With all the tech we carry around, it’s no surprise that battery-powered devices are starting to raise alarms on flights.
From smartphones and tablets to power banks and laptops, these everyday travel companions are essential—but they also come with risks. Lithium-ion batteries, especially in tight, poorly ventilated spaces, are more prone to overheating, and it’s becoming a real issue on planes.
So what’s causing this rise in overheating incidents? And more importantly, how can you protect yourself and others when flying? Let’s break down the latest info, along with tips to keep your devices cool and your trip stress-free.
The Rise in Overheating Incidents
According to the Federal Aviation Administration (FAA), more than 60 incidents involving overheating lithium-ion batteries occurred on planes in 2022 alone. That’s a jump from previous years, and it’s a wake-up call for travelers. The compact nature of planes and the number of devices we’re all using make flights a hotspot (literally) for overheating risks.
Devices can heat up quickly, especially when packed tightly in carry-ons or left running for extended periods in cramped areas like overhead bins. Without proper ventilation or cooling, this creates the perfect storm for your battery to overheat—and we’re not talking just warm-to-the-touch, but potentially dangerous situations like smoke or even fire.
Why Do Lithium-Ion Batteries Overheat?
Lithium-ion batteries are popular because they’re efficient and rechargeable, but they’re not without their downsides. These batteries are sensitive to temperature, charge levels, and how they’re stored or used. When your device is overworked or poorly ventilated, the battery generates heat faster than it can cool down. Add the tight, enclosed space of an airplane cabin, and you’ve got a recipe for trouble.
Keep Your Devices Cool: Travel Best Practices
- Switch to Airplane Mode
If you don’t need your device connected to Wi-Fi or data, switch it to airplane mode. This not only reduces battery drain but helps prevent overheating by turning off background processes that constantly search for signals. - Turn Off Unnecessary Features
Going beyond airplane mode, switch off Wi-Fi, Bluetooth, and GPS if they aren’t needed. These features are notorious for running in the background, putting extra strain on your device and causing it to heat up. - Avoid Charging in Overhead Bins or Cramped Spaces
Keeping your device stowed away in an overhead bin while charging is a major no-no. Poor ventilation in those spaces means your device doesn’t have a chance to cool down. Instead, keep it close and monitor it while it charges. - Unplug When Fully Charged
It’s tempting to leave your devices plugged in for the entire flight, but overcharging can lead to overheating. Once your device is fully charged, unplug it to prevent excessive heat buildup. - Use Certified Chargers and Power Banks
Stick to high-quality, certified chargers and power banks. Cheap knock-offs can lack safety features, like overheat protection, making them more dangerous for in-flight use. - Monitor Your Devices
Always keep an eye on your devices during the flight. If your phone or laptop feels hot to the touch, give it a break and power it down. Better safe than sorry.
If Your Device Overheats Mid-Flight, Here’s What to Do
Sometimes, despite your best efforts, a device may overheat. If that happens:
- Power it off immediately: Stop whatever’s causing the heat.
- Unplug from the charger: Disconnect it from any power source.
- Alert the flight crew: If you see smoke or notice excessive heat, let the flight attendants know right away. Most airlines are equipped with fire containment bags designed for these kinds of incidents.
Airline Regulations on Lithium-Ion Batteries
Airlines have strict rules about traveling with lithium-ion batteries, especially spare batteries. Most require you to keep spare batteries in your carry-on, not in checked luggage, to reduce the fire risk.
- Typically, passengers are allowed to carry two spare lithium-ion batteries with a capacity between 100 and 160 watt-hours.
- For power banks or larger batteries, check your airline’s specific rules. Some may require special approval if they exceed certain power limits.
Staying Safe With Your Battery-Powered Devices
By following these simple precautions, you can minimize the risks that come with traveling with battery-powered devices. Don’t let the rise in overheating incidents scare you—just stay vigilant, follow best practices, and be prepared in case of emergencies.
Remember, keeping your devices cool means keeping your flight stress-free. Safe travels!
