4 Ground Rules for Safe Charging
To protect your home and family from preventable electrical fires, fire departments recommend implementing these four simple charging habits tonight:
-
Charge on Hard, Flat Surfaces Only: Always place your phone, tablet, or laptop on a solid, unyielding surface while it is plugged in. Desks, nightstands, kitchen countertops, or wooden tables allow air to circulate freely around the device, keeping it cool.
-
Ditch Cheap, Knock-Off Chargers: It is tempting to buy cheap, unbranded replacement cables and charging blocks from online discount retailers or gas stations. However, these rarely undergo the rigorous safety testing required for major brands. They often lack built-in circuit protection, meaning they can easily overcharge a phone or short-circuit, sparking a fire. Look for certified accessories (like UL-listed or manufacturer-approved cords).
-
Inspect Cords for Wear and Tear: Over time, charging cables get bent, twisted, and frayed—especially near the connector tip. Damaged internal wiring can cause electrical arcing (electricity jumping across gaps), which can instantly ignite nearby dust, carpets, or bedding. If a cord is frayed or the plastic casing is split, throw it away.
-
Unplug Once Fully Charged: Leaving a phone plugged in for eight hours straight when it only needs two hours to reach 100% puts unnecessary stress on the battery. Whenever possible, charge your devices while you are awake and alert, and unplug them before you go to sleep.
What to Do if a Device Swells or Smokes
If you ever notice that your phone or charger is hot to the touch (not just warm), smells faintly of plastic melting, or the screen/back panel appears to be warping or swelling, act immediately:
-
Disconnect the power source safely by pulling the charging block directly out of the wall outlet rather than yanking the cord.
-
Move the device away from flammable materials like papers, curtains, or bedding if it is safe to touch.
-
Never throw water on a lithium-ion battery fire. Water can react violently with the lithium. If a device actively catches fire, evacuate the room immediately, close the door behind you to contain the smoke, and call emergency services.
The Smoke Detector Check: Because a bedroom fire can turn fatal in less than three minutes, firefighters emphasize that a charging habit shift must go hand-in-hand with working smoke alarms. Ensure you have a functioning smoke detector installed inside every bedroom and directly outside sleeping areas to give your family the vital seconds needed to escape
