The devices we rely on every day — smartphones, laptops, e-bikes, lawn tools, drones, toys and more — are powered by rechargeable lithium-ion batteries. If the batteries are damaged or charged incorrectly, they can overheat, start a fire or even explode.  

National Fire Prevention Week (FPW), Oct. 4-10, is a public safety campaign to raise awareness about fire safety and prevention. This year’s theme is “Charge into Fire Safety™: Safe Charging Is a Superpower.” In recognition of FPW, the Virginia Beach Fire Department (VBFD) is highlighting the importance of safely charging lithium-ion-powered devices to prevent fires or even explosions.

Six Key Tips to Stay Safe 

  1. Use the right charger: Use the charger that came with your device or one approved by the manufacturer. Using the wrong charger can damage the battery and increase the chance of fire. 
  2. Charge on a hard surface: Avoid charging devices on beds, couches or pillows, where heat can become trapped. 
  3. Watch for warning signs: Stop using a device if it becomes very hot, swells, smokes or develops an unusual smell. A damaged battery can overheat and start a fire. 
  4. Unplug when fully charged: Don’t leave devices plugged in longer than needed. Leaving a device plugged in can increase heat and stress on the battery. 
  5. Charge larger batteries safely: Charge large items like e-bikes, scooters and power tools outside and away from exits. These batteries are larger and store more energy. Fires can grow quickly if the battery fails 
  6. Be safe on planes: Keep charging devices where you can see them. Never charge devices in overhead bins and never charge e-cigarettes or vapes on a plane. Tell a flight attendant if you notice a problem with your device, such as if it feels very hot, starts to swell, is smoking, or has a strange smell.
