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.

Power Bank Airline Rules 2026: What Changed

2026 has brought the most significant changes to power bank airline rules in years. Following several high-profile lithium battery incidents in 2024-2025 -- most notably the Air Busan emergency landing -- airlines and regulators worldwide have tightened restrictions.

Major 2026 Changes by Region

Europe

Lufthansa Group (Lufthansa, SWISS, Austrian Airlines, Brussels Airlines, Eurowings) implemented a blanket ban on in-flight power bank use and charging effective January 2026. Power banks must remain switched off and stored in carry-on bags for the duration of the flight. This affects over 100 million passengers annually.

Other European carriers (Ryanair, easyJet, British Airways, Air France) continue to allow in-flight use under existing EASA guidelines, but industry observers expect more European airlines to follow Lufthansa's lead.

Asia-Pacific

The biggest wave of changes came from Asia-Pacific carriers:

Singapore Airlines banned in-flight power bank use

Cathay Pacific prohibited charging devices from power banks during flight

Thai Airways banned all in-flight power bank use

All South Korean airlines (Korean Air, Asiana, T'way, Jeju Air, Jin Air, Air Busan, Eastar Jet, Air Seoul) now require power banks to be visible during any use and immediately accessible for cabin crew inspection

South Korea's rules are directly tied to the Air Busan lithium battery fire in 2024 that forced an emergency evacuation. The Korean MOLIT (Ministry of Land, Infrastructure, and Transport) mandated the strictest power bank rules of any country.

Middle East

Emirates and flydubai now limit passengers to a maximum of 1 power bank per person regardless of capacity. Previously, the standard IATA allowance of 2+ units under 100Wh applied.

North America

Southwest Airlines introduced a requirement that power banks must be visible during use -- they cannot be concealed under blankets, in seat pockets, or between seats while charging a device. FAA and TSA rules remain unchanged at the federal level.

Rules That Haven't Changed

The fundamental rules remain the same across all airlines:

Under 100Wh: Allowed in carry-on, no approval needed

100-160Wh: Allowed with airline approval, max 2 units

Over 160Wh: Prohibited on passenger aircraft

Checked baggage: Power banks are NEVER allowed in checked bags

What to Expect Next

Aviation safety bodies including IATA, ICAO, and EASA are reviewing lithium battery transport regulations for possible updates in late 2026. Industry insiders suggest:

Possible reduction of the unrestricted threshold from 100Wh to 80Wh

Mandatory power-off for all portable lithium batteries during flight

Enhanced screening requirements at security checkpoints
