A 20000 mAh charging treasure can generally pass the security check.

In China, according to the regulations of the Ministry of Public Security of the State Railway Administration, passengers are prohibited from carrying lithium batteries or charging treasures exceeding 65,438+000 Wh, but charging treasures of 20,000 mAh are usually allowed.

When carrying a charging treasure, you need to pay attention to the following points:

The charging treasure must meet the specifications and safety requirements of the Civil Aviation Administration of China, with clear signs and brand information.

The rated energy of the charging treasure shall not exceed 100Wh, which means that the capacity of the charging treasure shall not exceed 27777 mA.

Charging treasure must be put in hand luggage, not in checked baggage.

Never use a charging treasure to charge electronic equipment during the flight. You must turn off the charging treasure or put it in a safe place.

In short, if you want to carry a 20,000 mA charging treasure, you need to ensure that it meets the relevant regulations and requirements, and follow the airline's safety guidelines. If you are not sure whether you can carry a charging treasure, you can consult the airline staff or the security department of the local airport.
