Never leave your charger plugged into a wall outlet without your phone. Here are the top three reasons.

It’s a very good practice to unplug chargers when they’re not in use. Here’s a breakdown of the top three reasons why:

1. Energy Waste (Phantom Load):

  • Even when not actively charging a device, a plugged-in charger still draws a small amount of electricity. This is known as “phantom load” or “vampire power.”
  • While the amount of energy consumed by a single charger is minimal, it adds up over time and across multiple devices in your household.
  • This unnecessary energy consumption contributes to higher electricity bills and a larger environmental footprint.

2. Fire Hazard:

  • Chargers, especially older or lower-quality ones, can overheat when left plugged in for extended periods, even without a device connected.
  • This overheating can lead to malfunctions, melting, and in rare but serious cases, fires.
  • Voltage surges or fluctuations in your electrical system can also increase the risk of overheating and fire.

3. Wear and Tear:

  • Constantly being plugged in exposes the charger’s internal components to continuous electrical flow, which can accelerate wear and tear.
  • This can shorten the lifespan of your charger and reduce its efficiency.
  • Additionally, electrical fluctuations can damage the internal components of the charger over time.

Therefore, unplugging your chargers when they are not actively in use is a very good habit to adopt, for safety, and to save energy.
