Leaving phone chargers plugged in when not in use may seem harmless, but it can lead to unnecessary energy consumption, higher electricity bills, and potential safety hazards. Even without charging a device, chargers still draw power, with a typical charger using about 130W per month. This adds up, especially with multiple chargers. Non-branded, low-quality chargers can consume even more power, and leaving chargers plugged in poses a fire risk, particularly if covered by items like clothing.
In addition to the financial cost, this habit wastes energy, contributing to higher electricity bills and increased pollution. While the cost per charger is small, the cumulative effect can be significant. Unplugging chargers when not in use, choosing quality chargers, and using smart outlets can help reduce these impacts, contributing to a safer and more sustainable living environment.
