The Civil Aviation Administration (CAA) has regulations that allow you to take a rechargeable battery on an airplane, but there are certain restrictions on the number of rechargeable batteries and the size of the energy, and the amount of energy you can carry, and you need to go through the CAA to get permission to carry them under special circumstances.
The Civil Aviation Administration of the provisions of carrying charging treasure
1, rated energy less than 100Wh can be brought on the plane
The Civil Aviation Administration of the mobile power to carry on the plane has made the relevant provisions, rated energy within 100Wh charging treasure can be brought on the plane, rated energy in the 100Wh 160Wh direct charging treasure, need to be through the The rechargeable batteries with energy ratings between 100Wh and 160Wh need to be approved by the airlines. The rechargeable batteries are not labeled directly with the energy rating, but only the capacity. So only after the conversion, we can know how much capacity of the rechargeable treasure can be brought on the plane.
2, formula conversion
Take 37V/10000mAh charging treasure as an example, rated energy = 3.7V times 10000mAh = 37Wh, less than 100Wh, in line with the provisions of the plane can be taken. Similarly, the most general charging treasure output voltage is 5V, according to the formula conversion, capacity = rated energy divided by the voltage, 100Wh divided by 5V is equal to 20,000mAh, so the capacity of 20,000mAh charging treasure can be brought on the plane.
3, the number of regulations
Each passenger can bring up to 2 charging treasure on the plane, and the rated energy can not be greater than 100Wh, that is, the total capacity of not more than 20000 mA. Therefore, 20000 mA charging treasure can not be brought on the airplane.
