There is no single allowance for every airline. Several airlines allow two power banks, while Southwest, Emirates and Etihad limit passengers to one. Check the airline page for the current quantity and Wh limit.
Count the devices, then check each label
Two 10,000 mAh power banks are two devices, not one 20,000 mAh device. Each must meet the capacity rule, and together they must meet the quantity rule.
Connections can change the allowance
If one operating airline permits two and the next permits one, carrying two does not meet the rules for your whole trip. Plan for the most restrictive leg.
