Choose a replacement charger by checking your exact phone model's connector and charging protocol, then matching the charger's single-port output and a suitable cable. A single-port plug suits charging one phone; a multi-port plug needs closer attention to the output available when other devices are connected. Buy through a traceable seller and check product details and current recall information rather than treating a marketplace listing or conformity mark alone as proof of safety.
If an old plug needs replacing or your phone came without one, start with the handset's connector and the charging standard specified for its exact model. Apple's iPhone guidance illustrates why requirements should be checked by generation rather than assumed from the plug's wattage.
If a phone shares one socket with earbuds, a tablet or another phone, check what each port supplies when both are occupied. Google's Pixel charger guidance and Belkin's dual-port specifications show why a charger's total output does not describe every port's output.
If you are considering an unfamiliar charger listing, look for a traceable seller and a clearly identified product. Electrical Safety First advises buying USB chargers from reputable retailers, and the Office for Product Safety and Standards provides a service for checking safety alerts and recalls.
For consumers replacing or adding a mains phone charger, start with the phone's requirements, then check the cable and any shared-port arrangement. Assess the seller and product identity before using the plug.
| Concern | What to check | Who this matters to |
|---|---|---|
| Phone compatibility | Check the exact handset model's connector and charging protocol, then the charger's single-port output. | If I am replacing a plug for one phone, I want to know it supports the charging mode my handset uses rather than choosing by the largest wattage on the box. Roughly 36% of consumers put phone-model compatibility first. |
| Safety and traceability | Identify the seller and charger model; check the Office for Product Safety and Standards recall service. Do not rely on a CE or UKCA mark alone. | When a listing comes from an unfamiliar seller, I want to identify the product and check for safety notices before plugging it in. Around 29% of consumers make sourcing and traceability their primary concern. |
| Shared charging | Compare each port's output with one device connected and with multiple devices connected. | If my phone shares a socket with another device, I need to know whether both can receive the output they require at the same time. For about 21% of consumers, shared-device charging comes first. |
| Cable or wireless fit | Match the cable ends and stated power capability; for wireless charging, confirm the phone, pad and required wall adapter work together. | If I also need a cable or would rather use a charging pad, I want that setup to work with my phone, not just the new plug. Approximately 14% of consumers prioritise cable or wireless fit. |
The phone's supported charging mode, the charger's available output and the cable all affect the arrangement. Google's Pixel charger guidance also notes that connected devices and port-prioritisation rules affect output.
Find your exact phone model's charging guidance before comparing plugs. If you need two ports, read the maker's output figures for simultaneous use as well as single-port use.
A cable must have the right connectors and a suitable power capability. The USB Implementers Forum states that its USB-C-to-USB-C cable categories use 60W or 240W power markings; a USB-C connector alone does not describe every cable's capability.
Check both plug ends and the cable's stated capability against the phone and intended charger.
Electrical Safety First advises buying USB chargers from reputable retailers rather than relying on unfamiliar third-party sellers. For products placed on the Great Britain market, UK government guidance describes CE and UKCA markings as the manufacturer's belief that relevant requirements are met, not an independent check of a particular listing.
Confirm the seller and product model, keep the purchase details, and check current safety alerts and recalls through the Office for Product Safety and Standards.
Wireless output depends on the handset, charging pad and wall adapter. Apple's MagSafe guidance says delivered power varies by iPhone model, adapter and system conditions.
Confirm your phone supports the intended wireless system and check the pad maker's adapter requirements before buying.

These UK-plug wall chargers cover one-phone and shared-socket setups. Match a candidate to your phone's charging requirements and check the cable you intend to use; the wattage in a product name does not establish the output available to every connected device.

Consider this single USB-C charger when replacing a plug for one compatible phone.
The name states PD and 30W; check your phone's required charging mode and whether you need to obtain a suitable cable.

The dual-port arrangement is worth considering when a phone and another device need to share a socket.
The name states 32W; check the output available from each port when both are occupied before relying on a particular charging mode.
Image unavailable
This is a single-device adapter to consider if your exact phone model and cable suit a USB-C power adapter.
The name states 20W; check the handset maker's guidance and whether a compatible cable is included or needed separately.
Image unavailable
Consider its four-port format if several devices need access to one UK socket.
The name states PD and 100W; check the output assigned to each port during simultaneous use and your phone's supported charging mode.

The two USB-C ports and one USB-A port make this a candidate for sharing a socket between devices.
The name states 65 W; compare the per-port and simultaneous-use outputs with your devices' requirements rather than assuming each port supplies that figure.
Not necessarily: a larger stated output does not change the charging mode your phone can use. Check the handset maker's protocol requirements, the charger's relevant port output and the cable before choosing on wattage alone.
No. Apple's charging guidance varies by iPhone generation, including which cable connector to use. Look up your exact model's wired charging requirements before choosing an adapter.
PPS is relevant if your exact Galaxy model supports the Samsung Super Fast Charging mode you want to use. Samsung UK identifies PD 3.0 PPS on its 25W adapter and limits that charging claim to compatible devices, so confirm your handset model first.
No. For products placed on the Great Britain market, UK government guidance describes these markings as the manufacturer's belief that relevant requirements are met. Electrical Safety First advises buying USB chargers from reputable retailers; also identify the seller and model and check current recall information.
Search the Office for Product Safety and Standards Product Safety Alerts, Reports and Recalls service using the brand and model where available. If a notice identifies your charger, stop using it and follow the instructions in that notice.
