Most of us are guilty of leaving our phone chargers plugged in, even when we’re not charging anything. It seems harmless—but that tiny plug quietly draws power all day long. One charger uses around 1.5 kWh per year, and when you add multiple chargers in one household, it adds up in both energy waste and money over time.
Beyond the cost, there’s a hidden danger. Cheap or worn-out chargers can overheat when left plugged in continuously, increasing the risk of sparks or even a fire—especially if they’re behind furniture or covered by clothes or paper. It only takes one overheated cable to turn convenience into disaster.
And while one charger may only cost pennies a year, dozens of small “always-on” electronics in your home add up, slowly raising your electric bill without you realizing it. It’s energy you’re not using—but still paying for.
So the takeaway is simple: unplug your charger when you’re done. It’s safer, it saves energy, and it helps cut your power bill. One small habit change, big benefits.
