Starting Friday, May 1, American Airlines is implementing stricter rules on portable chargers, affecting an estimated four million British travellers who fly to the US annually. The airline now limits passengers to two portable lithium chargers in carry-on luggage, each not exceeding 100 watt-hours. Additionally, these devices must be kept visible and within reach during the flight—meaning they cannot be stored in overhead lockers or recharged using in-seat power outlets.
Why the New Rule?
Power banks contain lithium-ion batteries, which are known fire hazards if damaged or faulty. The Federal Aviation Administration reported 39 incidents involving lithium batteries in 2025 alone, and 228 incidents from March 2006 to March 2026. Recent events include a KLM flight to Amsterdam in August 2025 where a charger overheated, and an Air China flight to South Korea that made an emergency landing in October 2025 after a battery ignited.
American Airlines' Statement
An airline spokesperson said: 'We know our customers rely on portable chargers to keep devices powered throughout their journey. To support safety on board while ensuring our customers continue to have the ability to charge when on the go, American is requiring customers to keep these devices easily accessible during flight.' The airline added that the policy 'aligns with industry standards and underscores America's commitment to safety—our top priority.'
Previous Policy vs. New Policy
Previously, American Airlines allowed up to four power packs with lithium batteries in carry-on, and passengers could travel with two spare batteries between 100 and 160 watt-hours. The new rule reduces the limit to two power banks, all under 100 watt-hours, and bans storage in overhead bins and in-flight charging.
Other Airlines with Similar Bans
American Airlines follows Southwest Airlines, which on April 20 limited passengers to one power bank per person, also banning overhead bin storage and charging. Other airlines that have banned or restricted power banks include Tigerair, Air Busan, Lufthansa Group, Emirates, Singapore Airlines, Cathay Pacific, Qantas, Thai Airways, South Korean Airlines, Hong Kong Airlines, and Starlux Airlines.
What Travellers Should Do
Passengers flying American Airlines from May 1 should ensure they carry no more than two power banks, each under 100 watt-hours, and keep them accessible in their carry-on bag. Charging the power bank during the flight is prohibited, and devices must not be placed in overhead bins.
