Carry-On-Safe High-Capacity Power Banks
9 of 19 power banks combine 20,000mAh+ claimed capacity with a rated Wh at or under the 100Wh carry-on limit.
The sweet spot for travelers: at least 20,000mAh of claimed capacity while staying at or under the 100Wh US carry-on limit (most airlines' unrestricted allowance). One row in the full table (Anker's 250W Prime bank) claims more capacity than this but computes to just over 100Wh and is excluded here.
