Choosing a power bank

Power banks fly in carry-on bags only. The FAA allows lithium-ion batteries of up to 100 watt-hours each, and up to two spares of 101–160 Wh with the airline’s approval; airlines may set lower limits.

Listings give capacity in milliamp-hours. Watt-hours are mAh × the cell voltage ÷ 1,000, so a 20,000 mAh bank at 3.7 V is 74 Wh, and a 27,000 mAh one is just under 100 Wh.
