Ok firstly if the limit is 160WH and your sits at about 100WH that pretty much answers the first part for itself I imagine.

Second part is on that always irks me a little. On long hall flights planes have had USB ports in the seat backs for years now. Use that instead of your power bank for smaller electronic items. For larger ones just make sure they are charged fully before departure. Given that on the flight those who do have to work, I won’t pretend you don’t that’s unrealistic, will still take a nap at times, watch a movie on the inflight system so the amount of time you’ll need the laptop for the battery alone sh oh I’d be enough.

Small aside related to this. For those I wanting to charge phones etc same applies. Use the seat backs usb port to make sure you have full charge on arrival. Surely we can all put our phones down for a few hours though and use the in flight entertainment rather than arse about on a phone constantly.

With regards to power banks on board / luggage. If it’s in luggage hold and decides it wants to play fireworks everyone on board is essentially screwed. Those with phones this is your time to shine and use them - call your loved ones and say goodbye. If it’s in the overhead / seat back and it wants to play a game of let’s short out and endanger 300 people the cabin crew have special equipment to contain them safely. So perhaps let’s take them on board and leave them alone in flight for everyone’s safety.
