Travel to Canada at the end of this month and take an Air Canada flight in Shanghai. I want to ask if I can bring a laptop and a charging treasure.

Within the rated capacity, the charging treasure and laptop can be taken on the plane at the same time.

According to the Notice on Strengthening the Safe Air Transport of Lithium Batteries in Passengers' Luggage issued by the Civil Aviation Administration, lithium battery products such as charging treasure cannot be checked, but can only be carried with you, and the lithium content of lithium metal batteries should not exceed 2g, and the rated energy value of lithium ion batteries should not exceed 100Wh (watt-hour), and only two batteries can be carried with you. Those exceeding 100Wh but not exceeding 160Wh may be carried with the approval of airlines, and lithium batteries exceeding 160Wh are strictly prohibited. At the same time, charging treasures without relevant signs cannot be brought on the plane. Don't use charging treasure to charge electronic equipment in flight. Charging treasure with start switch should be turned off all the time during the flight.

How to judge whether the charging treasure energy exceeds the standard?

If the rated energy Wh is not directly marked on the charging treasure, the rated energy of the charging treasure can be converted in the following ways: the nominal voltage (V) and the nominal capacity (Ah) of the charging treasure are usually marked on the charging treasure, and the value of the rated energy can be obtained through calculation: Wh = V×Ah；; If the charging treasure is only marked with mAh, you can divide this value by 1000 to get (ah).
