Rules Around Charging Your Phone In-Flight
Landing with a fully charged phone is essential for most travelers—you’ll likely need it to book an Uber, check directions, or pull up your hotel reservation details. While it may be tempting to plug in as soon as you board the plane to ensure maximum battery life on arrival, keep in mind that most airlines now have specific rules about in-flight charging.
From how you can use power banks to unplugging during takeoff and landing, here’s what you need to know about keeping your devices powered up on a plane.

Smart Charging Tips for Travelers
- Charge before boarding: Use airport charging stations or plug in at your gate before takeoff.
- Bring the right accessories: Pack cables for all your devices, plus a universal adapter if flying internationally.
- Choose the right power bank: Select a high-capacity but airline-approved model (under 100Wh).
- Use low-power mode: Reduce battery drain by dimming screens, closing apps, or switching to airplane mode when you don’t need Wi-Fi.
- Consider bringing backup entertainment: Such as a book or using the in-flight entertainment, so you aren’t relying solely on your phone.
These days, many seats are equipped with in-seat power outlets and/or USB ports, making charging easy. However, access to these isn’t guaranteed. Business and first-class passengers almost always have power outlet options, while economy passengers may have two outlets for three seats or none at all. The voltage of the outlets is often not very high, either, so your phone will take longer to charge.
Before you fly, look up your airplane’s model and check if outlets will be available at your seat.
A power bank is my preferred charging option when I fly; it’s convenient and guarantees I can charge my phone. However, not all power banks are allowed on flights. Most airlines only allow power banks under 100Wh. It’s also important to note that according to the FAA and TSA, lithium-ion battery-powered power banks must be carried on and cannot be checked, as they may overheat and become a fire hazard.
Some airlines have started requiring that any portable charger that is in use be visible. This is due to the risk of an overheated charger catching fire. As you can see from this running list compiled by the FAA, incidents involving lithium batteries, such as smoke, fire, or extreme heat, are extremely common. The new rule by Southwest allows portable chargers to remain in your luggage as long as it is powered off. While Southwest is the first domestic airline to initiate this rule, other airlines may follow. It's a good rule of thumb to keep a power bank that is turned on out of your carry-on.
Most airlines announce that you cannot have anything plugged in during take-off and landing, which is due to passenger safety. Cords can become a tripping hazard, so be sure to unplug before your flight takes off and just before you land.
Remember that not all airlines have the same rules; some may be stricter than others, especially when it comes to international airlines. Domestic flights within China require that power banks display a clearly visible 3C certification label. It’s important to note that if you plan to fly within China, most international power banks do not have the required certification, so you may need to purchase a compliant power bank upon your arrival in China. Always review your airline’s policies in advance, usually found in the “baggage” or “dangerous goods” section of their website.
Staying prepared is the best way to ensure your phone stays charged while flying. Stick to these tips, and you should be good to go:
