These are my favorite two Powerbanks that are within the TSA limits.
Please note they must be “carried on” and not checked it.
ANKER Quoted:

the majority of Anker power banks are within the 27,027mAh limitation. For example, you are able to bring the PowerCore III Elite 25600 60W (735 Power Bank) on a flight. The capacity of this PowerCore is 25,600mAh/94.72Wh and it is labeled on the bottom of the battery. However, please make sure the power bank is in your carry-on luggage since power banks cannot be placed in your checked luggage.
