Can I bring a laptop power bank on a plane?

Yes, as long as it's under 100Wh (which all three picks are). Power banks must go in your carry-on, never checked luggage. The Anker 737 at 86.4Wh and the INIU at ~90Wh are both safely under the limit.

How many laptop charges will I get from a power bank?

Roughly 50-80% of a MacBook Air charge from a 20,000mAh bank, or 60-90% from a 25,000mAh bank. Conversion losses mean you never get the full rated capacity. Plan for about 60% efficiency in real-world use.
