Hi Roslaind, as you mentioned you would like to use the power bank during your flight journey, generally speaking ,if you are not a heavy game player, 2 full charging cycle would definitely meet your requirement. Around 15000 mAh capacity is quite sufficient for your charging and no worries about the security check, I recommend https://www.easyacc.com/en/919-easyacc-megacharge-16750mah-doubin-usb-c-power-bank.html

There is a lot wrong in this article. It is NOT good to fully deplete a lithium battery not is it good to fully charge. the best way to maintain lithium battery life is to keep between 25 and 80 percent battery at all times. There are many applications that can help with this. This article refers to older batteries which have memories.
