Essential Knowledge: Traveling with Lithium Batteries

Smartphones. Laptops. Tablets. E-readers, wireless chargers, digital cameras, and more – if you can recharge it, it has a lithium battery inside. And newly updated regulations from the Federal Aviation Authority (FAA) dictate that travelers must take certain precautions when bringing these devices (plus any spare batteries) on board an aircraft.

So, which devices do these new restrictions affect? Where are travelers allowed to pack these lithium battery-powered items? And what does it mean for your next trip? We break down everything you need to know below.

1. Is my device powered by a lithium battery?
If you can recharge it by plugging it into the wall (or a portable charger), then yes, it is. Lithium-ion and lithium metal batteries power everything from smartphones and laptops to smart watches and even some rechargeable toothbrushes. Most travelers carry a handful of lithium-powered devices, so it's crucial to know how to travel safely with these items.

2. What are the risks of lithium-powered devices?
While minimal, these lithium batteries do carry risk of overheating and catching fire, and/or creating sparks or excessive heat that could ignite nearby items. According to the New York Times, this risk increases markedly when the device or battery is damaged. For example, if a smartphone or tablet has a cracked screen, that indicates that the device has undergone a high degree of force, which may have damaged the battery inside

3. How do I safely travel with my lithium-powered devices and lithium batteries?
Essentially, keep them close at hand. According to the newest FAA regulations, all lithium-powered devices and lithium batteries need to be either kept on your person or packed in your carry-on luggage. So, don't pack any of these devices in your checked luggage, and if you're asked to gate-check a carry-on, be sure to remove and carry onto the plane any laptops, tablets, chargers and the like before leaving your bag with the gate agent.

You should also be sure to inspect any lithium-powered devices for damage before traveling. If the battery shows any signs of swelling or leaking, is not performing  as well as usual, or is prone to overheating, leave the device at home or replace the battery before traveling.

If you have to check a lithium-powered device or lithium battery, the item must be "completely turned off, protected from accidental activation and packed so that they won’t get damaged," according to the official FAA website.

4. What about butane-powered devices?
Some cordless hair curlers and hair dryers are powered by butane cartridges. These items are now banned from checked luggage, and travelers are only allowed to carry one such item in their carry-on baggage.
