1. The rated energy of the charging treasure cannot exceed 100Wh (watt-hour), otherwise it needs the approval of the airline. 20000 mA charging treasure, calculated according to the voltage of 5V, is about 100Wh, and if it is 3.7V, it is 74Wh. So under normal circumstances, 20,000 mAh charging treasure is within the allowable range.
2. The rated energy refers to the maximum energy that the charging treasure can output when it is fully charged, in Wh. The rated energy can be obtained by multiplying the nominal voltage (V) of the charging treasure by the nominal capacity (Ah). The charging treasure is generally marked with the nominal voltage and the nominal capacity. If the charging treasure is only marked with mAh, you can divide this value by 1000 to get ampere hour (Ah).
3. Announcement 4 of the Civil Aviation Administration on the regulations for passengers to carry "lithium batteries and charging treasures" clearly points out that the rated energy value of lithium-ion batteries shall not exceed 100Wh (watt hour). Those exceeding 100Wh but not exceeding 160Wh may be installed on the equipment in checked baggage or hand luggage with the approval of the airline. It is forbidden to use lithium batteries above 160Wh. The "charging treasure" that is not marked with rated energy and cannot be calculated by other marked parameters is also strictly prohibited from flying.
4. The charging treasure must be carried with you and cannot be put in the checked baggage. This is to prevent lithium batteries from spontaneous combustion when heated at high altitude.
5. Lithium battery refers to a disposable or rechargeable battery with lithium metal or lithium alloy as negative electrode material and non-aqueous solution as electrolyte. Lithium-ion battery refers to a rechargeable battery with lithium-containing compounds as anode and cathode materials and non-aqueous solution as electrolyte solution.
6. Lithium batteries have the advantages of high energy density, low self-discharge and no memory effect, but there are also some security risks. Under abnormal conditions such as high temperature, high voltage, short circuit, overcharge or overdischarge, the lithium battery may have internal short circuit, heat, smoke, fire or explosion.
7. Announcement of Civil Aviation Administration on the Provisions of Passengers Carrying Lithium Batteries and Charging Charges in Luggage clearly points out that portable electronic equipment (watches, calculators, cameras, mobile phones, notebook computers, video cameras, etc.). ) Lithium-containing or lithium-ion batteries for personal use of passengers or crew members should be carried on board as hand luggage. The lithium content of lithium metal batteries should not exceed 2g, and the rated energy value of lithium-ion batteries should not exceed 100Wh.
The spare battery of portable electronic equipment must be protected separately to prevent short circuit and can only be carried in hand luggage. Charging treasure must be carried by passengers for their own use, and can only be carried in hand luggage or carried with them. It is strictly prohibited to carry it in checked baggage.
8. The charging treasure must have a clear logo and 3C certification, otherwise it may be detained. The identification shall include parameters such as rated energy, rated voltage and rated capacity.
9.3C certification refers to China's compulsory product certification system, which is a product conformity assessment system enforced by the government to protect consumers' personal and property safety.
10. It is clearly pointed out in the Announcement of Civil Aviation Administration on Provisions for Passengers to Carry Lithium Batteries and Charging Charges in Luggage that it is strictly forbidden to carry "Charging Charges" which are not marked with rated energy and cannot be calculated by other marked parameters. For the "charging treasure" with the start switch, it should be closed all the time during the flight.
1 1. The charging treasure cannot be used in flight or carried for personal use. This is to avoid fire or explosion caused by overcharge or overdischarge of charging treasure.
12. Overcharge or overdischarge means that the internal structure of lithium battery is irreversibly damaged during charging and discharging, which affects the performance and safety of lithium battery.
13. The Announcement of Civil Aviation Administration on the Provisions on Carrying Lithium Batteries and Charging Charges in Passengers' Luggage clearly states that "Charging Charges" shall not be used to charge electronic equipment in flight. It is strictly forbidden to carry "charging treasure" for non-personal use.
