Power Bank Rules on Flights 2025: Cabin or Checked?

With smartphones, tablets, cameras, and laptops being essential travel companions, carrying a power bank is now as common as a passport. But if you’re flying, especially internationally, there are specific airline and airport regulations on where and how you can bring power banks.

Here’s the latest 2025 guide to understanding power bank rules for air travel — from watt-hour limits to whether they go in your cabin or checked luggage.

Are Power Banks Allowed on Flights?

Yes, power banks are allowed on most flights, but they must follow strict conditions.

  • They must be carried in cabin baggage (hand luggage), not checked-in baggage
  • Their capacity must not exceed the allowed limit, usually up to 100Wh without airline approval
  • Some airlines may require you to declare them at check-in or during security screening

Failing to follow these rules can lead to the power bank being confiscated at the airport or denied boarding.

Why Are Power Banks Restricted?

Power banks contain lithium-ion batteries, which can pose a fire risk if damaged, overheated, or improperly stored. Since fires in the cargo hold are harder to detect and control, most aviation authorities only allow them in the cabin, where cabin crew can respond quickly in an emergency.

This is why even if your power bank seems safe, placing it in checked baggage is not allowed.

Airline Power Bank Policies (2025 Overview)

Here’s a quick look at major airline policies regarding power banks:

What Is the Maximum Power Bank Capacity Allowed?

Power bank capacity is measured in watt-hours (Wh), not just milliamp hours (mAh). The standard limits are:

  • Up to 100Wh: Allowed in carry-on without approval
  • Between 100Wh and 160Wh: Allowed in cabin, but requires airline approval
  • Above 160Wh: Not permitted on commercial flights

To convert mAh to Wh:
Wh = (mAh × V) ÷ 1000

For example, a 20,000mAh power bank at 5V = 100Wh, which is allowed.

Tips for Traveling with Power Banks

  1. Always pack your power bank in your carry-on
    Never check it in, even by mistake.
  2. Look for the capacity label
    Ensure the Wh rating is printed clearly. If it’s not visible, security may confiscate it.
  3. Keep it easily accessible
    You may be asked to remove it from your bag during screening.
  4. Limit the number
    Some airlines allow only 2 or 3 power banks per passenger. Don’t overload your carry-on.
  5. Use a certified brand
    Cheap or unbranded power banks without proper certifications are more likely to be flagged.

Frequently Asked Questions (FAQs)

Can I bring a 20000mAh power bank on a plane?
Yes, as long as it’s under 100Wh (most 20000mAh models are around 74–100Wh). You must carry it in your cabin bag.

Is it safe to use a power bank during the flight?
Generally, yes — but you must not charge it unattended, and some airlines may request you not to use it during takeoff and landing.

What happens if I accidentally pack it in my checked bag?
Your bag may be flagged during security checks. Some airports may remove the item and send you a notice, while others may delay or deny the baggage entirely.

Can I carry multiple power banks?
Yes, but most airlines limit it to 2 or 3 units per person. Check with your airline before flying if you’re unsure.

Are power banks allowed on international flights?
Yes, but rules vary slightly by region. Always confirm the airline and destination country’s policy.
