A power bank with 20000mAh (20000mAh) can be carried on a plane under certain conditions. The following are specific regulations and precautions:
1、 Rated energy limit of power bank
According to the regulations of the Civil Aviation Administration of China, power banks with a rated energy not exceeding 100Wh (watt hours) can be directly carried on airplanes without the need for airline approval. The rated energy of a 20000mAh power bank is usually within 100Wh (depending on the voltage, but the voltage of a typical power bank is 3.7V or 5V, so 20000mAh usually does not exceed 100Wh).
If the rated energy of the power bank exceeds 100Wh but does not exceed 160Wh, prior approval from the airline is required, and each passenger is not allowed to carry more than two power banks. However, for 20000mAh power banks, this regulation usually does not apply because their rated energy is often below 100Wh.
2、 How to carry a power bank
Power banks must be carried as hand luggage or carried with you, and are strictly prohibited from being carried in checked baggage. This is because there is a risk of combustion and explosion inside lithium batteries, and safety accidents may occur during transportation due to squeezing, collision, and other reasons.
During the flight, it is not allowed to use a power bank to charge electronic devices, and the power must be turned off throughout the entire journey. For power banks with a start switch, the power bank should always be turned off during the flight.
3、 Identification requirements for power banks
Power banks must have clear markings displaying their rated energy, voltage, and other information. If there are no parameters indicated on the power bank, it will be prohibited to bring it on the plane. Therefore, when choosing a power bank, products with clear labeling should be selected.
4、 Precautions
Before carrying a power bank on a plane, it is recommended to check the specific regulations of the airline on the flight in advance to ensure compliance with all requirements.
If the rated energy of the power bank approaches or exceeds the limit value, it is recommended to contact the airline in advance to understand relevant policies and apply for approval (although this step is usually not necessary for a 20000mAh power bank).
During the flight, please be sure to comply with the airline’s regulations and the instructions of the crew to ensure flight safety.
In summary, a power bank with a capacity of 20000 milliampere hours (20000mAh) can be carried on airplanes in compliance with relevant regulations of the Civil Aviation Administration of China and airlines. But please pay attention to complying with various regulations and precautions to ensure flight safety.
