What is the largest power bank that can be carried through airport security?

The maximum capacity of an external battery that can pass the security check is 16,000 mAh.

Guidance for passengers carrying lithium-ion batteries on board

According to the civil aviation industry standard of the People's Republic of China "Specifications of air transportation of lithium batteries” (MH/T1020-2009 ) and “Passengers and crew regarding the carriage of lithium batteries”, “Specifications for the carriage of dangerous goods by air” (MH/T1030-2010) and other relevant regulatory documents. Passengers carrying lithium-ion batteries on civil aircraft should pay attention to the following points. :

1. The energy rating of transported lithium-ion batteries is not allowed if it exceeds 160 Wh, it must be transported via dangerous goods procedures.

2. Equipment containing lithium-ion batteries (such as laptops, cameraso, camcorders, etc.) must be carried in accordance with the following rules:

(1) May be placed in checked baggage and carried in carry-on baggage.

(2) Measures must be taken to prevent accidental starting.

(3) The rated energy of lithium-ion batteries should not exceed 100 Wh.

(4) Lithium-ion batteries with a rated energy between 100 Wh (exclusive) and 160 Wh (inclusive) must be approved by the operator (airline).

3. Spare lithium-ion batteries must be carried according to the following rules:

(1) They may only be carried in carry-on baggage.

(2) Individual batteries must be protected against short circuits. Replacement batteries can be placed in their original retail packaging or the electrodes can be insulated - for example, by taping the exposed electrodes,placing the battery. Packed separately in plastic belts or protective bags

(3) The rated energy of a single lithium-ion battery should not exceed 100Wh.

(4) With operator (airline) approval, spare lithium-ion batteries with a rated energy of 100 Wh (exclusive) to 160 Wh (inclusive) may be carried , but no more than 2 batteries can be carried. be worn.

Can you take 10,000 mAh on a plane? 1 mA = how many WH?

1. A 10,000 mAh external battery can be carried on board the aircraft

2 In accordance with the ICAO “Technical Instructions for the Safety of the Transport of Dangerous Goods by Air” (2011-2012). Edition), portable electronic devices (watches, calculators, cameras, mobile phones, laptops, camcorders, etc.) containing lithium or lithium-ion cells or batteries intended for personal usePassengers or crew members must be carried on board as carry-on baggage. luggage and lithium metal The lithium content of the battery should not exceed 2 grams, and the rated energy value of the lithium-ion battery should not exceed 100 Wh (watt hours). If the battery exceeds 100 Wh but does not exceed 160 Wh, it can). be installed on the equipment in checked baggage or carry-on baggage with the agreement of the airline, lithium batteries exceeding 160Wh are strictly prohibited.

3. "Wh" is the power, that is, the power of the battery (it is a quantity directly proportional to voltage, current and time). Parameter called "mAh", mAh (milliamp hour) is the basic unit of battery capacity. Usually, the battery capacity of mobile phones and other portable devices is expressed in mAh, while electric vehicles, electric vehicles, andvs. are expressed in larger Ah (ampere-hours), i.e. 1 Ah = 1000 mAh. When current intensity is measured in milliamperes (mA) and time in hours (h), the product of the two is milliampere-hour (mAh), that is, a cell phone battery d A capacity of 1000 mAh is used. a current of 1000 mA. Under high current, it can provide continuous power output for 1 hour. We generally use to say milliamps for short.

4. The general power of a power bank is 5V, so 5V × 10,000mAh (10Ah) = 50Wh, which is much lower than current civil aviation regulations

10000mAh power bank can be used for air travel. Milliamps and watt hours cannot be directly converted and a voltage is required. For example, if the voltage of a 10,000 mAh external battery is 5 V, then the rated energy of the batteryexternal power is 50 Wh. Calculation: (10,000 mAh ÷ 1,000) x 5 V = 50 Wh, then 1 mA is equal to 0.005 Wh.

According to the “Announcement on Regulations for Civil Aviation Passengers Carrying “Power Banks” When Boarding”, passengers carrying power banks on board must comply with the following regulations:

1. The power bank must be intended for the passenger's personal use.

2. External batteries can only be carried in carry-on baggage or with you, and it is strictly prohibited to carry them in checked baggage.

3. External batteries rated at less than 100 Wh do not require airline approval; external batteries with a power rating greater than 100 Wh but not more than 160 Wh may only be carried with airline approval. , but each passenger is not allowed to transcarry more than two external batteries.

4. It is strictly prohibited to carry a power bank with a rated energy above 160 Wh. It is strictly prohibited to carry a power bank that does not indicate the rated energy and cannot calculate the rated energy using other brands; settings.

5. The power bank should not be used to charge electronic devices during flight. For external batteries with a start switch, the external battery must always be turned off during flight.

Detailed information

How to determine the rated energy of lithium batteries and external batteries

If there is no has no direct label on the lithium battery or power bank Rated energy Wh (watt hours), the rated energy of lithium batteries and power banks can be converted as follows:

(1 ) If the tNominal voltage (V) and nominal voltage of lithium batteries and power banks are known. Weighing capacity (Ah), the nominal energy value can be obtained by calculation: Wh= V x Ah. (Rated voltage and rated capacity are usually marked on lithium batteries and power banks)

(2) If only milliampere-hours (mAh) are marked on lithium batteries and power banks external, the value can be divided into ampere-hours (Ah) are obtained as 1000.

For example: the rated voltage of lithium battery and power bank is 3.7V , the nominal capacity is 760 mAh and its nominal energy is:

760 mAh ÷ 1000 = 0.76 Ah.

3.7 V × 0.76 Ah = 2.9 Wh.
