A faulty charger can start a devastating fire.

Left in the socket, it can seem too ordinary to question—until a damaged casing, loose plug, or counterfeit component turns convenience into a safety concern. Most reputable chargers pose little risk when idle, but the warning signs matter, and one check could reveal something you never thought to not…

An unused charger typically draws a small amount of standby electricity, but that does not mean it is constantly overheating or heading toward failure. Well-made chargers designed to meet applicable safety standards generally present a low risk when left plugged in.

The greater concern is damaged, poorly manufactured, or counterfeit equipment. Unusual heat, discoloration, buzzing, a burning smell, or a cracked casing should never be brushed aside.

Stop using a suspect charger, and have loose or scorched outlets checked by a qualified electrician.

At home, simple precautions matter more than fear. Keep chargers dry and uncovered, inspect cables for fraying, and keep cords away from children and pets. Buy compatible replacements from reputable sellers rather than gambling on an untraceable bargain.

Unplugging an idle charger is a sensible extra precaution, especially before a long absence. It is not a guarantee against disaster, but it removes an unnecessary powered device from the room.
