Short answer: Under 100 Wh is the normal 2026 passenger power-bank band. The old 100-160 Wh approval concept is now more fragile for power banks: check the airline and route before relying on it. Over 160 Wh is prohibited on passenger aircraft.

The 100 Wh line is the most important everyday threshold because many consumer power banks are designed to sit below it.

The 160 Wh line is not a free pass. It is an upper boundary in some lithium-battery approval frameworks, not automatic permission for a power bank. Travelers may need airline approval, quantity limits can apply, and local rules can still be stricter.

Anything over 160 Wh should be treated as banned for passenger travel. If a product is close to a threshold, use manufacturer-stated Wh or clear label evidence instead of guessing from marketing capacity.

Rule summary

<= 100 Wh
Usually allowed in carry-on without prior airline approval.
100-160 Wh
Airline- and trip-sensitive for power banks under 2026 guidance.
> 160 Wh
Prohibited on passenger aircraft.
Always
Standalone power banks are carry-on only.

FAQ

Is 100 Wh the same as 27,000 mAh?

Roughly. At 3.7 V, 27,000 mAh is about 99.9 Wh, which is why many large travel power banks cluster near that capacity.

Can a 120 Wh power bank fly?

It needs airline- and route-specific review. Do not assume a 120 Wh power bank can travel just because an older approval band exists.

Can a 200 Wh power bank fly?

No. Over 160 Wh should be treated as prohibited for passenger aircraft.

Which number should I trust, mAh or Wh?

Trust the printed or manufacturer-stated Wh when available. mAh needs voltage to become meaningful for aviation limits.
