How do I find the capacity of my power bank?

Flip your power bank over and look for a number followed by 'mAh' (like 10000mAh or 20000mAh). It's usually on a sticker on the bottom or back. If you can't find it, check the original box or the manufacturer's website.

What does mAh and Wh mean?

They're just different ways to measure how much energy your power bank stores. Think of mAh as the size of the fuel tank, and Wh as how much fuel is actually in it. Airlines care about Wh -- but don't worry, our tool converts it for you automatically.

Can I put my power bank in my checked suitcase?

No, never. This is one rule that applies everywhere in the world, on every airline. Power banks must go in your carry-on bag -- the one you take into the cabin with you. If security finds one in your checked bag, they'll remove it and your bag could be delayed.

How many power banks can I bring?

For regular-sized power banks (under 100 Wh), most airlines let you carry several. For larger ones (100-160 Wh), you're usually limited to 2 and need airline permission. Some airlines like Emirates only allow 1 power bank per person, regardless of size.

Can I use or charge my power bank during the flight?

It depends on your airline. Many airlines (including Lufthansa, Singapore Airlines, and all South Korean carriers) now ban using or charging power banks during the flight. Others allow it but ask you to keep it visible. Check your specific airline using the tool above.

What if my power bank doesn't have a label?

You might have trouble at security. Many airports -- especially in China and India -- will confiscate power banks without readable labels. If your label has worn off, try looking up the specs online and bringing a printout or screenshot as backup.

What if my power bank is damaged or swollen?

Do not bring it on a plane. A swollen or damaged power bank is a fire risk. Dispose of it safely at a battery recycling point and get a replacement before your trip.

What are the rules for flights in China?

China has extra rules: your power bank needs a readable capacity label and a 3C certification mark (for Chinese-made batteries). You also can't use or charge it during the flight. Power banks without proper markings may be taken away at security.
