Electronics are the most expensive thing in most carry-ons and the thing most likely to cause a problem at security. A bit of organization avoids both.
Spare batteries and power banks
Spare lithium batteries and power banks are generally required to travel in the cabin, not in checked bags, and are usually limited by their watt-hour rating. Airlines and regulators publish the details, and limits can differ by airline, so check yours before you fly. If you are buying a power bank for travel, read its rating on the label and keep the label legible.
Keep the kit organized
- One pouch for cables, one for chargers; our Tech & power section lists organizers.
- Wrap cables loosely; tight bends damage them over time.
- Keep tech together at the top of the bag so you can pull it out quickly.
Adapters and chargers
Different countries use different plugs. A single multi-region adapter is usually enough, and a multi-port GaN charger lets you charge a laptop, a phone and a tablet from one socket. Check the voltage range of each device; most modern chargers handle a wide range, but always confirm on the charger’s label.
At security
- Be ready to take out laptops and large electronics when asked.
- Keep devices charged in case you are asked to power them on.
- Check your airline’s rules for large battery packs or e-bikes.
Protect what you carry
Use a padded sleeve for a laptop and keep headphones in a case. A backpack with a dedicated laptop compartment that does not rest on the bag’s base is worth looking for; see how to choose a travel backpack.
Frequently asked questions
Can I put a power bank in checked luggage?
Spare lithium batteries and power banks are typically required to be in carry-on baggage. Check your airline’s rules.
Do I need a voltage converter?
Most modern phone and laptop chargers accept a wide voltage range, so you often only need a plug adapter. Check the label on each charger.
Can I charge on the plane?
Many aircraft have seat power or USB, but not all. Bring a power bank in your cabin bag.
