Wondering if a 20000mAh power bank is allowed on airplanes? Discover airline battery policies, safety tips, and travel-friendly product recommendations in this expert guide.

1. Quick Answer
Yes, a 20000mAh power bank is allowed on most flights, as long as it meets international aviation safety standards — typically below 100Wh.
However, it must be packed in your carry-on luggage, not in checked baggage, and should be properly labeled with capacity information.
2. Why Airlines Regulate Power Banks
Power banks are classified as portable lithium-ion batteries. These pose a fire risk if:
Damaged or short-circuited
Overcharged
Packed with conductive metal objects (like coins or keys)
Airlines and aviation authorities (e.g. IATA, FAA, EASA) implement restrictions to ensure safety during flight.
3. Understanding Power Bank Limits (mAh vs Wh)
Power banks are often marketed by mAh (milliampere-hour), but aviation rules regulate them by Wh (watt-hours).
Wh = (mAh × Voltage) ÷ 1000
Wh = (20000 × 3.7) ÷ 1000 = 74Wh
✅ Under the 100Wh limit, so it’s generally allowed on flights without special approval.
4. Is a 20000mAh Power Bank Allowed on Flights?
Yes, here are the official guidelines:
| Capacity | Airline Policy |
|---|---|
| ≤ 100Wh (up to ~27000mAh) | ✅ Allowed in carry-on, no approval needed |
| 100Wh–160Wh | ⚠️ Allowed in carry-on with airline approval |
| > 160Wh | ❌ Not allowed |
Therefore, 20000mAh (≈ 74Wh) is well within the limit.
5. Airline and Country-Specific Rules
Most major airlines follow IATA guidelines, but there may be slight variations:
United States (FAA/TSA):
≤100Wh: Allowed in carry-on
Must have visible capacity labeling
EU (EASA):
Similar to FAA, but stricter with unbranded products
China:
Max 2 power banks ≤100Wh per passenger
Must be labeled in Chinese or English
Popular Airlines:
Emirates: Allowed if under 100Wh
Lufthansa: Must be in original packaging or with terminals protected
American Airlines: 100Wh limit, no check-in
Singapore Airlines: Up to 100Wh, up to 2 units
Pro tip: Always check your airline’s specific policies before travel.
6. Carry-On vs Checked Luggage Rules <a name=”carry-on-vs-checked”></a>
✅ Carry-On:
Yes, mandatory for all power banks
Easy to monitor in case of thermal issues
❌ Checked Baggage:
Strictly prohibited due to fire risk
Always place your 20000mAh power bank in your backpack, purse, or hand-carry luggage.
7. Travel Tips for Power Bank Users
To ensure smooth travel with your power bank:
✅ Choose a branded, certified power bank (CE, RoHS, UL)
✅ Look for models with visible capacity (Wh or mAh) markings
✅ Avoid power banks with exposed terminals
✅ Carry the original packaging if possible
✅ Limit usage during takeoff and landing
❌ Don’t daisy-chain multiple devices
