Introduction
Power banks, also known as portable chargers, are compact, rechargeable batteries designed to charge electronic devices like smartphones, tablets, and laptops on the go. They come in various sizes and capacities, usually measured in milliampere-hours (mAh). The higher the mAh, the more charge the power bank can store, and consequently, the more times it can recharge your device.
Can You Bring Power Banks on a Plane?
Yes, you can bring power banks on a plane, but there are restrictions and guidelines you must follow. The primary concern with power banks is their lithium-ion batteries, which pose a fire hazard if damaged or short-circuited.
TSA Power Bank Regulations
The Transportation Security Administration (TSA) has specific regulations for carrying power banks on flights:
-
Carry-On Only: Power banks must be packed in your carry on bag and are prohibited in checked luggage due to the risk of fire.
-
Capacity Limits: Power banks with a maximum capacity of up to 100Wh (watt-hours) are allowed without approval. For reference, most power banks under 27,000mAh fall under this limit. Power banks between 100Wh and 160Wh require airline approval.
-
Number Limits: Generally, you are limited to carrying up to two power banks per passenger, but this may vary by airline.
The number of power banks and spare lithium ion batteries is limited per passenger, and all spare lithium batteries must be packed in carry-on bags. Spare lithium batteries are not allowed in checked luggage.
TSA screening requires that power banks and spare lithium ion batteries be easily accessible for inspection at security checkpoints.
Some airlines may have additional rules regarding spare lithium batteries and maximum capacity, so always check with your specific airline before you travel.
Why No Lithium Batteries on Planes?
Lithium batteries are restricted for safety reasons due to potential safety hazards, as they are prone to overheating and can catch fire if they are damaged or have a manufacturing defect. This is why airlines and aviation authorities have strict guidelines about how they are transported. Such incidents as fires, smoke, or explosions caused by lithium-ion batteries are the reason for these strict airline regulations.
Airline Power Bank Policies
Most airlines have similar rules regarding power banks, but always check with your specific airline for additional rules that may apply. Here are some general guidelines:
-
Delta Air Lines: Delta Air Lines allows power banks up to 160Wh with airline approval. They require individual protection against short circuits and may have additional rules for higher capacity batteries.
-
American Airlines: Follows TSA guidelines strictly.
-
United Airlines: Requires lithium batteries to be carried in the cabin.
-
Southwest Airlines: Adheres to TSA rules, allowing up to two power banks per passenger.
Is a 20,000mAh Power Bank Allowed in Flight?
Yes, a 20,000mAh power bank is generally allowed on flights, as it typically falls well under the 100Wh limit. However, always double-check with your airline for any specific restrictions.
Traveling Internationally with Power Banks
When flying internationally, you must also adhere to the regulations of the country you’re traveling to or from. While many countries follow similar guidelines to the TSA, there can be differences. For instance, the European Union and China have comparable rules but may vary in enforcement.

Packing and Using Power Banks on a Plane
Packing Tips
-
Carry in Hand Luggage: Always pack your power banks in your carry on bags. This is crucial for safety and compliance with airline regulations.
-
Keep metallic objects like coins and keys away from power bank terminals to prevent short circuits.
-
Power banks should have their exposed terminals covered or be individually protected to prevent accidental contact.
-
Avoid extreme temperatures when storing or using power banks, as extreme temperatures can damage the battery.
-
Protect from Damage: Use a protective case or pouch to prevent physical damage.
-
Avoid Overpacking: Ensure your carry-on remains within size and weight limits.
In-Flight Use
-
Use During Flight: You can use your power bank during the flight to charge your devices. Power banks with multiple USB ports let you charge multiple devices at once, helping you stay powered throughout your flight. Some power banks also offer wireless charging and efficient charging technologies, such as USB-C Power Delivery, for added convenience during air travel.
-
Turn Off When Not in Use: To conserve energy and prevent unnecessary heat generation, turn off the power bank when not in use.

Can You Take Lithium-Ion Batteries on Airplanes?
The rules for lithium-ion batteries are similar to those for power banks. Small lithium-ion batteries (like those in cell phones and laptops) are generally allowed in carry-on luggage. Large lithium-ion batteries, such as those in power tools, may have more stringent restrictions.
According to airline regulations, spare batteries—including spare lithium and spare lithium ion batteries—must be carried in your carry-on luggage and must be individually protected to prevent short circuits.
Why Do Lithium Batteries Catch Fire on Planes?
Lithium batteries can catch fire due to:
-
Overheating: Excessive heat can cause the battery to ignite.
-
Physical Damage: Dropping or crushing the battery can lead to short-circuiting.
-
Manufacturing Defects: Poorly made batteries can fail unpredictably.
-
Improper handling: Incorrect packing or storage can create potential safety hazards.
Such incidents as thermal runaway, smoke, or fire are why airlines enforce strict safety measures.
Conclusion
Traveling with power banks requires understanding and adhering to specific regulations to ensure safety and compliance. It is essential to check the capacity of your power bank and ensure it is packed in your carry-on luggage. For a smooth journey, always choose a reliable power bank that meets airline and TSA requirements. When in doubt, consult your airline for their specific policies. By following these guidelines, you can keep your devices charged and stay connected during your travels without any hitches.
