Should the power bank be checked in or carried with you on the plane?

You can take it on the plane, but it must comply with the relevant regulations of the Civil Aviation Administration and the airline. The specific regulations are as follows: According to the currently effective ICAO "Technical Regulations for the Safety of the Air Transport of Dangerous Goods" and China's Civil Aviation Dangerous Goods Transport Management Regulations, passengers carrying "power banks" should comply with the following regulations: First, "power banks" must To be carried by passengers for their own use. 2. "Power banks" can only be carried in hand luggage or carry-on luggage, and are strictly prohibited in checked luggage. 3. "Power banks" with a rated energy of no more than 100Wh are not approved by the airline; those with a rated energy of more than 100Wh but not more than 160Wh can only be carried with the approval of the airline. However, each passenger is not allowed to carry more than two "power banks". Fourth, it is strictly prohibited to carry "power banks" with a rated energy exceeding 160Wh; it is strictly prohibited to carry "power banks" that do not have rated energy marked or whose rated energy has not been calculated through other marked parameters. 5. Do not use "power bank" to charge electronic devices during the flight. For "power bank" with a start switch, the "power bank" should always be turned off during flight. Calculation of the rated power of the "power bank"; if the rated energy Wh (watt hours) is not directly marked on the "power bank", the rated energy of the power bank can be converted as follows: 1. If the nominal voltage of the "power bank" (V ) and nominal capacity (Ah), the value of the rated energy can be obtained by calculation: Wh=VxAh (The nominal voltage and nominal capacity are usually marked on the power bank.) 2. If the "power bank" is only marked with milliamps Hours (mAh), you can divide this number by 1000 to get Ampere Hours (Ah).

For example, the nominal voltage of the power bank is 3.7V, the nominal capacity is 760mAh, and its rated energy is 760mah÷1000×3.7V=2.9Wh..
