Good quality Power bank with fast charging for family.

Basically more power equals more lithium ions. Flights are pressurized environments. Do changes of ignition, explosions are higher

And what about the newer battery tech (Silicon carbon) that's enabling higher capacity batteries in mobiles these days? If those start showing up in laptops / powerbanks, they'll have massive capacities soon, like a 50000 mah powerbank or a 200-250wh laptop, what would be done in such a case?

As per AI:
1. Airline Approval Required
Power banks with a capacity between 100 Wh and 160 Wh are only allowed in carry-on baggage if you obtain explicit approval from the airline before your flight.
This approval process often requires you to provide documentation showing the power bank’s watt-hour rating, and sometimes safety certifications or manufacturer specifications
Only 2 units allowed.

2. Above 160 Wh Prohibited
Any power bank above 160 Wh is strictly prohibited on all passenger flights, regardless of approval or documentation.

Less then or equal to 100 Wh do not require any approval, any quantities can be carried
