Can I bring a power bank on an international flight?

Question

Accepted Answer

Yes, in carry-on only. Under 100Wh: no restrictions. 100-160Wh: airline approval required (usually just ask at check-in). Over 160Wh: not allowed on any flight. The 100Wh limit equals roughly 27,000mAh. Most travel power banks are designed to stay just under this limit.
