Start with your phone model, not the charger wattage: confirm its port, supported wired or wireless charging standard and maximum charging capability, then choose a charger and cable for that route. A higher-wattage USB-C charger can be useful for shared devices or future use, but it cannot make a phone charge above its supported rate. For Galaxy 45W charging, Samsung specifies USB PD 3.0 and Direct Charging support plus a 5A cable.
Match the phone connector, supported charging standard, cable type and UK plug before treating a charger as compatible. Electrical Safety First, Apple Support (UK) and Google Pixel Phone Help all highlight model and connection requirements.
Distinguish ordinary charging, Super Fast Charging and Super Fast Charging 2.0. Samsung UK states that the 45W route depends on the particular Galaxy model, USB PD 3.0 and Direct Charging support, plus a 5A cable.
A multi-port charger can suit a phone and another device, but check its per-port allocation and combined output. A total-wattage label does not promise the same output to every connected device.
Confirm the phone and cable route first, then check the plug, power arrangement and listing details before comparing charger wattage.
| Priority | What to check | Your needs |
|---|---|---|
| Charging compatibility | Check the phone port, supported charging standard and the manufacturer’s stated charging capability. For compatible third-party iPhone fast charging, Apple Support (UK) specifies USB Power Delivery. | I want an adapter and cable that physically connect to my phone and use its supported charging route, rather than paying for output it cannot use. |
| Cable capability | Check both cable ends, stated power capability and whether a cable is included. USB-IF identifies certified USB-C-to-USB-C cable power markings as 60W or 240W; Samsung UK specifies a 5A cable for its 45W charging combination. | I need to know whether my current cable works, or whether I need USB-C-to-USB-C for a USB-C phone or USB-C-to-Lightning for an earlier iPhone. |
| Electrical safety | Check the seller and manufacturer details, the UK plug format and product information. Keep chargers away from liquids and heat, and do not use damaged plugs, cables or adapters. | I want a traceable replacement charger from a reputable retailer, rather than relying on a familiar phone name or safety wording in a marketplace title. |
| Shared and wireless charging | For multi-port chargers, read the per-port and combined-output table. For wireless charging, confirm the phone’s supported standard, case compatibility and alignment requirements. | I need to allow for output being shared between devices, or accept a more condition-dependent charging route when choosing wireless convenience. |
A charger’s maximum output is not the phone’s actual charging rate. Apple Support (UK) and Samsung UK both set model- and protocol-dependent conditions, while Samsung adds a 5A-cable requirement for its 45W route.
Look up the exact phone model, then match the connector, USB-PD/PPS or manufacturer-specific requirements and cable capability before comparing wattage.
The wrong cable end prevents connection, while an insufficiently specified cable can block an intended high-power route. USB-IF distinguishes certified USB-C-to-USB-C cables by 60W or 240W capability, and Samsung UK specifies a 5A cable for 45W charging.
Check the box contents, both connector ends and the cable’s stated power rating. For Samsung 45W charging, confirm the 5A-cable condition rather than relying on a generic USB-C label.
A separate compatible cable may be needed: the Apple 20W adapter listing states that no charging cable is included.
Electrical Safety First advises against substandard or counterfeit third-party USB chargers. The Office for Product Safety and Standards documented a replacement 20W USB-C phone charger sold online that presented a serious electric-shock risk.
Prefer a reputable retailer, retain seller and manufacturer details, check recall information and stop using a charger with damage, scorch marks or uncertain provenance.
Power can be shared or prioritised between ports, while wireless speed depends on phone support, charger standard, alignment, case compatibility and temperature.
Read the per-port and combined-output table for multi-port units. For wireless charging, verify the phone’s supported standard and use a compatible charger where the manufacturer specifies one.

For charging a compatible USB-C phone alongside a lower-power accessory.
Stated outputs are 20W USB-C PD and 12W USB-A, with a foldable UK plug. The 32W figure is total output, so use the individual port ratings for simultaneous charging.
Check whether a cable is included, and confirm the phone’s connector and supported charging standard before buying.

For a straightforward wired replacement setup with a supported iPhone or iPad and the correct cable.
This single-port adapter has a stated 20W USB-C output and UK three-pin plug.
A charging cable is not included; choose USB-C-to-USB-C or USB-C-to-Lightning according to the device port. The 20W rating is not a guaranteed charging speed.
No image available
For replacing a cable between a USB-C phone and a USB-C wall charger.
The cable has USB-C connectors at both ends, a stated 60W charging capability, USB 2 data transfer and a 1m length.
It does not include a wall adapter and is not suitable for Lightning-port iPhones. Its stated 60W capability does not raise the phone’s own charging limit.
No image available
For an earlier iPhone or iPad with a Lightning port used with a USB-C power adapter.
This 1m cable has USB-C-to-Lightning connectors and supports charging and data syncing.
A USB-C wall adapter is required and is not included. Check the device port, as newer USB-C iPhones need USB-C-to-USB-C instead.
No image available
For Lightning-device charging from a USB-C PD adapter where a longer everyday cable is useful.
The listing states USB-C-to-Lightning connectors, up to 30W charging, 480Mbps data transfer, braided construction and a 1.2m length.
A separate USB-C wall adapter with a suitable UK plug is required. It is not for USB-C-port phones, and its stated capability does not guarantee a particular device charging rate.
A compatible charger is designed to negotiate power with the device, so a larger wattage label does not make the phone charge above its supported rate. Electrical Safety First explains that fast chargers use a digital handshake and default to 5V if communication fails, but the charger, cable and phone must still be compatible.
Possibly: check the charger port, phone port and box contents first. A USB-C iPhone needs USB-C-to-USB-C charging, while an earlier Lightning-port iPhone needs USB-C-to-Lightning for Apple’s wired fast-charge arrangement; Samsung specifies a 5A cable for its 45W charging combination.
For a normal UK wall socket, choose a charger supplied with a UK three-pin plug or use an appropriate safe solution specified for that product. Do not assume an EU-plug charger fits directly, and check the plug type on the exact listing before buying.
The Office for Product Safety and Standards states that the Electrical Equipment (Safety) Regulations 2016 set requirements before electrical equipment is placed on the Great Britain market. These obligations principally apply to manufacturers and other economic operators, so still check the exact listing, seller identity, plug type and recall information before purchase.
It can be suitable if the phone supports wireless charging and convenience matters more than the quickest wired top-up. Google Pixel Phone Help says Pixel support varies by model, while heat, alignment and an incompatible case can affect charging.
