Can wireless chargers be taken on airplanes and through security scanners?

Basic Regulations for Carrying Chargers on Board

According to the Civil Aviation Administration of China's "List of Items Prohibited for Carry-on and Checked Baggage by Civil Aviation Passengers" and the International Air Transport Association (IATA) guidelines, ordinary chargers (such as mobile phone and laptop chargers) can be carried on board or checked baggage, but must meet the following conditions:

Power Limits: There are no explicit power limits for chargers without built-in batteries, but power banks with lithium batteries must have a single rated energy ≤100Wh (approximately 27000mAh). Exceeding this limit requires airline approval.

Quantity Limits: Each passenger may carry ≤2 compliant power banks, and these are prohibited from being checked in.

Security Screening Requirements: Chargers must be inspected separately and should not be stacked with other electronic devices to avoid obstructing X-ray imaging.

Precautions for Special Chargers

Wireless Chargers: If containing magnetic components, they must pass through a security scanner to test the magnetic field strength (usually household products meet the standards).

Car Chargers: Permitted to carry, but prohibited from use on board.

Multi-functional Charging Stations: If containing large-capacity batteries or tools (such as screwdrivers), they may be classified as dangerous goods and must be declared in advance.

Common Issues and Misconceptions

"Chargers will interfere with aircraft signals": The Civil Aviation Administration of China (CAAC) has clearly stated that chargers that meet 3C certification will not interfere with avionics equipment, but the power must be switched off during takeoff/landing.

"All lithium batteries are prohibited from being checked in": This applies only to portable power banks and other power banks. Devices with built-in batteries (such as cameras) can be checked in, but the battery level must be ≤30%.

Practical Advice
Place the charger in your carry-on baggage to avoid damage or loss during check-in.

Check in advance to ensure the power bank's capacity label is clear; unclear labeling may result in confiscation.

International flights are subject to additional regulations of the destination country (e.g., the US TSA has a separate inspection process for power banks).
