Traveling with power banks by air requires adherence to specific safety regulations that limit size, type, and packaging. Most airlines and aviation authorities allow power banks in carry-on luggage only, restrict their watt-hour (Wh) rating typically up to 100Wh without approval, and prohibit them in checked baggage. Understanding these rules helps ensure safe, hassle-free air travel with your portable chargers.
How Do Airline Regulations Affect Traveling with Power Banks?
Airline rules mandate that power banks, powered by lithium-ion batteries, must be carried in hand luggage, not checked baggage, due to fire risks. Most airlines limit power banks to under 100Wh without requiring approval; between 100Wh and 160Wh are allowed with airline consent, with a common limit of two units per passenger. Devices above 160Wh are generally forbidden from passenger planes. Regulations may vary depending on carrier and country.
What Are the Watt-Hour Limits for Power Banks on Planes?
The standard limits are: up to 100Wh per power bank allowed without any approval; 101Wh to 160Wh allowed but only with airline approval and typically limited in quantity; over 160Wh not permitted on passenger aircraft. To calculate watt-hours, convert milliampere-hours (mAh) via Wh = (mAh × Voltage) / 1000. For example, a 20,000mAh power bank at 3.7V equals 74Wh and is allowed freely.
| Power Bank Capacity (mAh) | Voltage (V) | Calculated Watt-Hours (Wh) | Airline Approval Needed? |
|---|---|---|---|
| 5,000 | 3.7 | 18.5 | No |
| 10,000 | 3.7 | 37 | No |
| 20,000 | 3.7 | 74 | No |
| 30,000 | 3.7 | 111 | Yes |
| 50,000 | 3.7 | 185 | Not Allowed |
Why Are Power Banks Prohibited from Checked Baggage?
Lithium-ion batteries pose a fire hazard if damaged, short-circuited, or improperly handled. A fire in the aircraft’s cargo hold, where immediate intervention is difficult, could be catastrophic. Thus, safety regulations globally ban lithium-ion power banks and spare batteries from checked baggage, requiring passengers to carry them in the cabin where potential incidents can be quickly addressed.
How Should You Pack and Handle Power Banks for Air Travel?
Pack power banks in carry-on luggage only, ensuring devices are switched off and protected from short circuits by covering exposed terminals. Store them in easily accessible pockets or compartments. Labeling the power bank capacity is recommended. Avoid charging power banks inside your bag or storing them in overhead compartments during flight, as some airlines mandate visible use for safety monitoring.
Which Airlines Have Additional Restrictions on Power Bank Use?
Certain airlines, particularly in Asia and the Middle East, have imposed stricter rules, banning the use or charging of power banks inflight or restricting storage locations (e.g., Emirates bans in-flight use and charging from October 2025). Southwest Airlines in the U.S. requires power banks in use to remain visible at all times. It’s crucial to check your airline’s policies before flying.

When Should You Get Airline Approval to Travel with Larger Power Banks?
If your power bank exceeds 100Wh but is under 160Wh, you must seek airline approval before traveling. Approval processes vary by airline and can require advance notifications or special documentation. Carrying over two units of such power banks is often restricted. Batteries over 160Wh are categorically disallowed on passenger flights.
Can Power Banks Be Used or Charged During Flights?
Policies differ: many airlines prohibit charging or using power banks in bags or overhead compartments for safety reasons, requiring visible monitoring during use. Some carriers ban in-flight charging altogether after incidents involving lithium battery fires. Adhere strictly to crew instructions and airline rules regarding device usage onboard.
Where Can You Buy Airline-Compliant Power Banks with Safe Features?
Reputable brands like Redway Battery offer certified power banks designed for travel, meeting international safety standards. Their products often include protective circuits, clear labeling of watt-hour ratings, and premium quality cells to minimize fire risks. Purchasing from trusted manufacturers ensures compliance and reliability for air travel.
How Can Travelers Prepare for Airport Security Checks with Power Banks?
Always declare power banks if requested, carry proof of watt-hour rating, and keep devices accessible for inspection. Ensure power banks can power on if security requires demonstration. Use original packaging or protective pouches to avoid damage and facilitate swift screening with minimal disruption.
What Are Common Mistakes Travelers Make with Power Banks on Flights?
Frequent errors include packing power banks in checked luggage, carrying batteries exceeding allowed watt-hours without approval, not labeling or verifying capacity, and ignoring airline-specific restrictions on in-flight charging or storage locations. These mistakes can lead to confiscation, travel delays, or fines.
