Short answer: Yes. A power bank must travel in carry-on baggage, not checked baggage. In 2026, also plan for no more than two lithium-ion power banks, each not exceeding 100 Wh, and keep them accessible so crew can respond if one overheats.
A power bank is treated as a spare lithium-ion battery, not as a battery installed inside a device. Spare lithium batteries belong in the cabin because smoke, heat, or fire can be noticed and handled quickly.
The carry-on rule applies even to small power banks. A 5,000 mAh or 10,000 mAh charger should still not be placed in checked baggage, and the 2026 quantity and in-flight charging rules apply separately.
Pack the power bank where you can reach it, keep the label readable, and do not hide it deep inside an overhead bag if your airline or crew asks passengers to keep power banks accessible.

Can a small power bank go in checked baggage?
No. The carry-on-only rule applies to standalone power banks regardless of whether the capacity is low.
Why does carry-on matter?
Lithium-ion batteries can overheat. In the cabin, crew can identify and respond to a battery incident; in the cargo hold, response is much harder.
Does carry-on mean automatically allowed?
No. Carry-on is required, but capacity, quantity, label evidence, route overlays, airline rules, and recall status can still change the final answer.
