Earbuds-only desk users
If one socket normally charges only your earbuds case, start with the plug on your existing cable. An extra port is useful only if your charging routine calls for it.
Who is this for?
Students sharing a socket
If you regularly charge earbuds alongside a phone, tablet or another USB device, consider how many ports you need and what the charger specifies for use with several devices connected.
Students replacing a questionable charger
If a charger is lost, damaged or of uncertain origin, prioritise a clearly identified model from a reputable seller. Electrical Safety First advises checking chargers for damage and keeping them ventilated during use.
What matters when choosing?
Check the plug at the charger end of your earbuds cable, then decide whether another device regularly needs the same socket. Charger provenance and safe use matter whichever port arrangement you choose.
| Concern | What to check | Who this matters to |
|---|---|---|
| Cable and port match | Check whether the cable has a USB-A or USB-C plug at the charger end, and whether a suitable cable comes with the charger. | If I already have an earbuds cable, I need a wall charger it will plug into; around 39% of consumers put cable-and-port matching first. |
| Sharing one socket | Count the devices you charge together. For a multi-port model, check the port types and stated output when several ports are in use. | If my phone and earbuds share a desk socket, I would rather connect both than keep swapping chargers. Simultaneous connections are the primary concern for around 23% of consumers. |
| Provenance and safe use | Check the seller and model details, inspect the plug and cable for damage, and follow the maker’s instructions for an uncovered, dry charging position. | If I am replacing a questionable charger, I want a clearly identified model I can use safely in my room; around 38% of consumers prioritise provenance and safe use. |
Mistakes to avoid
-
Trusting an unfamiliar charger on appearance alone
Electrical Safety First has reported a replacement USB charger presenting a serious electric-shock risk. Branding or a familiar-looking case is not enough to judge a mains charger’s construction.
Choose a reputable seller, check the maker and model details, and keep your order information.
-
Checking the earbuds case but not the cable
The wall charger accepts the plug at the other end of the cable, which may be USB-A or USB-C. Apple lists its 20W USB-C Power Adapter with the charging cable sold separately, while Samsung lists the EP-T2510NBEGGB without a data cable.
Inspect both ends of the cable you plan to use and check the charger’s included items before ordering.
You may need a separate compatible cable.
-
Choosing extra ports or wattage without a use for them
A charger with several ports helps when devices are connected together, but its maximum stated wattage alone does not tell you the output available from each port during shared use.
For an earbuds-only routine, consider a compatible single-port charger. If you charge other devices at the same time, check the exact multi-port model’s output information.
-
Charging under bedding or while away
Electrical Safety First advises keeping USB chargers ventilated and away from heat and water, and advises against charging overnight or while out of the house.
Use an open, dry surface, check the charger and cable for damage, and disconnect them after charging.
Brands to consider for USB charging
Apple
Apple offers a USB-C adapter that may suit a setup already using a compatible USB-C charging cable.
- Apple lists its 20W USB-C Power Adapter with one USB-C port.
- Apple sells the charging cable separately. Its AirPods Pro 3 case can charge through USB-C, but that example does not establish the connector or charging requirements of other earbuds.
Belkin
Belkin’s BoostCharge USB-C Wall Charger 25W is a single-port option for a compatible USB-C cable.
- Belkin specifies one USB-C port, up to 25W, USB-C PD 3.1 certification and a two-year warranty for this model.
- One port cannot connect an earbuds cable and another device’s cable simultaneously.
Anker
Anker’s Nano A2337 is a USB-C wall charger to consider if the same adapter will also serve other compatible devices.
- Anker specifies 30W maximum output and PPS support for the A2337.
- That rating does not mean an earbuds case needs 30W. Check the cable and included items for the particular offer.
Samsung
Samsung’s EP-T2510NBEGGB is a UK-plug USB-C option for a compatible cable.
- Samsung lists up to 25W output with PD 3.0 PPS support for this model.
- Samsung lists it without a data cable and says charging speed varies with the connected device and conditions.

Consider this if two connections would suit your socket-sharing routine.

Common questions
Do wireless earbuds need a high-wattage wall charger?
Do not choose extra wattage solely for an earbuds case; start with the case maker’s charging instructions and a charger that fits your cable. The USB Implementers Forum explains that USB Power Delivery allows a device to request the power it requires, but a charger’s maximum rating alone does not establish how a particular case will charge.
Should I buy a USB-A or USB-C charger?
Buy a charger with a port that matches the plug at the charger end of your cable. Electrical Safety First describes USB-A as the rectangular connector and USB-C as the smaller reversible connector; a USB-A-to-USB-C cable needs a USB-A charger port, while a USB-C-to-USB-C cable needs a USB-C port.
Can I leave an earbuds charger running overnight?
Electrical Safety First advises against using USB chargers overnight or while out of the house. Keep the charger uncovered and ventilated, away from water and heat, and disconnect it after charging.
Do I need a charger that comes with a cable?
A cable included with the charger is useful if you do not already have one with the right plug at the charger end. Check the contents of the particular offer: Apple says the cable for its 20W USB-C Power Adapter is sold separately, and Samsung lists the EP-T2510NBEGGB without a data cable.
