Choose a replacement by matching your phone’s connector and charging requirements to the charger and cable, rather than buying on wattage alone. A multi-port charger needs enough output at the ports you will use together; wireless charging is a separate convenience option if the phone, case and charger are compatible, but it will not replace a wired connection you need for data transfer.
If a charger is missing or has stopped working, matching the phone’s connector, charging method and cable capability matters more than choosing the largest wattage printed on an adapter. Apple and Google’s charging guidance gives model-specific requirements to check.
An extra charging point at a desk, bedside or in a travel bag may need more than one port. Check the output available when devices are connected together: Google’s guidance for its Pixel Flex Dual Port charger describes output that changes with device demand and prioritisation.
A pad or stand can suit a desk or bedside if the exact phone supports Qi or Qi2 and its fitted case works with the charging arrangement. It does not provide a wired data connection or charging for a phone without compatible wireless hardware.
Start with the phone and the connection it needs. Then decide whether the replacement must serve one device, share an outlet or allow wireless placement.
| Concern | What to check | Who this matters to |
|---|---|---|
| Wired compatibility | Check the exact phone model, both cable ends, and the charger’s stated charging protocol and output. Check the cable’s power rating where relevant. | If I want the wired charging my phone supports, a fitting connector alone is not enough; around 36% of consumers put compatibility and charging capability first. |
| Safety and traceability | Identify the charger’s brand and model, check current product-safety alerts and recalls, and inspect its condition. Consult the supply guidance applicable to Great Britain or Northern Ireland. | When replacing a mains charger, I want to identify the product and check for safety notices before using it; about 29% of consumers make safety and traceability their primary concern. |
| Shared charging | Check the port types and the manufacturer’s output information for all the ports you intend to use at once. | At a shared outlet, I need to connect more than one device without assuming each port retains its single-port output; roughly 21% of consumers prioritise multi-device charging. |
| Wireless convenience | Confirm Qi or Qi2 support for the exact phone and check case compatibility and alignment requirements. | For bedside charging, I would rather place a compatible phone on a pad than connect a cable; around 14% of consumers put wireless convenience first. |
A charger’s rated wattage does not establish what a particular phone will accept. Samsung says its Super Fast Charging 2.0 requires a compatible USB Power Delivery 3.0 device with Direct Charging support; Google also documents charging profiles for particular products.
Check the phone maker’s charging requirements against the adapter’s protocol and output and the cable’s capability. For a multi-port adapter, read the outputs specified with your intended ports in use.
Connector shape does not tell you a cable’s power rating. The USB Implementers Forum says USB-C-to-USB-C cable categories in its compliance programme carry 60W or 240W power-capability labels.
Match both cable ends to the phone and charger, then check its stated rating against the charging setup you need.
A cable that does not meet the required power capability may need replacing even if both connectors fit.
Wireless charging depends on the phone, charger and their placement. Google advises checking case compatibility for Qi2 charging and notes that heat can affect wireless charging.
Confirm support for the exact phone and fitted case. If a product claims Qi or Qi2 certification, check its certification details with the Wireless Power Consortium.
A charger working now is not a substitute for checking its condition or relevant safety notices. The Office for Product Safety and Standards publishes product-safety alerts and recalls; Google warns against using chargers with damaged housings or plug blades.
Keep the product’s model details for a recall search, and stop using charging equipment that is damaged, wet or abnormally hot.

Match the exact phone model’s stated connector, charging protocol and cable requirements to the products you plan to use. Apple describes USB-C Power Delivery for faster wired charging on applicable iPhones, while Samsung sets specific device requirements for its Super Fast Charging 2.0 mode. A higher adapter wattage alone does not establish the mode your phone will use.
No. The USB Implementers Forum identifies 60W and 240W power-capability labels for USB-C-to-USB-C cable categories in its compliance programme. Check the cable’s stated rating and both connectors against your phone and charger.
A wireless pad makes sense for convenient placement when the exact phone supports Qi or Qi2 and its case works with the charging arrangement. It cannot replace a wired connection needed for data transfer or serve a phone without compatible wireless charging. Google also notes that heat can interrupt wireless charging.
Search the current GOV.UK Product Safety Alerts, Reports and Recalls service using the brand, model or other identifying details. Keep those details so you can compare a notice with the product you own or intend to buy.
Check the guidance for the destination rather than treating the two as identical. GOV.UK’s guidance on the Electrical Equipment (Safety) Regulations 2016 addresses equipment placed on the Great Britain market; it publishes separate Northern Ireland guidance on applicable marking arrangements.
