Can you bring a 20000 mAh power bank on a plane?

As long as your power bank (power bank) capacity is less than 24,000mAh, you can take it on the plane.

In the regulations, the rated energy of the power bank does not exceed 100wh (watt-hour), what does it mean?

The standard set by the civil aviation department for power banks is "rated energy value (watt-hours)", and those less than 100 watt-hours can board the plane; Power banks with a rated energy value of 100 to 160 watt-hours are subject to the approval of the airline for boarding; Boarding is not permitted for those greater than 160 watt-hours.

As long as the rated energy value of the power bank meets the requirements, you can go through the procedures, which has nothing to do with whether the battery capacity is thousands or tens of thousands of milliamperes. "At present, the capacity of the power bank on the market is mostly between 3,000 and 15,000 mAh, and the "capacity" of individual power banks is 20,000 mAh. Most power banks are labelled with a voltage of between 3 and 4 volts.

According to the formula of the rated energy value, the rated energy value of the 20,000 mAh power bank is 20,000 mAh 1000 = 74h in the case of voltage volts, which is less than 100wh, in line with the regulations of the Civil Aviation Administration. "A 20,000 mAh power bank is a critical point, and basically a power bank below 20,000 mAh can be brought on the plane. If the power bank exceeds 20,000 mAh, it is necessary to calculate whether it exceeds 100wh, and if it exceeds it, it needs to be declared to the airline for approval.

For this issue, the Civil Aviation Administration has issued a special announcement. In August 2014, the Civil Aviation Administration of China issued an announcement specifically for civil aviation passengers to carry power banks, and when taking planes, they can only carry power banks with rated energy of less than 160wh. Anything that is not marked is prohibited.

(1) 5000mAh power bank can be brought on the plane.

2) According to the "Announcement on the Regulations on Civil Aviation Passengers Carrying "Power Banks" on Flights.

The rated energy of the power bank does not exceed 100wh, and no airline approval is required; Rated energy exceeding 100Wh but not exceeding 160Wh can only be carried with the approval of the airline, but each passenger is not allowed to carry more than two power banks.

3) Conversion method.

If the rated energy Wh (watt-hour) is not directly marked on the power bank, the rated energy of the power bank can be converted in the following way:

If the nominal voltage (V) and nominal capacity (Ah) of the power bank are known, the value of the rated energy can be obtained by calculation

wh= v x ah

Bring in data 5000mah 1000 = 5ah

Generally, the voltage of the power bank is 5V

So: 5V 5AH=5Wh

[Civil Aviation Administration's regulations on carrying power banks].

1. The rated energy is less than 100wh and can be brought on the plane.

The Civil Aviation Administration of China has made relevant regulations on carrying mobile power banks on the plane, power banks with rated energy of less than 100Wh can be brought on the plane, and power banks with rated energy between 100Wh and 160Wh need to be agreed by the airline before they can be brought on the plane. The power bank will not directly indicate the rated energy, only the capacity. Therefore, only after conversion, can we know how much capacity of power bank can be brought on the plane.

2. Formula conversion.

Take a power bank A as an example. A power bank will be marked on the capacity (capacity): rated energy = multiplied by 10000mAh = 37wh, less than 100wh, in line with the regulations of the Civil Aviation Administration, can be brought on the plane.

In the same way, the maximum output voltage of the general power bank is 5V, according to the formula conversion, capacity = rated energy divided by voltage, 100Wh divided by 5V is equal to 20,000 mAh, so the capacity of the power bank within 20,000 mAh can be brought on the plane.

A maximum of 2 power banks can be brought on board the aircraft, and the rated energy cannot be greater than 100Wh, which means that passengers can carry up to 2 power banks on the plane, and the total capacity does not exceed 20,000 mAh.

A 20,000 mAh power bank can be carried on an airplane, but it cannot be checked in and can only be carried with you.

The voltage of the 20000 mAh power bank is about 5 volts, and the rated energy of the power supply is about (20000 5 1000=) 100wh, which is lower than the specified 160wh, so it can be taken on the plane.

On August 8, 2014, the Civil Aviation Administration for the first time specifically for civil aviation passengers to carry "power bank" to take the plane issued an announcement, in the future, when taking the plane, only the rated energy within 160wh (watt hour) can be carried power bank, not marked value is prohibited to carry; Power banks are not allowed to be checked in.

At present, most of the common power banks on the market have a capacity of between 3,000 and 15,000 mAh, and individual power banks have a capacity of 20,000 mAh, and most of the power banks indicate a voltage between 3 and 5 volts. According to the formula of the rated energy value, the rated energy value of the 20,000 mAh power bank is 100wh under the condition of 5 volts, which is just the upper limit of the capacity that can be carried without the approval of the civil aviation company.

If the power bank is marked with voltage (V) and capacity ampere-hours (Ah), the value of the rated energy can be calculated by calculating the value of wh=V Ah.

If only milliamps ("ah") are marked on the power bank, you can divide this value by 1000 to get ampere-hours (ah).

As long as the rated energy value of the power bank meets the requirements, you can go through the procedures, and the battery capacity is tens of thousands of milliamperes.

According to Article 4 of the Regulations on the Administration of Transport of Dangerous Goods in Civil Aviation of China:

It is strictly forbidden to carry a power bank with a rated energy of more than 160Wh; It is strictly forbidden to carry a power bank that does not indicate the rated energy and fails to calculate the rated energy through other parameters marked.

20,000 mAh translates to 288Wh, which exceeds the maximum of 160Wh set by the airline. Therefore, a 20,000 mAh power bank cannot be carried on the plane.
