In today's society, mobile power has become an indispensable part of people's daily life. However, when flying or other means of public transport, we often encounter security issues. So, if we have a 20,000 mAh power bank on hand, can we take it through security?
First of all, we need to understand the basic rules of security. According to the International Air Transport Association (IATA), passengers must not carry batteries with a rated energy of more than 100wh (watt-hours). This means that if our power bank capacity exceeds this limit, then we will not be able to carry it on the plane.
However, according to some real-world tests, the energy rating of a 20,000 mAh power bank is usually around 60Wh, which is well below the 100Wh limit. Therefore, theoretically, a 20,000 mAh power bank can be carried on an airplane.
However, in practice, we also need to pay attention to some details. First of all, we need to make sure that our power bank meets aviation safety standards, such as the rated energy limit of 100Wh must not be exceeded. Secondly, we need to make sure that our power bank does not have any dangerous goods or contraband, such as lithium batteries, etc. Finally, we need to carry the power bank in our hand baggage after security in order to be screened.
In short, a 20,000 mAh power bank can be carried on board, but we need to make sure that it meets aviation safety standards and that there are no dangerous goods or contraband. At the same time, we are required to carry the power bank in your hand baggage after the security check in order to be screened.
