Why is the powerbank not allowed in checked baggage?

Power Banks: Restricted in Checked Baggage for Flight Safety

Power banks, portable devices that store electrical energy to charge electronic devices, are increasingly becoming an essential travel companion for many. However, when it comes to air travel, power banks are subject to specific restrictions that may surprise some passengers.

One of the key restrictions is that power banks are not allowed in checked baggage. This regulation, implemented for flight safety purposes, stems from the potential risks associated with lithium-ion batteries, which are commonly used in power banks.

Lithium-Ion Batteries: A Potential Fire Hazard

Lithium-ion batteries, while highly efficient at storing energy, carry a inherent risk of fire if mishandled or damaged. This is because lithium-ion batteries can undergo a condition known as “thermal runaway,” where a chain reaction of chemical reactions occurs, rapidly increasing the temperature of the battery and potentially leading to a fire.

In the cabin environment, the risk of lithium-ion battery fires is particularly high due to factors such as:

• Extreme temperature fluctuations: The cabin temperature can vary drastically during take-off, landing, and turbulence. These temperature changes can stress the battery, increasing the risk of a malfunction.
• Physical impacts: Checked baggage is subjected to rough handling during loading and unloading, which can cause damage to the battery or its casing.
• Possibility of short circuits: The presence of other electronic devices or metal objects in checked baggage could potentially cause a short circuit in the battery.

Restricting Power Banks to Carry-On Baggage

To mitigate these risks, airlines have implemented strict rules that restrict power banks to carry-on baggage only. By keeping power banks in the passenger compartment, any potential malfunction or overheating can be more easily detected and addressed.

Allowed Capacity Limits

In addition to the general restriction, there are specific limits on the capacity of power banks allowed on flights. Most airlines limit the capacity of power banks to 100 watt-hours (Wh). Power banks with a capacity exceeding this limit are not allowed on board either in carry-on or checked baggage.

Compliance is Crucial

Passengers are strongly advised to comply with these regulations regarding power banks. Failure to do so could result in the power bank being confiscated at the security checkpoint or, in some cases, the passenger being denied boarding.

Alternative Options for Checked Luggage

If travelers need to carry bulky electronic devices that require charging, they should consider using non-battery charging solutions, such as portable chargers that can be plugged into an electrical outlet. These options are typically allowed in checked baggage as they do not pose the same fire risks as lithium-ion batteries.

By adhering to these restrictions and following proper handling guidelines, passengers can ensure the safety of their electronic devices and contribute to a safe and secure flying experience.
