The Best Portable Power Banks to Bring on Planes and Rules for Lithium Batteries During Air Travel

Portable Power Banks and Air Travel

Portable power banks are rechargeable battery devices that store electrical energy and allow users to charge their electronic devices like phones, tablets, and laptops while on the go.

Power banks are regulated on planes due to their lithium-ion batteries, which pose a potential fire risk if damaged or overheated. The regulations are in place to ensure passenger safety and minimize the risk of battery-related fires. 

General Rules for Carrying Power Banks and Lithium Ion Batteries on Planes 

Uninstalled lithium ion batteries under 100 Wh, including power banks like the Duracell M100 and M150, can be brought on airplanes in carry-on baggage.

US Domestic Flight Battery Regulations

Rechargeable batteries can be carried in a carry-on if they are not more than 100 watt-hours (Wh) per battery. See the TSA guidelines or FAA guidelines for details. For popular US airlines' policies, please see the links below:

International Flight Battery Regulations

Lithium ion batteries, including the M100 and M150, can be carried on airplanes in carry-on bags, according to the International Air Transport Association (IATA) depending on the Wh. For details, see the IATA website section on batteries.

How to Determine Your Power Bank's Capacity

See the product details on packaging or the website for the particular specifications of your power bank. If you know mAh and voltage, you can calculate Wh using this formula: mAh ÷ 1000 × Voltage = Wh. The Duracell M100 has 55 Wh and the Duracell M150 has 91 Wh.

Packing Your Power Bank Safely

So long as your power bank is in your carry-in and not your checked bag, there are no TSA specifications on how you pack a power bank. Consider putting it in a side pocket so it is easy to find when you need it. If carrying multiple batteries, some airlines recommend storing them in separate bags (or placed in plastic bags).

Using Power Banks During Flights

You can charge devices like phones or tablets during the flight. During takeoff and landing, electronics must be stowed. Some airlines prohibit passengers from plugging power banks into in-seat power outlets for safety reasons. If it gets too hot, unplug your power bank immediately.

FAQs

Can I bring multiple power banks on a plane? You can bring multiple power banks provided that each one is no more than 100 Wh. Be sure to put them in your carry-on bag, not in your checked baggage. For details see the FAA guidelines.

Are wireless chargers or power banks allowed in carry-on bags? Yes, in fact battery powered portable power banks and wireless chargers are only allowed in carry-on luggage for most airlines. Many airlines do not allow lithium battery devices over a certain number of Whs in checked luggage.
