What Is the Largest Power Bank Allowed on Flights?
When traveling by air, knowing the regulations regarding power banks is essential. Most airlines allow power banks with a maximum capacity of 100Wh (approximately 27,000mAh) in carry-on luggage. Understanding these limits can help ensure a smooth travel experience without unexpected issues at security checkpoints. This article delves into power bank regulations, capacity limits, and safety considerations.
What Are the General Rules for Carrying Power Banks on Flights?
Power banks are generally allowed in carry-on luggage but not in checked baggage due to safety concerns related to lithium batteries. Key rules include:
- Capacity Limit: Most airlines restrict power banks to a maximum of 100Wh or 27,000mAh.
- Carry-On Only: They must be carried in hand luggage.
- Quantity Limit: Typically, you can carry up to two power banks per passenger.

| Rule | Description |
|---|---|
| Capacity Limit | Up to 100Wh (27,000mAh) |
| Baggage Type | Carry-on only |
| Quantity Limit | Usually up to two per passenger |
How Do Airlines Define Power Bank Capacity?
Airlines define power bank capacity in watt-hours (Wh), which is calculated using the formula:
For example, a power bank rated at 20,000mAh (or 20Ah) with a voltage of 3.7V would have a capacity of:
This calculation is crucial because it determines whether your power bank complies with airline regulations.
Why Is It Important to Know the Watt-Hour Rating?
Knowing the watt-hour rating of your power bank is vital because:
- Compliance: Ensures that you adhere to airline regulations and avoid confiscation at security checkpoints.
- Safety: Higher capacity batteries pose greater risks; understanding limits helps mitigate safety concerns.
- Travel Planning: Knowing your power bank’s specifications allows you to plan your charging needs during travel.
What Is the Maximum Capacity for Power Banks on Flights?
The maximum capacity allowed for power banks on flights is generally:
- 100Wh, which is equivalent to about 27,000mAh.
This limit is consistent across most airlines and aligns with guidelines set by aviation authorities like the International Air Transport Association (IATA).

| Capacity Type | Maximum Allowed |
|---|---|
| Watt-Hours (Wh) | 100Wh |
| Milliamp-Hours (mAh) | Approximately 27,000mAh |
How Do Different Airlines Handle Power Bank Regulations?
While most airlines adhere to the 100Wh limit, there can be variations in how they enforce these rules:
- Individual Policies: Some airlines may have stricter policies or allow larger capacities with prior approval.
- Regional Differences: Regulations may vary by country; always check specific airline guidelines before traveling.
- Exceptions: Certain airlines might permit power banks over 100Wh if they are part of medical equipment or other approved devices.
Why Might Some Airlines Allow Larger Power Banks?
Some airlines may allow larger power banks under specific circumstances:
- Medical Equipment: Batteries used in medical devices may have different allowances.
- Special Approval: Passengers can sometimes request permission for larger batteries ahead of time.
- Cargo Options: Larger batteries may be allowed as cargo under specific regulations.

| Airline | Standard Limit | Notes |
|---|---|---|
| Most Airlines | 100Wh | Common limit across carriers |
| Delta Airlines | Up to 160Wh | With prior approval |
| European Carriers | Generally 100Wh | Check individual airline policies |
How Can You Ensure Your Power Bank Is Safe for Air Travel?
To ensure that your power bank is safe for air travel:
- Check Specifications: Verify that your power bank does not exceed the allowed watt-hour rating.
- Use Quality Products: Choose reputable brands that comply with safety standards.
- Inspect Condition: Ensure there are no visible damages or defects on the battery.
What Are the Best Practices for Packing a Power Bank?
When packing your power bank for air travel, consider these best practices:
- Carry in Hand Luggage: Always place your power bank in your carry-on bag.
- Cover Terminals: Use tape or covers to protect terminals from short circuits.
- Keep Accessible: Store it where you can easily access it during security checks.
