Power banks have become an important travel accessory for keeping smartphones, tablets, cameras, and other devices charged during journeys. However, because power banks contain lithium-ion batteries, airlines and airport security authorities have specific rules about how they can be carried on flights.
Many passengers are unsure whether power banks are allowed in carry-on bags, checked luggage, or international flights. Carrying a power bank incorrectly can lead to delays at airport security or the item being removed.
This guide explains everything you need to know about carrying power banks on flights, including battery size limits, airline rules, carry-on requirements, checked baggage restrictions, safety tips, and frequently asked questions.
Yes, power banks are allowed on most flights, but they must be carried in carry-on luggage only.
Most airlines allow power banks up to 100 watt-hours (Wh) without special approval. Larger batteries between 100 Wh and 160 Wh may require airline permission, while power banks above 160 Wh are generally not allowed on passenger flights.
Always check your airline’s specific rules before traveling.
Can You Take a Power Bank on a Plane?
Yes, you can usually take a power bank on a plane if it meets airline and security requirements.
Power banks are considered spare lithium batteries because they store electrical energy separately from a device. Due to lithium battery safety concerns, airlines require these batteries to remain accessible in the passenger cabin.
The main rules are:
Are Power Banks Allowed in Carry-On Bags?
Yes, power banks are generally allowed in carry-on luggage.
When packing your power bank:
Security officers may ask you to remove electronic items during screening, so keeping your power bank accessible can make the process easier.
Can You Put a Power Bank in Checked Luggage?
No, power banks are generally not allowed in checked baggage.
The reason is that lithium batteries can potentially:
Problems involving batteries are easier for crew members to handle inside the cabin compared with the aircraft cargo area.
Always place your power bank in your carry-on bag.
What Size Power Bank Is Allowed on a Plane?
Airlines measure power bank capacity in watt-hours (Wh).
General guidelines:
Power banks up to 100 Wh are usually allowed without airline approval.
Common examples:
These are commonly used by travelers.
Power Banks Between 100 Wh and 160 Wh
Power banks between 100 Wh and 160 Wh may require approval from the airline before travel.
Passengers should contact their airline before flying with these larger batteries.
Power Banks Above 160 Wh
Power banks above 160 Wh are generally not accepted on passenger flights.
Are 10,000 mAh and 20,000 mAh Power Banks Allowed on Flights?
Yes, most standard travel power banks are allowed.
Examples:
These sizes are popular because they provide extra charging capacity while staying below common airline limits.
Is a 30,000 mAh Power Bank Allowed on a Plane?
It depends on the battery voltage.
A 30,000 mAh power bank can be around:
Because it may exceed the common 100 Wh limit, airline approval may be required.
Always check the watt-hour rating printed on the power bank before traveling.
How to Calculate Power Bank Watt-Hours (Wh)
Airlines use watt-hours because it provides a standard measurement for battery energy.
The formula is:
Wh = (mAh × Voltage) ÷ 1000
Most consumer power banks use approximately 3.7 volts.
Example:
20,000 mAh × 3.7V ÷ 1000 = approximately 74 Wh
This means many 20,000 mAh power banks are within the usual limit.
Can You Carry Multiple Power Banks on a Flight?
Yes, multiple power banks may be allowed if they follow airline requirements.
However:
Carrying a large number of power banks may lead to additional security questions.
Do Airlines Have Different Power Bank Rules?
Yes, airlines may have additional requirements beyond standard security rules.
Some airlines may limit:
Before departure, check your airline’s latest battery policy.
Can You Use a Power Bank During a Flight?
Rules for using power banks during flights depend on the airline.
Some airlines allow passengers to use them, while others may restrict usage during certain parts of the journey.
Always follow crew instructions during:
Why Are Power Banks Restricted on Flights?
Power banks contain lithium-ion batteries that can create safety risks if damaged.
Potential problems include:
Keeping power banks in the cabin allows faster action if a battery issue occurs.
How to Pack a Power Bank Safely for Travel
Follow these safety tips:
Never place a power bank in checked baggage.
Avoid accidental contact with metal objects by:
Do not travel with power banks that are:
A clear Wh or mAh label helps during security checks.
Common Power Bank Travel Mistakes
This can cause delays and security issues.
Large batteries may require airline approval.
Damaged lithium batteries can be unsafe.
Different airlines may have different policies.
Tips for Choosing the Best Travel Power Bank
A travel-friendly power bank should:
For most travelers, a 10,000 mAh or 20,000 mAh power bank is a practical choice.
