Headphones-only overnight travellers
If you are charging just one pair of headphones or one charging case, concentrate on the required cable and charger port rather than extra ports you will not use.
Who needs which setup?
One-socket multi-device travellers
If your headphones and phone or tablet must share a hotel socket, check that the charger accepts both cables and how its output is allocated when both ports are occupied.
International hotel guests
For a stay outside the UK, check the destination socket and the charger’s input rating as well as its USB connection. Electrical Safety First notes that a travel adaptor changes plug fit, not voltage or frequency.
What matters when choosing?
Start with the connection your headphones require and how you can charge them safely. Then consider a second device or an overseas socket if either applies to your stay.
| Concern | Buying checks | Who this matters to |
|---|---|---|
| Cable and headphone compatibility | Check the headphone or case connection, the cable’s charger-end connector and the maker’s charging instructions. Sony UK Support warns that charging-only cables can cause problems for some of its headphones. | If my headphones need a particular cable, I want a charger port it actually fits. Around 36% of consumers would put connection compatibility first. |
| Electrical safety | Choose an undamaged charger and cable, and keep the charger dry and uncovered during use. Electrical Safety First advises against charging overnight or while away. | When charging in a hotel room, I want to keep the charger clear of bedding and unplug it when charging is complete. Safe use would come first for roughly 29% of consumers. |
| Sharing one socket | Match the ports to both cables and check the stated output with both ports occupied. A total wattage figure alone does not describe every port’s simultaneous output. | If my phone and headphones need the same socket, I want to know whether both can be connected as intended. About 21% of consumers would make two-device charging their primary concern. |
| Overseas use | Check the destination socket, the charger’s input label and any travel adaptor’s rating. Electrical Safety First notes that adaptors do not convert voltage or frequency. | For a hotel abroad, I need the plug to fit and the charger to suit the local supply. Destination compatibility would be the main concern for around 14% of consumers. |
Mistakes to avoid
-
Buying a USB-C charger without checking the cable
The connection on the headphones or case does not necessarily match the end of the cable that goes into the wall charger. Apple documents different cable requirements across AirPods models, while Sony UK Support cautions that charging-only cables can be problematic for some headphones.
Identify both cable connectors and follow the charging instructions for your exact model before choosing a charger port.
If your existing lead does not fit, you may need a suitable replacement cable or a different charger.
-
Assuming total wattage is available at every port
Output can change when two devices are connected. The BluCore dual-port listing on Joybuy specifies 5V/3A combined output when both ports are used, rather than its advertised 30W single-port maximum.
Read the exact charger model’s per-port and combined-output details before relying on it for headphones and a second device.
-
Covering the charger or leaving it charging overnight
A charger needs a clear space during use. Electrical Safety First advises against using USB chargers overnight or while away.
Keep the charger dry and uncovered, away from bedding and curtains, and unplug it after charging where practical.
-
Assuming a travel adaptor solves every overseas connection problem
Electrical Safety First explains that a travel adaptor changes the plug connection but does not convert voltage or frequency.
Before departure, compare the destination socket and mains supply with the charger’s input label, and check the adaptor’s maximum rating.
You may need to carry a suitable travel adaptor as well as the charger.
Relevant charger brands
Anker
Anker’s A2337 is an example of a compact, single-port USB-C charger to consider when only one compatible device needs the socket.
- Anker UK specifies 30W output and 100–240V input for the A2337 model.
- Its one USB-C port cannot take a second wired device at the same time; check your headphone maker’s charging instructions before use.
Belkin
Belkin’s WCB006 dual USB-C charger illustrates an option for headphones and another device that both use suitable USB-C cables.
- Belkin UK specifies two USB-C Power Delivery ports, 40W total and up to 20W from each port for this model.
- The port specification does not establish compatibility with every pair of headphones; both devices also need suitable cables.
Apple
Apple’s 35W Dual USB-C Port Power Adapter is relevant if you want to charge AirPods and another compatible Apple device from one socket.
- Apple says the adapter can charge two devices at once and lists AirPods among its uses.
- Apple sells the charging cable separately; check which cable your specific AirPods model requires.
Joybuy charger options
These UK-plug chargers offer USB-C charging connections, with different port arrangements for a hotel stay. Match the charger to your headphone cable and charging instructions before deciding whether extra ports are useful.

Cygnett PowerPlus 32W USB-C Dual-Port Charger, White (UK Plug)
Consider this if you want two charger ports at one hotel socket and your headphone cable matches a port. It is a 32W USB-C dual-port wall charger with a UK plug; check the output available when both ports are used.

ACEFAST A97 PD100W GaN Charger (3 USB-C, 1 USB-A; UK)
Consider the mixed USB-C and USB-A ports if the devices you take to the hotel use different cable ends. This UK-version charger has three USB-C ports and one USB-A port; check the output when multiple ports are occupied and follow your headphone maker’s charging instructions.

j5create JUP1565DCF3A 67W GaN PD USB-C Mini Charger with 3 DC Connector Types (UK)
Consider its USB-C charging connection only if it suits the cable and instructions for your headphones. This UK-version 67W charger is listed with three types of DC connector; those connectors do not establish headphone compatibility.
Frequently asked questions
Can I use a higher-wattage USB-C charger for wireless headphones?
Check the charging instructions for your exact headphones or case before using one. Electrical Safety First explains that fast USB chargers can negotiate higher voltages, but a charger’s advertised wattage alone does not establish compatibility; Sony UK Support specifies particular adapter limits for some of its products.
Will I need a separate cable?
You may need one if your existing cable does not fit the charger or a cable is not included. Apple sells its 35W Dual USB-C Port Power Adapter without a charging cable, and Apple Support says the cable required for AirPods depends on the model.
Should I leave headphones charging overnight in a hotel?
Electrical Safety First advises against using USB chargers overnight or while away. Keep the charger dry, uncovered and clear of bedding and curtains, and unplug it when charging is complete where practical.
Can I use a UK charger in a hotel abroad?
Only after checking the destination socket and the input rating on that charger. Electrical Safety First notes that a travel adaptor does not convert voltage or frequency, so plug fit alone is not enough.
