Is it dangerous to leave a plugged in charger without a device?

 

Leaving a charger plugged in all the time reduces its lifespan.

Continuous heating: Even when not in use, a charger receives current, which generates heat and causes gradual internal wear.

Risk of incompatibilities: Chargers using cables or adapters from different brands are often more vulnerable to failure or overheating.

A (low) risk of fire

Although uncommon, a charger left plugged in can overheat and pose a fire hazard, especially if it is:

  • Faulty
  • Of poor quality,
  • Poorly suited to the outlet or device it is supposed to charge.

Practical alternatives to avoid these problems

To limit the risks without having to constantly unplug your chargers, try these solutions:

  • Use a power strip or adapter with a switch. This makes it possible to turn off the power at the touch of a button, without any extra effort.
  • Avoid induction chargers left plugged in. They consume up to 30% more electricitycompared to a conventional cable.
  • Optimize your charging cycles. Keep your batteries between 20% and 80% to extend their life.

A small gesture for a useful impact

Unplugging your unused chargers is a simple but effective gesture. You extend their lifespan, reduce your electricity bill and help protect your home and the environment.

Adopting practical solutions such as a power strip with a switch makes this easier, while providing more peace of mind and sustainable savings.
