Can your power bank fly?
Convert the label to watt-hours, check the airline limit, and see exactly where the bank must be stored and whether you can use it onboard.
Within the published limit
74.0Wh
Under U.S. FAA baseline
- 74.0Wh is within the common 100Wh capacity limit.
- No fixed limit under 100Wh for personal use; larger spares are limited to two
- Carry-on only; protect terminals and keep the bank accessible
- FAA leaves stricter quantity, storage, and use rules to the airline

Capacity is only the first check. Power banks are carry-on only, damaged or recalled units cannot fly, and the airline may impose a stricter count, storage location, or onboard-use rule. A printed Wh rating beats a calculated estimate.

Power-bank rules by airline
We publish only rules we can trace to the regulator or operating airline. Rows show the stricter power-bank-specific rule when it differs from general spare-battery guidance.

What changed in 2026
ICAO separated power banks from ordinary spare batteries, limited passengers to two, and prohibited recharging the bank onboard. IATA recommends that passengers also avoid using a bank to charge another device. Adoption and legal enforceability vary by state, so the operating carrier's published rule remains decisive.
How this dataset is maintained
Every row links to a first-party policy and carries a verification date. We record capacity, count, storage, and onboard-use rules separately because airlines often use the word "charging" for two different actions. Corrections can be sent through the contact page.
A high-capacity bank with room below 100Wh
The Anker 737 is labeled 86.4Wh, leaving 13.6Wh of capacity headroom while delivering enough USB-C output for most laptops. Airline quantity and onboard-use rules still apply. Compare all travel power-bank picks →

The Anker 737 combines a printed 86.4Wh rating, up to 140W USB-C PD 3.1 output, three ports, and a real-time smart display. Its capacity sits below the common 100Wh threshold, while airline count, storage, and onboard-use rules still apply.
- Smart digital display shows exact battery percentage, input/output wattage in real time
- 140W PD 3.1 output is fast enough for most laptops at full speed
- At 1.39 lb it is noticeably heavier than phone-only banks, not a featherlight day-trip option

Frequently asked questions
Can a power bank go in checked luggage?
No. Power banks are treated as spare lithium batteries and must stay in the aircraft cabin. Remove them before a carry-on bag is gate checked, protect the terminals, and keep them accessible.
Is a 20,000mAh power bank allowed on a plane?
Usually. At a common 3.7V nominal voltage, 20,000mAh equals 74Wh, below the common 100Wh limit. The printed Wh rating and your airline's quantity and storage rules still control.
Is a 27,000mAh power bank under 100Wh?
At 3.7V, 27,000mAh calculates to 99.9Wh. That is extremely close to the limit, so use the manufacturer's printed Wh rating instead of relying on rounded math.
Can I bring a 30,000mAh power bank?
A 30,000mAh bank at 3.7V is about 111Wh. Some FAA and 2026 ICAO pathways allow 100-160Wh with advance airline approval, but several carriers prohibit power banks above 100Wh entirely.
Can I use a power bank during the flight?
It depends on the carrier. The 2026 ICAO change prohibits recharging the power bank onboard and IATA recommends not using it to charge another device. Some airlines permit visible use; Emirates prohibits both uses.
How many power banks can I bring?
The 2026 ICAO baseline limits passengers to two. The FAA does not set a fixed count below 100Wh for personal use, but airlines can be stricter: Southwest permits one, while American and Qatar permit two.
