Thai Airways, Singapore Airlines & Scoot Prohibit Power Bank Charging Onboard

Considering recent safety concerns, several prominent airlines, including Thai Airways, Singapore Airlines (SIA), and its subsidiary Scoot, have announced bans on the use and charging of power banks during flights. These measures aim to enhance passenger and crew safety following incidents involving overheating lithium-ion batteries.

Thai Airways’ Proactive Measures

Effective from 15 March 2025, Thai Airways will prohibit passengers from using or charging power banks onboard its aircraft. While travellers can still carry these devices in their hand luggage, in-flight usage is strictly forbidden. This decision aligns with guidelines from the Civil Aviation Authority of Thailand (CAAT), which also bans power banks in checked baggage due to potential fire hazards associated with lithium batteries. The airline’s move responds to a series of in-flight fire incidents on international carriers, some linked to power bank usage. By implementing this ban, Thai Airways underscores its commitment to maintaining the highest safety standards for its passengers and crew.

Singapore Airlines and Scoot Implement Similar Bans

Following suit, Singapore Airlines and its budget subsidiary, Scoot, will enforce similar restrictions starting 1 April 2025. Passengers on these carriers will be prohibited from using power banks to charge personal devices during flights. Additionally, charging power banks via onboard USB ports will not be allowed. However, customers may still bring power banks with a capacity of up to 100 watt-hours (Wh) without special approval. Devices between 100Wh and 160Wh require airline approval, and those exceeding 160Wh are entirely prohibited. These measures are in line with the International Air Transport Association’s (IATA) Dangerous Goods Regulations concerning lithium batteries.

Catalysts for the New Regulations

The stringent policies stem from several incidents involving power banks. In January 2025, an Air Busan flight in South Korea experienced a fire while preparing for departure, reportedly caused by a power bank. This incident led to injuries and significant aircraft damage, prompting Air Busan to ban power banks in hand luggage, requiring passengers to keep them on their person instead. Other airlines, such as EVA Air and China Airlines, have also adopted similar measures, reflecting a broader industry trend towards stricter regulations on portable chargers.

Understanding the Risks of Lithium-Ion Batteries

Lithium-ion batteries, commonly found in power banks, are known to produce dangerous heat levels, potentially leading to ignition or short circuits. Factors such as manufacturing defects, physical damage, or exposure to high temperatures can increase these risks. Given the confined environment of an aircraft cabin, any fire hazard poses a significant threat, making preventive measures crucial.

Guidelines for Passengers

Passengers planning to travel with power banks should adhere to the following guidelines:

• Carry-On Only: Power banks must be transported in carry-on baggage and are prohibited in checked luggage.
• Capacity Limits: Devices up to 100Wh can be carried without special approval. Those between 100Wh and 160Wh require airline consent, while devices over 160Wh are banned.
• In-Flight Usage: Usage and charging of power banks during flights are prohibited on airlines enforcing these new regulations.
• Pre-Flight Preparation: Travellers are advised to fully charge their electronic devices before boarding and utilise in-seat power outlets or USB ports provided by the airline, where available.

Global Industry Response

The aviation industry continues to adapt to the challenges posed by personal electronic devices. While UK airlines currently allow the use of power banks during flights, they encourage passengers to use built-in charging ports instead. The recent incidents have heightened awareness of the potential dangers associated with lithium-ion batteries, prompting airlines worldwide to reassess and tighten their safety protocols.

No More Charging Onboard

The bans implemented by Thai Airways, Singapore Airlines, and Scoot on the in-flight use and charging of power banks reflect a proactive approach to passenger safety. As technology continues to evolve, airlines must balance passenger convenience with stringent safety measures. Travellers are urged to stay informed about airline-specific regulations regarding electronic devices and comply with safety guidelines to ensure a secure and comfortable journey.
