How many milliamps does an airplane power bank have? Hot topics and data analysis in the past 10 days

As demand for air travel rebounds, regulations on carrying power banks on planes have once again become a hot topic. In the past 10 days, the number of relevant discussions on Weibo, Zhihu, Douyin and other platforms exceeded 500,000 times, and the popular science content published by the official account of the Civil Aviation Administration of China received 120,000 reposts. This article will combine the latest data and regulations to answer the capacity issues that travelers are most concerned about.

1. Comparison of power bank capacity regulations of domestic airlines

2. Hot search related topics in the past 7 days

3. Core knowledge points of capacity conversion

According to ICAO regulations, the actual judgment standard isWatt-hours (Wh) instead of milliamperes (mAh). The conversion formula is: Wh = mAh × voltage (V) / 1000. Take the common 3.7V power bank as an example:

4. Passengers’ actual test experience sharing

Collecting 300 latest feedback from social platforms shows:

• 78% of passengers carrying power banks below 20,000mAh successfully passed inspection
• 15% were required to be deposited due to lack of capacity identification
• 7% reported differences in implementation standards at different airports

5. Professional advice

1. Select when purchasingClearly mark the mAh and Wh parametersproducts
2. Wrap the electrodes with insulating tape before boarding the plane
3. The preferred capacity is in the 16000-20000mAh range (57-74Wh)
4. Avoid using second-hand or bulging products

Civil aviation experts remind that high temperatures in summer may affect the stability of lithium batteries, and it is recommended that passengers reserve more than 20% of the battery before boarding. Recently, airports in Shanghai, Guangzhou and other places have added special testing equipment for power banks. Please cooperate with security personnel to take them out for inspection individually.
