Can I bring the charger on board？

Chargers can be brought on board the aircraft, but there are regulations for charging banks. 1. Charging banks with a capacity of less than 20000 mA can be carried on board the aircraft through security checks. 2. Those exceeding 20000 mA and less than 32000 mA must be approved by the airline before they can be taken on board. Those exceeding 32000 milliamps cannot be taken on board the aircraft. 3. It is required that the power pack be from a regular manufacturer, with a comprehensive identification and safety certification printed on it, and that no more than two power packs be carried per person.
