Why can a power bank be brought on a plane but cannot be used?

 Samsung has introduced two new power banks for the Indian market, one with a capacity of 10,000 mAh and one with a capacity of 20,000 mAh.

Both power banks are only offered in one color, beige. They are listed on Samsung 's official online store page in India, but currently only the 10,000 mAh model is on sale.

The 10,000 mAh version has a maximum capacity of 25W and costs 41 USD (about 1 million VND). The charger measures 148 x 72 x 16.4 mm and weighs 222g. It can charge up to 2 devices via 2 USB-C ports and can also wirelessly charge a third device.

When using the function to charge 2 devices simultaneously, the charger's maximum wireless charging power for each device is only 7.5W. If you use the wired charging function of 2 devices simultaneously, the power received for each device is 10W. This is not surprising because 25W charging is only available when the user is charging a device.

Meanwhile, the 20,000 mAh version does not support wireless charging. This charger provides up to 45W of power if only charging one device, but the power bank can charge up to 3 devices at the same time via 3 USB-C ports, however the power received is for each device. is only 15W.

Many people may wonder why using a power bank on flights is not possible.

A few days ago, on a flight from Boracay Island (Philippines) to Shanghai (China), a power bank carried by a passenger exploded and the cabin was immediately filled with smoke. This caused the plane to make an emergency landing in Hong Kong. Airport fire and emergency rescue forces were quickly on the scene to resolve the incident. Luckily no one was injured.

According to the regulations of the Civil Aviation Authority of many countries, power banks whose rated capacity does not exceed a specific threshold can be brought on board without airline approval. At the same time, to some extent it will be carried on the plane and requires airline approval.

But whether brought on the plane or not, passengers are required not to use power banks to charge electronic devices such as mobile phones, tablets, etc. during the flight.

So why are power banks brought on board but not used on the plane? This is because the aircraft cabin is a high-pressure environment. During takeoff and landing, the pressure in the cabin changes, decreasing from 1ATM before takeoff to about 0.6ATM during the journey. fly, then ascend again upon landing.

In this environment, the lithium battery in the power bank will change. If you use a backup charger at this time, it will easily cause heat, increase the possibility of spontaneous combustion and dangerous flight safety. In case the power bank explodes or catches fire on the plane, users should seek help from the crew as soon as possible because the plane is equipped with fire extinguishers that can effectively handle battery fires. lithium, and staff will be equipped with the knowledge to handle emergencies in the best possible way.
