FAQ
Can I carry a 20000mAh power bank on Singapore Airlines?
In most cases yes, because 20000mAh at 3.7V is roughly 74Wh, which is below the 100Wh threshold. It should stay in carry-on baggage.
What if my Singapore Airlines battery is over 100Wh?
Batteries between 100Wh and 160Wh often need airline approval before travel. Anything above 160Wh is generally not accepted.
Before you fly
- Match the Wh result on this page against the exact number printed on your battery if the label is available.
- Protect terminals, avoid loose batteries in checked bags, and switch devices off before checking them in.
- Use the official airline source again right before departure because airport and airline rules can change without notice.
