1. Generally, the maximum output voltage of charging treasure is 5V. According to the formula, capacity = rated energy divided by voltage, 100Wh divided by 3.7V equals 27000 mA, so a charging treasure with a capacity less than 27000 mA can be taken on the plane.

2. The mobile power supply must be produced by a regular manufacturer with detailed product parameters, such as manufacturer information, manufacturer address, rated power of the mobile power supply, etc. Mobile power supply can only be carried with you, and it must be turned off when boarding, and it cannot be checked.

3. Don't use charging treasure to charge electronic equipment in flight. For the charging treasure with the start switch, it must be turned off during the flight.
