Can I bring a charging treasure when traveling in Hong Kong and Macao? What size can I take?

1. According to the ICAO Technical Rules for the Safety of Air Transport of Dangerous Goods (version 20 1 1-20 12), the battery (mobile power supply) cannot be checked in theory. When passengers take a flight with a charging treasure, they can only carry it in their hand luggage or carry it with them, and can't check it.

2. Except for the specifications and quantity of lithium batteries, mobile power supply cannot charge other equipment during flight. If the mobile power supply has a switch, it should be turned off during the flight.

3. The Civil Aviation Administration also stipulated in the Announcement on Provisions for Civil Aviation Passengers to Carry "Charging Bao" that the rated energy of charging treasure shall not exceed 100Wh (watt-hour) without the approval of airlines; The rated energy exceeds 100Wh but does not exceed 160Wh, which can only be carried after the approval of the airline, but each passenger is not allowed to carry more than two charging treasures. The standard voltage across the battery of the mobile power supply used at ordinary times is 3.7V, so the rated amount of 100WH should be divided by 3.7V, which is about 27AH, and the mobile power supply is 27000 mA. Similarly, the capacity of 160WH is about 43000 mA.
