Phone-first day travellers
If your phone holds tickets, maps and messages, a compact backup can help you keep it usable through a train, coach or airport delay. Check that its connector suits your phone before relying on a built-in cable.
Who needs which setup?
Laptop-dependent business travellers
If you need to work between meetings or away from a socket, match the laptop’s USB-C charging requirements to the power bank or charger, including its output when other devices are connected.
Air travellers carrying a power bank
Check the operating airline’s current rules for your battery and how it must be carried. Keep your phone or laptop charged enough to switch on if airport staff ask.
What matters when choosing?
Start with where you will charge: a power bank supplies backup away from sockets, while a wall charger needs mains access. Then match the output, cables and flight arrangements to the devices you will actually carry.
Power bank
Choose when: You need to charge a device between stops or during a delay without access to a socket.
Trade-off: It adds a battery to carry and, when flying, must meet the operating airline’s rules.
Multi-port wall charger
Choose when: You expect mains access and want to charge a laptop and phone from one outlet.
Trade-off: It cannot provide power away from a socket, and output may be divided between ports.
| Concern | Buying check | Who this matters to |
|---|---|---|
| Backup energy and bulk | Compare the labelled capacity in Wh and mAh with the devices and time you expect to spend away from mains power. | On a long journey, I need enough backup for my essential devices without carrying more battery than I want. About 31% of consumers put usable energy and carrying size first. |
| Laptop and multi-device output | Check the laptop’s USB-C charging requirement, the power output and any split when multiple ports are used; match the cable’s stated capability too. | If I work between stops, my laptop and phone need a charging setup that suits them together. Adequate output is the primary concern for about 31% of consumers. |
| Flight and battery safety | Check the operating airline’s current capacity, quantity, carriage and in-flight-use rules, plus any recall notice for the exact model. | Before I fly with a power bank, I need to know how to carry it and whether I can use it on board. Around 23% of consumers place flight rules and battery safety first. |
| Cables and sockets | Match built-in and separate connectors to your devices; for a wall charger, check the plug arrangement for your itinerary. | For a short trip, I want fewer loose cables without arriving with the wrong connector. Keeping the setup simple is the main need for about 15% of consumers. |
Mistakes to avoid
-
Choosing a power bank by mAh alone
Capacity does not tell you whether its output suits a laptop or how its battery fits an airline’s rules. Belkin’s UK range, for example, lists distinct Wh ratings alongside the mAh figures for different models.
Compare the exact model’s labelled Wh rating, USB-C output and intended devices. Check the operating airline’s policy before flying.
-
Assuming you can use any power bank in flight
Airline rules cover more than battery capacity. easyJet says power banks must not be recharged or used to charge other devices on board its aircraft.
Read the operating airline’s current instructions for carriage, storage and use before packing.
-
Expecting headline wattage from every port
Belkin states that its WCH013myBK dual-USB-C charger provides up to 65W from one port, but 45W plus 20W when both are in use.
Check the output allocation for the ports you plan to use together, particularly if one device is a laptop.
-
Overlooking an exact-model recall
The Office for Product Safety and Standards has issued recalls for specified Anker and Belkin power-bank models because of overheating and fire risks. A notice about one model does not identify every product from that brand as affected.
Match your unit’s model and any stated manufacturing period against the recall notice. If it is affected, stop using it and follow the recall instructions.
Brands to consider
Anker
Anker UK lists the Nano A1259 as a 10,000mAh power bank with a built-in USB-C cable and 30W charging for mobile devices.
- The built-in cable is relevant if it matches the device you take on a phone-first trip.
- That mobile-device positioning does not establish suitability for every laptop. The Office for Product Safety and Standards also recalled specific, separate Anker models A1681, A1689 and A1647 in 2025; check any unit by exact model.
UGREEN
UGREEN UK lists a Zapix power bank with 10,000mAh capacity, 30W USB-C wired charging, Qi2 15W wireless charging, a built-in cable and a stand.
- Its wired and wireless options offer different ways to charge a compatible phone.
- Check phone and magnetic-charging compatibility; its wireless feature does not establish that it meets a laptop’s USB-C charging requirement.
Belkin
Belkin UK lists integrated-cable power banks, laptop-oriented power banks and multi-port wall chargers.
- Belkin specifies both single-port and shared-port output for its WCH013myBK charger, allowing you to compare those modes with your devices.
- Check the exact model before buying or flying. The Office for Product Safety and Standards recalled Belkin BPB002 and Playa PB0003 power banks in 2025; those notices are model-specific.

Common questions
Can I take a power bank on a flight departing from the UK?
Check the operating airline’s current rules for your exact battery and flight. Ryanair says devices or batteries exceeding 100Wh are not permitted and requires power banks to be carried on the passenger or in an underseat cabin bag; easyJet allows a maximum of two power banks per person in cabin baggage only. Those are carrier-specific rules, not a single rule for every flight.
Can I use a power bank to charge my phone during a flight?
Only if the operating airline permits it. easyJet says power banks must not be recharged or used to charge other devices on board, so check your carrier’s current in-flight instructions rather than relying on its carriage rules alone.
Why charge my phone or laptop before airport security?
You may be asked to switch on an electronic device. Northern Ireland government travel guidance says a device that does not switch on when requested will not be allowed onto the aircraft. Keep the device itself charged, not just a separate power bank.
Which USB-C cable should I pack for laptop charging?
Choose a cable with a stated power capability that meets the laptop and charging setup’s requirements. The USB Implementers Forum notes that cables do not all have the same capabilities, so the USB-C connector shape alone is not enough to establish suitability.
How do I check whether a power bank has been recalled?
Match its exact model and any applicable manufacturing period against the Office for Product Safety and Standards product-safety alerts and the manufacturer’s recall instructions. Notices for specified Anker and Belkin models do not mean every product from those brands is affected; if your unit is affected, stop using it and follow the recall instructions.
