Computers can be brought directly onto the plane, but make sure there is no Internet connection on the computer; if the laptop battery is for personal use and the lithium-ion battery is used, its rated energy value must not exceed 100wh, which means the capacity is 20,000 mAh.
According to the "Civil Aviation Clear Telegram [2011] No. 1888 "Notice on Strengthening the Safe Air Transport Management of Lithium Batteries in Passenger Baggage"":
ICAO's "Technical Instructions for the Safe Transport of Dangerous Goods by Air" (2011-2012 edition) stipulates that passengers or crew members must use portable electronic devices containing lithium or lithium-ion cells or batteries for personal use (watches, computers, etc.) devices, cameras, mobile phones, laptops, camcorders, etc.) should be carried on board as carry-on baggage.
And the lithium content of lithium metal batteries must not exceed 2 grams, and the rated energy value of lithium-ion batteries must not exceed 100wh (watt hours), which is what we usually call a capacity of 20,000 mAh.
According to the latest regulations of airlines, electronic products can be brought on the plane, so laptops can be brought on the plane and can also be used on the plane. We need to pay attention to the following things when taking a computer on a plane.
The first thing is to take the computer out of the suitcase in advance, which can speed up the security check.
Secondly, do not place other external products on the computer, such as CDs, U disks, etc., to avoid unnecessary trouble.
Then if you are carrying more than 2 computers, you must remove the batteries in advance and store and pack them separately.
Generally speaking, various entertainment functions on airplanes are now relatively complete, and you can watch movies and listen to music. Therefore, try to keep the computer turned off and do not connect to the Internet to avoid unnecessary trouble.
Notes
Safety is no small matter. Please strictly abide by national regulations when bringing electronic products on board.
