Taipei: Two of Taiwan's major carriers began enforcing new restrictions on portable power banks Tuesday, limiting passengers to two devices in carry-on luggage and banning their use for in-flight charging, with two other airlines set to follow on Wednesday.

According to Focus Taiwan, EVA Airways and China Airlines implemented the measures immediately, while Starlux Airlines and Tigerair Taiwan said they would adopt the same rules starting April 1. The policy follows updated safety guidance from the International Civil Aviation Organization. In response to these international standards, Taiwan's Civil Aviation Administration under the Ministry of Transportation and Communications convened local airlines to roll out standardized protocols.

Taoyuan International Airport Corp. Vice President Yu Chung-li stated that the airport is assisting with public awareness efforts. Lithium batteries and power banks remain banned from checked baggage due to fire risks, while security checks will ensure compliance in carry-on luggage.

Yu added that airport retailers in restricted departure areas have also been asked to inform customers of the two-device limit and the in-flight charging ban at the point of sale.
