burning smell.
- Exposed wires or damaged insulation near the connector.
- Charging that starts and stops when the cable is moved.
Why night-time is different
During the day, someone usually notices a hot charger or a strange smell. At night we are asleep, often with the charger next to the bed or under a pillow. That is why an early warning matters most at night.
