Quick answer: Airlines generally allow power banks under 100Wh in cabin baggage and do not allow them in checked luggage. A 10000mAh power bank is roughly 37Wh, so it is normally fine for carry-on, but you should always confirm with your airline before travel. The Befenb Y33 10000mAh (Rs 3,300 at Horus.com.pk) is listed as airline approved for iPhone and Android.
How to convert mAh to Wh
Watt-hours = mAh × 3.7V ÷ 1000. Most power banks use 3.7V cells, so:
| Capacity | Approximate Wh | Usually allowed in cabin? |
|---|---|---|
| 5,000mAh | About 18.5Wh | Yes |
| 10,000mAh | About 37Wh | Yes |
| 20,000mAh | About 74Wh | Yes, usually |
| 27,000mAh and above | About 100Wh and above | Often needs airline approval or is not allowed |
Practical airline tips
- Keep power banks in your carry-on bag, never in checked luggage.
- Look for the Wh or mAh rating printed on the power bank.
- Avoid using it during take-off and landing, and follow crew instructions.
- Rules differ by airline and country, so check your airline's page before you travel.
