A lithium power bank belongs in the cabin, not in checked baggage. That is only the first check: you also need to establish its watt-hour rating, the permitted number of units, labelling requirements, cabin storage rules and whether you may use it during the flight.

Sources were checked on **9 October 2026**. This guide covers an ordinary personal power bank. Medical equipment batteries, mobility aids and batteries built into smart luggage require separate checks.

## Carrying a power bank does not mean you can use it

Separate three questions when reading the airline’s policy:

1. May I bring this power bank into the cabin?
2. May I use it to charge my phone?
3. May I recharge the power bank from an aircraft socket or USB port?

An allowance to carry the device does not answer the other two questions.

ICAO’s changes approved on 27 March 2026 limit passengers to two power banks and prohibit recharging the power bank on board. They recommend against using it to charge another device; an airline may impose an outright ban. [ICAO’s explanation](https://www.icao.int/filebrowser/download/92841?fid=92841&ref=roadme.io).

Charge your phone before boarding and save tickets, your accommodation address and arrival instructions for access without a connection. Avoid making your travel arrangements depend on being able to use a power bank in flight.

## Read the watt-hour rating on the device

Watt-hours, or Wh, describe stored energy. A figure in watts, such as “65 W”, describes power and cannot replace Wh. A capacity in milliamp-hours, or mAh, needs the corresponding battery voltage for conversion.

When the manufacturer supplies both figures:

**Wh = mAh × V ÷ 1,000**

Illustrative calculation: **20,000 mAh × 3.7 V ÷ 1,000 = 74 Wh**. That result applies to the stated voltage, not every 20,000 mAh power bank.

Use the nominal battery voltage associated with that capacity, not the USB output voltage. [Anker’s conversion guide](https://www.anker.com/uk/blogs/power-banks/mah-to-wh?ref=roadme.io)explains the distinction.

Start with the factory Wh marking. If it is missing or worn away, ask the carrier which evidence it accepts. A printed specification does not guarantee acceptance in place of mandatory labelling, and a handwritten sticker is not a substitute.

## Identify the capacity category, then check acceptance

The table below tells you what to investigate. It does not grant permission to travel with a device.

| Rating of one lithium-ion battery        | What to check                                                                               |
| ---------------------------------------- | ------------------------------------------------------------------------------------------- |
| Up to and including 100 Wh               | Unit count, labelling, route restrictions and onboard use                                   |
| Above 100 Wh, up to and including 160 Wh | Whether the airline accepts power banks in this category and how to obtain advance approval |
| Above 160 Wh                             | Not permitted as an ordinary power bank in passenger cabin or checked baggage               |

The [UK CAA guidance](https://www.caa.co.uk/commercial-industry/airlines/dangerous-goods/changes-to-rules-on-the-carriage-of-lithium-cellsbatteries-and-power-banks/?ref=roadme.io) describes operator approval for the above-100-to-160 Wh category. The [FAA passenger battery guidance](https://www.faa.gov/hazmat/packsafe/airline-passengers-and-batteries?ref=roadme.io) also states the upper passenger-baggage limit. Neither reference overrides stricter conditions imposed for your flight.

IATA’s 2026 guidance excludes approval for power banks above 100 Wh and up to 160 Wh from the DGR edition effective on 1 January 2027\. Recheck the rules before travelling in 2027\. [IATA guidance dated 31 March 2026](https://www.iata.org/contentassets/90f8038b0eea42069554b2f4530f49ea/guidance-to-operators---power-banks.pdf?ref=roadme.io).

## Find the operating carrier for every flight

Your booking should identify who operates each sector. With a codeshare, that may differ from the airline selling the ticket.

Look on the official website for Dangerous goods, Lithium batteries or Power banks. A page about cabin bag dimensions is not enough.

Record:

- the Wh limit per unit;
- the number permitted per passenger;
- required labelling;
- any approval process;
- where the device must be kept in the cabin;
- rules for charging a phone and recharging the bank itself.

For example, [Emirates’ announcement of rules effective from 1 October 2025](https://www.emirates.com/media-centre/emirates-makes-changes-to-safety-rules-for-customer-usage-of-power-banks-onboard/?ref=roadme.io) specifies one power bank, prohibits both charging activities and excludes overhead-bin storage. This illustrates carrier restrictions; consult the current passenger policy before your own journey.

Do not transfer permission from the first flight to a connection or return flight. If the wording is unclear, send customer support the model, photographs of its markings, Wh rating, unit count and relevant flight details. Obtain an answer before leaving.

## Check airport and national requirements

Review the security-screening rules along the route, especially if a connection involves a domestic flight or another screening checkpoint.

For example, Shanghai Airports’ notice for domestic flights in China prohibits power banks without a 3C certification marking, with unclear 3C markings or belonging to recalled models or batches. Meeting a Wh limit does not replace that check. The notice concerns domestic flights; establish the requirements for your international sector separately.

Make a short trip record:

| Part of the journey | Record                                                      |
| ------------------- | ----------------------------------------------------------- |
| Outbound flight     | Operating carrier, Wh limit, unit count and approval        |
| Connection          | Next carrier and any repeat-screening requirements          |
| Return flight       | Restrictions applicable on the return date                  |
| Cabin use           | Storage location and whether phone charging is allowed      |
| Evidence            | Official link, checking date and support response if needed |

If the device fails a required condition, choose a suitable alternative or leave it at home.

## Pack it for protection and quick removal

![](https://roadme.io/blog/content/images/2026/10/file23-1.webp)

Use a suitable individual protective pouch to protect the power bank against damage and short circuits; keep it separate from keys and coins. Protection requirements appear in IATA’s operator guidance.

Keep it accessible within a permitted cabin bag, with the factory marking available for inspection. Once on board, follow the carrier’s storage instructions.

If your cabin bag is taken at the gate for carriage in the hold, **remove the power bank before handing over the bag and keep it in the cabin**. The FAA’s lithium battery guidance explicitly covers this situation. For the bag itself, see the [carry-on-only packing guide](https://roadme.io/blog/carry-on-only-how-to-pack-without-excess-weight/).

Do not travel with a swollen or damaged power bank; check manufacturer recalls. If it becomes unusually hot, smokes or is damaged at the airport or on board, tell staff or cabin crew immediately. If it falls into the seat mechanism, do not move the seat: call a crew member. [IATA passenger safety guidance](https://www.iata.org/en/youandiata/travelers/batteries?ref=roadme.io).

Your check is complete when the actual device’s specifications are established, every sector’s conditions are recorded, required approvals are obtained and the power bank is packed for cabin carriage. Reopen the official policies before departure: an older saved page may no longer describe your flight.
