Tldr:
Check with your airline before traveling.
It seems like the most practical way to approach this as an airline passenger is to place your battery into superposition where the battery can be both within arm's reach, but also stowed away. Warning, do not observer or interact with the battery while the flight is in the air lest you collapse the waveform and lose superposition.
That seems overly complicated. How about just bringing an extra arm in the carry-on?
Easy. You put it in your backpack under the seat in front of you with a long cable. Now no one knows it exists, but your bag is within arms reach so the battery is too
lest you collapse the waveform and lose superposition.
But then I could reach my destination instantly!
Just an arm and leave it with the battery, problem solved.
and check if your airline allow you to use power bank during the flight and this is quite problematic for someone who want to work or play games during long flight. For now, only Cathay allows you to use it.
And the article only refers to airlines in east and southeast Asia.
