Why You Should Never Leave a Charger in an Outlet Without Your Phone

We’ve all been there – you yank your phone free from its charger in a hurry, leaving the cable hanging out of the socket. I mean, what’s the harm, right? Leaving your charger plugged in may not seem like a big deal, but it does come with some small but significant downsides. Here’s why it’s good practice to unplug your charger when it’s not being used.

It Still Draws Power – Even When Not Charging
When you leave your charger plugged in without a device, it still draws a small amount of power. This is referred to as phantom power or vampire energy. Although the amount is small—usually less than a watt—over time, those small amounts of wasted electricity can accumulate, especially if you have several chargers left plugged in around your house.

Just to give you some perspective, one single charger left plugged isn’t going to wreak havoc on your electric bill. But if you’re looking to squeeze the most out of your energy bills, unplugging your chargers is an easy way to save electricity during downtime.

Low-Quality Chargers Can Overheat and Pose a Fire Risk
A good quality, reputable, certified charger is built to be safe when when constantly connected. But cheap, uncertified, or damaged chargers can be a safety hazard. Lower-end chargers can also lack proper heat regulation, so they can be prone to overheating, especially if they stay in an outlet for a long enough time.

 

Although the risk of a charger causing a fire is small, defective chargers or chargers with exposed wires can create hazards. If your charger ever feels warm to the touch or displays any damage (frayed cords, discoloration, or burn marks), you should replace it immediately.

Overloaded Circuits Can Be a Problem – But Not from One Charger
Some people worry that keeping a charger plugged in leads to electrical overload, but a single charger uses so little energy that it’s unlikely to cause any issues. The actual problem arises when several high-wattage devices—like space heaters, microwaves, or kitchen appliances—are plugged into the same circuit.
