Who is replacing a charger?

Replacing a lost or damaged charger

You need a plug and cable that connect to your device and support its charging arrangement. If ordinary charging meets your needs, there is no reason to choose solely by the largest output figure.

Keeping a documented fast-charge mode

Your phone or tablet supports a particular faster wired-charging arrangement. Check the exact model’s requirements for the adapter and cable rather than assuming that any USB-C combination will provide it.

Charging several devices

You want one charger for a phone, tablet or other USB-powered devices. The useful comparison is the output available with your intended ports occupied, not just the charger’s headline total.

What should you check before buying?

Match the device, cable and wall charger as a set. If several devices will share a charger, check its output with those ports in use.

Concern What to check Who this matters to
Connector and charging arrangement Check the ports on the device and charger, then choose a cable with the right connector at each end. Confirm the device’s documented wired-charging requirements. If my charger has gone missing, I need a replacement combination that fits my device and charges it as intended. Around 31% of consumers put that match first.
Retailer and product information Check the seller’s identity and the product’s identification and instructions. Confirm whether it is supplied in Great Britain or Northern Ireland before assessing market-specific markings. When replacing equipment that plugs into the mains, I want a traceable product from a retailer I can identify. For around 31% of consumers, source and safety information are the primary concern.
Documented fast charging Compare the exact device model’s required charging standard and adapter output with the cable capability it specifies. If my device supports faster wired charging, I want the replacement to retain that mode rather than merely fit the socket. Around 25% of consumers prioritise this requirement.
Power sharing Check the number and type of ports and the stated output allocation when several are occupied. At a shared desk or while travelling, I may need one plug to charge several devices together. Making that arrangement work is the leading need for around 13% of consumers.

Mistakes to avoid

  • Assuming USB-C guarantees fast charging

    USB-C identifies a connector, not the charging mode a device will use. Apple specifies USB Power Delivery (USB-PD) for its stated fast-charging arrangement on supported iPhones; Samsung UK sets different conditions for particular Galaxy charging modes.

    Look up the exact phone or tablet model, then match its required adapter standard, output and cable.

  • Reusing a cable without checking its capability

    The USB Implementers Forum distinguishes USB-C cables by capability. Google says a device requiring more than 60W with its Pixel Flex Dual Port 67W Charger needs an e-marker cable certified above 60W.

    Compare a replacement cable’s stated power capability with the requirements of both device and charger.

    An unsuitable cable may need replacing even if its connectors fit.

  • Reading total output as the output of every port

    A multi-port charger can allocate power differently when another device is connected. Google’s guidance for its dual-port charger describes output that changes according to connected-device priority.

    Read the output allocation for the number of ports you expect to use simultaneously.

  • Choosing an unclear third-party listing

    Electrical Safety First advises buying USB chargers from reputable retailers rather than third-party online sellers because products from the latter may not have passed necessary safety checks. A marking alone does not establish that a particular listing is genuine or suitable for your device.

    Check the retailer, product identification and applicable market information alongside the charging specifications.

Relevant brands for reference

Apple

A device-specific reference for iPhone and iPad charging, particularly when replacing equipment for a Lightning-port iPhone.

  • Apple Support distinguishes the USB-C cable used by supported newer iPhones from the USB-C to Lightning cable needed for its stated fast-charging arrangement on earlier models.
  • An Apple-branded adapter is not required for every supported arrangement: Apple also describes comparable third-party USB-C adapters that support USB-PD. Check the requirements for your model.

Samsung

A reference for Galaxy owners comparing a replacement with their exact model’s supported charging mode.

  • Samsung UK says its 45W charging arrangement requires a 45W travel adapter and a 5A cable for compatible devices.
  • Galaxy charging requirements vary by model. A 45W adapter alone does not establish that a particular phone or tablet will use that mode.

Google

A reference for Pixel owners considering a dual-port USB-C charger for a phone and another device.

  • Google describes how its Pixel Flex Dual Port 67W Charger adjusts output according to the connected devices.
  • Its port-priority rules matter when devices share the charger; Google also specifies an e-marker cable certified above 60W for a device requiring more than 60W.

Anker

A third-party brand with a multi-port charging option for a desk or shared-device setup.

  • Anker describes its Prime A2345 as a six-port charger with 250W total output.
  • Those are claims for that model, not specifications for every Anker charger. Check the exact product’s port allocation and the cables your devices require.

Frequently asked questions

Will any USB-C charger fast-charge my phone?

No: USB-C describes the connector, not a guaranteed charging speed. Check your exact device model’s charging standard, adapter requirements and cable; Apple and Samsung, for example, specify different conditions for supported fast-charging arrangements.

Can I replace my phone charger with one rated for higher wattage?

A higher maximum rating alone does not mean your phone will charge faster. Choose a charger with a compatible charging arrangement, then check the phone manufacturer’s requirements before expecting a particular fast-charge mode.

How do I choose a USB-C cable for a higher-power device?

Match the cable’s stated power capability to the device and charger. The USB Implementers Forum describes 60W and 240W power markings for USB-C-to-USB-C cables in its compliance programme; Google says a device needing more than 60W with its Pixel Flex Dual Port 67W Charger requires an e-marker cable certified above 60W.

Which product marking should a UK-supplied charger carry?

Check where the charger is supplied before applying marking guidance. Department for Business and Trade guidance discusses CE and UKCA marking for relevant products in Great Britain, while its separate Northern Ireland guidance covers CE and, in applicable circumstances, CE plus UKNI. A mark alone does not establish that a listing is genuine or compatible with your device.

Should I keep using a damaged charger or cable?

Do not continue using charging equipment that shows signs of damage. Electrical Safety First advises checking plugs and sockets for burn or scorch marks and protecting chargers from damage, heat and liquids; follow the manufacturer’s instructions for the equipment.
