Can We Carry 2 Power Bank In Flight? | Essential Travel Rules

Understanding Airline Regulations for Power Banks

Carrying power banks on flights isn’t as straightforward as tossing them into your bag. Airlines and aviation authorities worldwide have clear rules about lithium-ion batteries, including power banks. These rules exist because lithium batteries pose fire risks if damaged or improperly handled. Knowing these regulations helps avoid delays, confiscations, or worse—safety hazards.

The International Air Transport Association (IATA) sets global guidelines, which most airlines follow closely. According to IATA, power banks must be carried in carry-on baggage only, never checked luggage. This is because cabin crew can respond quickly to any battery-related incidents mid-flight.

When it comes to quantity and capacity, the rules get specific. Passengers can bring multiple power banks but must ensure each one stays within the allowed watt-hour (Wh) rating. Typically, power banks under 100Wh are permitted without prior approval. Those between 100Wh and 160Wh require airline approval and are limited to two units per passenger.

Why the Watt-Hour Rating Matters

The watt-hour rating measures a battery’s energy capacity. It’s calculated by multiplying voltage by ampere-hours (Ah). This number determines how much energy a battery stores and influences safety regulations.

Most standard power banks fall below 100Wh, making them easy to carry on flights. Larger capacity units—used for laptops or multiple device charging—often exceed this limit and face stricter controls.

Knowing your power bank’s Wh rating is crucial before traveling. It’s usually printed on the device or packaging. If not visible, you can calculate it using this formula:

Wh = Voltage (V) × Capacity (mAh) ÷ 1000

For example, a 5V, 20,000mAh power bank has:

5 × 20,000 ÷ 1000 = 100Wh

This means it just meets the threshold for unrestricted carriage.

Can We Carry 2 Power Bank In Flight? Exploring Quantity Limits

Yes, carrying two power banks is generally allowed as long as both meet regulatory limits and are packed correctly. Most airlines permit up to two spare lithium-ion batteries between 100Wh and 160Wh per passenger with prior approval but unlimited amounts below 100Wh.

However, individual airline policies may vary slightly. Some carriers might set stricter limits on the number of devices or total capacity per passenger for safety reasons. Always check your airline’s website before flying.

Packing two smaller capacity power banks is often easier than one large unit exceeding limits. For instance:

• A pair of 10,000mAh (roughly 37Wh each) power banks is perfectly fine.
• Two units rated at about 120Wh each require airline approval.
• Combining multiple high-capacity units above limits risks confiscation.

In summary: Two standard-sized power banks are usually no problem, but exceeding size or quantity restrictions will cause issues.

How Airlines Screen Your Power Banks

Security checks at airports involve X-ray screening of carry-on bags where batteries are visible. If agents notice oversized or numerous batteries without proper documentation or approval, they may ask questions or remove items.

Some airlines also require passengers to declare high-capacity batteries during check-in or boarding. Failure to comply can lead to denied boarding or confiscation of devices.

To avoid hassle:

• Carry devices in original packaging if possible.
• Keep batteries accessible for inspection.
• Declare any large capacity units during check-in.

Power Bank Size and Airline Approval Requirements

Here’s a detailed breakdown of what you need to know regarding size categories and approvals:

Power Bank Capacity (Watt-Hours)	Quantity Allowed	Airline Approval Required?
<= 100 Wh	No limit on quantity (generally)	No approval needed
> 100 Wh and <=160 Wh	Maximum of two per passenger	Yes, prior approval required
>160 Wh	Prohibited in both carry-on and checked luggage	N/A – Not allowed onboard

This table clarifies why most travelers don’t face issues carrying two small-to-medium-sized power banks on flights.

The Role of Checked Luggage Restrictions

Airlines strictly forbid lithium-ion batteries in checked baggage due to fire risk inside cargo holds where immediate response isn’t possible. This includes all spare batteries like power banks.

If you pack a power bank in checked luggage by mistake, security will likely remove it at screening checkpoints or airport security zones before loading onto the plane.

Always ensure your power banks stay with you in your carry-on bag throughout the journey for safety compliance.

Packing Tips for Carrying Two Power Banks Safely Onboard

Carrying two power banks safely involves more than just meeting size limits—how you pack them matters too.

• Avoid physical damage: Use protective cases or wrap devices separately to prevent short circuits caused by metal objects like keys or coins.
• Keep terminals covered: Some manufacturers provide terminal covers; if not available, tape over terminals can prevent accidental contact.
• Avoid extreme temperatures: Store your devices away from heat sources like direct sunlight during travel.
• Carry original packaging: It helps security identify the devices quickly and verify specifications.
• Lithium battery labeling: Ensure your devices have proper certification marks such as UN38.3 compliance stickers.
• Avoid overcharging: Charge your devices before boarding but unplug them during flight unless necessary.
• Lithium battery declaration: Declare any large capacity units requiring approval at check-in counters promptly.

Following these steps minimizes risks associated with carrying multiple power banks onboard aircraft.
