Think leaving your phone charger plugged in after your device is fully charged is harmless?
Think again. What seems like a harmless convenience could quietly put your home—and your safety—at risk.
Even when unplugged from your phone, chargers continue to draw a trickle of electricity. While this “vampire power” might seem insignificant, it causes internal components to wear down faster and can generate heat over time.
That small, constant energy flow can sometimes lead to overheating. A sudden voltage spike might make your charger emit smoke—or worse, start a fire.
There’s also a safety risk, especially in homes with curious kids or pets. Dangling cords and plugged-in chargers can cause shocks or other accidents when left unattended.
Bottom Line:
Unplugging chargers when not in use isn’t just about saving a bit of electricity—it’s a simple but effective way to protect your devices, your home, and the people you care about. A small habit change can prevent overheating, electrical fires, and accidents—making your everyday routine safer and smarter.
