Power Bank Flight-Safe
Check capacity before you pack, then check the rules for your flight. A small power bank can still have restrictions on quantity, use and storage.
Manually verified:
Enter the battery rating and a whole-number quantity to check the rules.
Cabin baggage only. This checks capacity and quantity, not final acceptance. Confirm the label, route and airline rules below.
Published airline rules
This check assumes all entered banks have the same rating. For different banks, check each and count the total. Other large spare batteries can share an allowance: confirm the combination with the airline. Medical-device exceptions are outside this tool.

Common power bank sizes
Estimated at 3.7 V. Use the Wh printed on your power bank for a precise check.
| Capacity (mAh) | Wh (3.7 V) | General guidance |
|---|---|---|
| 5,000 mAh | 18.5 Wh | ≤ 100 Wh |
| 10,000 mAh | 37 Wh | ≤ 100 Wh |
| 20,000 mAh | 74 Wh | ≤ 100 Wh |
| 25,000 mAh | 92.5 Wh | ≤ 100 Wh |
| 26,800 mAh | 99.16 Wh | Check before you pack |
| 27,000 mAh | 99.9 Wh | Check before you pack |
| 30,000 mAh | 111 Wh | Check before you pack |
| 40,000 mAh | 148 Wh | Check before you pack |
| 50,000 mAh | 185 Wh | Outside these limits |
Close to a limit: check the printed Wh before you travel. Cabin baggage only. This checks capacity and quantity, not final acceptance. Confirm the label, route and airline rules below.
Published airline rules
Only the named operators are covered. Other subsidiaries and airlines require their own checks. Route coverage is limited; also check local airport and authority requirements.

Power bank rule updates
Flying from Singapore: The Two-Power-Bank Limit Explained
The Singapore departure rule applies to your bag, even when the operating airline is based elsewhere.
CAAS: new power bank safety restrictionsOfficial policy review
Why a 100 Wh Power Bank Limit Depends on Your Airline
Power-bank-specific rules can be stricter than an airline’s general spare-battery table.
American Airlines: portable chargers sectionGeneral guidance
ICAO limits power banks to 2, prohibits recharging them on board and recommends against charging devices with them. National implementation and airline restrictions differ. IATA’s operator guidance has a stricter capacity table; do not treat it as a single worldwide permission. Use the specific operator’s published policy.
ICAO [en] · IATA [en] · FAA PackSafe [en]
For mainland China domestic flights, CAAC requires a clear CCC / 3C mark and excludes recalled models or batches. This scope is not every international flight to China.
Before you pack
Can I fly with it?
Cabin baggage only. This checks capacity and quantity, not final acceptance. Confirm the label, route and airline rules below. Estimated at 3.7 V. Use the Wh printed on your power bank for a precise check.
Power banks per person
This check assumes all entered banks have the same rating. For different banks, check each and count the total. Other large spare batteries can share an allowance: confirm the combination with the airline. Medical-device exceptions are outside this tool.
Any mainland China domestic flight in your journey?
For mainland China domestic flights, CAAC requires a clear CCC / 3C mark and excludes recalled models or batches. This scope is not every international flight to China.
Charging a device
Only the named operators are covered. Other subsidiaries and airlines require their own checks. Route coverage is limited; also check local airport and authority requirements.
Printed rating (Wh)
Keep the capacity label readable. If it is missing or unclear, ask the airline before travel; this calculator cannot certify an unlabelled bank.
Nominal battery voltage (V)
Use nominal battery voltage, not USB output such as a fast charger’s advertised voltage. If it is unknown, consult the manufacturer rather than guessing.
Connecting flights
Every operating airline and relevant departure authority can set conditions. A bank accepted on one flight may not be accepted on the next.
Gate-checked bags
Before a cabin bag is taken into the hold at the gate, remove the power bank and keep it protected in the cabin.
Damaged or recalled banks
Do not travel with damaged, swollen or recalled banks. Check the manufacturer’s recall information for your model and batch.
