Say goodbye to in-flight charging: Airlines ban devices during flights – Here's what you need to know

Flying used to be a great opportunity to recharge your phone, tablet, or laptop while enjoying offline entertainment or supposedly getting work done at 35,000 feet. However, if you're traveling through Asia, that habit might soon be grounded.

Several major airlines are tightening restrictions on the use of power banks in-flight, citing them as the cause of an increasing number of onboard fires.

Why are power banks being banned on flights?

Investigators suspect a portable lithium-ion power bank caused a fire on an Air Busan flight in South Korea earlier this year. The fire broke out while the plane was still on the tarmac, and the transport ministry later confirmed it found “electrical melting marks” on the remains of the battery.

Lithium-ion batteries, commonly used in phones, laptops, and power banks, are efficient but can be dangerous if damaged, overheated, or poorly manufactured. The FAA has reported over 500 incidents involving lithium battery-related smoke, fires, or overheating in US airspace over the last two decades.

Which airlines are changing their charging rules?

South Korea has taken the lead with new regulations, banning the charging of power banks on flights. These devices can no longer be stored in overhead bins, but must be kept under seats or in seat pockets.

Additionally, outlets must be covered with tape or protective pouches to prevent accidental contact with metal objects, the primary danger. Thailand’s national carrier, Thai Airways, has gone even further, completely banning the use and charging of power banks since March 15. Singapore Airlines will follow suit in April, with other airlines like Air Asia, EVA Air, China Airlines, Uni Air, and Hong Kong Express also introducing similar rules. Hong Kong’s aviation authority has implemented stricter storage and usage protocols as well.
