Pack power banks and spare batteries for a flight

Use the current airline policy for the exact items

The CAA’s Pack Right, Safe Flight campaign tells passengers to keep power banks in the cabin and check their airline’s instructions. Its separate page on battery-rule changes records updates effective in 2026. Read the operating airline’s detailed policy rather than assuming an older packing checklist includes those changes.

Check how the carrier defines a power bank, how many are allowed, the relevant battery rating and any approval process. Do not infer permission from a capacity number printed in a different unit without following the airline’s guidance. If the required specification is illegible or missing, ask the manufacturer and carrier what documentation is acceptable before deciding to travel with it.

Record the model alongside the marked battery information so a reply from the manufacturer can be matched to the item you actually carry. Similar-looking versions of a product may have different specifications, and a generic family manual may need clarification.

Inspect and organise the items before packing

Check the battery or power bank for obvious damage and consult the manufacturer’s instructions if its condition is uncertain. Use the original protective arrangement or another method specifically suitable for protecting exposed terminals as directed by the airline. Keep loose metallic objects from sharing an unprotected compartment with spare batteries.

A small pouch can help keep the permitted items together and visible when packing. It should not encourage you to conceal an item that staff need to inspect or bury it where you cannot follow the airline’s storage instructions. Remove unnecessary duplicates after checking which devices need power during the journey. Carrying every spare you own is not a charging plan.

Prepare for a cabin bag being taken to the hold

Put the batteries and power bank where you can remove them promptly if staff require a larger cabin bag to be checked. British Airways’ restricted-items guidance expressly tells passengers to remove power banks and spare batteries when a cabin bag is placed in the hold. Check the equivalent instruction for your own flight and comply with the crew’s directions.

Before handover, tell staff if you need a moment to remove an item that must remain in the cabin. Keep your smaller personal bag within the permitted allowance and make sure it has space for these essentials. Do not leave the only charging cable or travel document in the handed-over bag while concentrating solely on the battery removal.

Follow onboard instructions and the same return checks

Do not recharge a power bank on board the aircraft. The CAA passenger guidance effective from 27 March 2026 says power banks must remain in carry-on baggage, be individually protected when not in use and be limited to two per person. It also advises against using them to charge other devices on board. Check the operating carrier for stricter rules and follow the crew’s storage and use instructions. If a device behaves unusually, tell crew promptly and follow their directions.

At the destination, use compatible charging equipment under the manufacturer’s instructions. Before flying home, review the return carrier’s rules and the contents of your electronics pouch, including anything bought during the trip. Keep the specifications readable and any required approval accessible. The practical purchase decision is whether a power bank with a suitable, documented specification fills a real need; size or a travel-themed label alone cannot answer that.

Your next steps

• Identify every power bank and spare battery.
• Check current ratings, quantity and approval rules.
• Keep permitted cabin-only items removable at bag handover.
• Follow the airline’s separate onboard-use instructions.

Keep planning

• Pack fewer clothes with a realistic holiday laundry plan
• Check camping equipment before packing for a flight
• Plan a flight with cabin bags only
• Decide whether evening bag drop helps an early flight
