Choose a power bank if you need to charge between sockets, a plug adaptor if your existing charger will not fit the destination socket, or a multi-port mains charger if you expect access to wall power for several devices. Before buying, match the charger and cable to each device, check the destination’s electrical supply, and review your operating airline’s current battery rules.
If you expect to need reserve power during a journey, consider a power bank with a readable watt-hour (Wh) marking. The UK Civil Aviation Authority says power banks belong in the cabin rather than checked luggage; check your operating airline’s capacity and quantity rules too.
If you carry a phone alongside a tablet, camera or other USB device, a multi-port mains charger may replace several charging plugs. Match its ports, shared output and cables to the devices you plan to charge together.
Check whether your laptop accepts USB-C charging, what power supply and cable it requires, and whether your charger’s plug fits the destination socket. Electrical Safety First notes that a plug adaptor does not convert voltage or frequency.
Start with where you will charge: away from sockets, at a wall socket, or both. Then check each device’s charging requirements before choosing cables or a destination plug adaptor.
Choose when: You need reserve power between mains sockets.
Bear in mind: It adds something to carry and must meet the operating airline’s battery and cabin rules.
Choose when: You expect wall-socket access and want to charge several devices from one unit.
Bear in mind: Available output may differ when several ports are in use.
Choose when: Your charger’s plug does not fit the destination socket but its input rating suits the local supply.
Bear in mind: It changes plug fit, not voltage or frequency, according to Electrical Safety First.
| Concern | What to check | Who this matters to |
|---|---|---|
| Power away from sockets | Read the power bank’s Wh marking and check the operating airline’s current capacity, quantity and cabin rules. | If I cannot count on finding a socket during my journey, reserve power matters more than another wall charger. Around 30% of consumers put charging away from sockets first. |
| Charging several devices | Match the number and type of ports to your devices; check the charger’s output when ports are used together. | When I can use a wall socket, I would rather carry one compatible charger for my phone and other devices than several plugs. Around 30% of consumers prioritise this shared mains-charging need. |
| Laptop charging | Confirm the laptop’s charging method and required input, then match the charger’s port output and cable rating. | If my laptop needs charging on the trip, a connector that fits is not enough: the complete setup has to meet its requirements. This is the primary concern for around 20% of consumers. |
| Destination socket and supply | Check the destination socket, the equipment’s input label and the adaptor’s rating. | At my destination, I need to know that my charger both fits the socket and accepts the local electrical supply. Around 20% of consumers put that compatibility check first. |
Battery-capacity rules are expressed in watt-hours (Wh), so an mAh figure alone does not settle whether a power bank meets your airline’s policy.
Read the Wh marking on the unit and compare it with the operating carrier’s current rules rather than relying on a general flight-suitability claim.
The UK Civil Aviation Authority directs passengers to keep power banks and spare lithium batteries in the cabin, not checked luggage.
Keep them with you, and remove them if staff take your cabin bag for hold loading.
Electrical Safety First states that a travel adaptor changes plug compatibility but does not convert voltage or frequency.
Check the equipment’s input label against the destination supply, along with the adaptor’s rating and any earth-connection requirement.
Equipment that cannot accept the destination supply may require a suitable converter or transformer as well as a plug adaptor.
A USB-C connector alone does not establish that the laptop, charger and cable support the required charging level. The USB Implementers Forum specifies particular cable requirements for higher-power USB Power Delivery.
Check the laptop maker’s charging requirements, the charger’s output at the port you intend to use and the cable’s stated power rating.
Anker’s UK range includes USB chargers, travel adaptors and USB-C power banks for different charging setups.
Belkin’s UK travel-charging products include multi-port USB-C mains chargers and plug-adaptor kits.
Apple’s UK accessory range includes USB-C power adapters and USB-C to MagSafe 3 cables for relevant MacBook setups.
No. The UK Civil Aviation Authority says to keep power banks and spare lithium batteries in the cabin, not checked luggage. Remove them if your cabin bag is taken for hold loading, and check your operating airline’s additional rules.
No: a capacity below 100Wh is not a universal permission to carry or use a power bank. Check the operating airline’s current capacity, quantity, packing and onboard-use rules for your trip; Virgin Atlantic, for example, requires approval for certain power banks between 100Wh and 160Wh.
No. Electrical Safety First says a travel adaptor changes plug fit but not voltage or frequency. Check your charger’s input label against the destination supply before using it.
Electrical Safety First identifies the UK socket as Type G and the supply as 230V at 50Hz. Check that your equipment accepts that supply; a plug adaptor alone will not change it.
Yes, if you are asked to switch them on. GOV.UK advises charging electronic devices before travel and says a device that will not switch on when requested cannot be taken onto the aircraft.
