What type of power banks are not allowed on planes?

Power Banks on Planes: Understanding Airline Regulations

Power banks, essential devices for keeping our gadgets charged on the go, are subject to certain restrictions when traveling by air. These regulations are in place to ensure passenger safety and minimize potential hazards.

Allowed Power Banks

• Lithium-ion batteries: These are the most common type of power bank batteries.
• Capacity: Power banks with a capacity of 100 Watt-hours (Wh) or less are generally allowed on planes without any restrictions.

Restricted Power Banks

• Power banks exceeding 160 Wh: These high-capacity power banks are not allowed on planes.
• Power banks between 101-160 Wh: These medium-capacity power banks require prior approval from the airline before they can be taken on the flight.

General Guidelines

• Check airline policies: Different airlines may have slightly different regulations regarding power banks. It’s important to check with your specific airline before flying.
• Carry-on only: Power banks must be carried in the cabin baggage and not checked in.
• Protect batteries: Avoid overcharging or exposing power banks to extreme temperatures.
• Declare larger power banks: If your power bank exceeds 100 Wh, you must declare it to the airline and provide the airline with the exact Wh rating.

Why the Restrictions?

The restrictions on power banks are primarily due to the potential fire hazard posed by lithium-ion batteries. These batteries can overheat and ignite under certain conditions, such as when they are damaged or overcharged. By limiting the capacity of power banks allowed on planes, airlines can mitigate the risk of a fire incident.

Alternatives to Power Banks

If you need to power your devices during a long flight, consider using other options such as:

• External battery packs that are less than 100 Wh: These are typically smaller and lighter than power banks.
• Portable chargers with built-in solar panels: These allow you to charge your devices using the sun’s energy.
• USB power adapters: You can plug these into the plane’s power outlets to charge your devices.

By following these regulations and guidelines, passengers can safely bring their power banks on planes and keep their electronic devices charged for use throughout their journey.
