Who needs a replacement charger?

Phone and tablet owners with a missing charger

You need to replace an adapter or cable without assuming that a familiar-looking USB connector provides the charging mode your device accepts.

Laptop owners replacing a power supply

You need to match the exact laptop model, connector and power requirement. A similar-looking plug is not enough to identify a suitable adapter.

Consumers hoping to share one charger

You want one USB-C setup for several compatible devices, but need to check each device’s USB PD support, the laptop’s power requirement and the cable’s capability.

What should you check before buying?

For an everyday phone, tablet or laptop, establish the device’s charging requirements first. Then decide whether you need a complete adapter, a cable or a setup you can use across compatible devices.

Concern What to check Who this matters to
Device compatibility and power Find the exact device model and check the manufacturer’s charging method, connector, required wattage and any USB PD requirement. If my laptop charger is missing, I need an adapter that meets its power requirement, not just a plug that fits. Roughly 31% of consumers would put compatibility and adequate power first.
Safety and traceability Check the manufacturer and model number, the seller’s identity and whether the product appears in recall information; do not rely on a marking alone. If a replacement listing is unfamiliar, I want to know who made the charger and who is supplying it. Roughly 31% of consumers would make safety and traceability their primary concern.
Shared charging Confirm that each device accepts the proposed charging method, then check the adapter’s output when its ports are used together and the cable’s power capability. When travelling, I would rather carry one adapter for my compatible devices without leaving my laptop short of power. Around 19% of consumers would put shared-charging convenience first.
Which component to replace Identify whether the cable or adapter is missing or damaged; retain a component only if it is identifiable, undamaged and suitable for the device. If only my cable is missing, I want to keep an adapter I know is suitable. For around 19% of consumers, identifying the component to replace would be the main concern.

Charger replacement mistakes to avoid

  • Assuming a USB-C plug guarantees compatibility

    USB-C describes the connector, not every charging method or power level. An adapter with insufficient output may charge a laptop slowly or inadequately; a phone’s faster charging mode may require a particular adapter and cable combination.

    Check the exact device’s charging guidance, then compare its wattage and protocol requirements with the adapter and cable you plan to use.

  • Trusting a broad compatibility list without a product identity

    The Office for Product Safety and Standards reported a counterfeit Type-C laptop charger presenting a serious fire risk in 2025. A list of laptop brands, or a safety mark on its own, cannot establish that a particular charger is genuine or suitable for your model.

    Look for a traceable manufacturer and model number, use the device maker’s parts guidance where available, and choose a supplier you trust.

  • Changing the cable while continuing to use a suspect adapter

    A new cable cannot address damage or an uncertain identity in the power adapter. London Fire Brigade advises choosing a genuine replacement from a trusted supplier.

    Inspect both components. Stop using an adapter with visible damage, burn marks or signs of overheating, and check relevant product recalls before choosing a replacement.

  • Expecting a higher-wattage adapter to unlock faster charging

    The device and charging setup determine which mode is available. Samsung UK states that its 45 W Super Fast Charging setup requires both a 45 W travel adapter and a 5 A cable.

    Check your device’s supported charging mode and the exact adapter and cable requirements. For a multi-port adapter, also check its stated output when more than one port is in use.

Brands to consider for model-specific guidance

A brand name helps you find the right support information, but the replacement still needs to match your particular device and charging connection.

Apple

Relevant to iPhone, iPad and Mac owners looking for a replacement suited to their model.

  • Apple Support publishes Mac-specific adapter recommendations and says Macs that charge by USB-C can use a USB PD adapter that meets the model’s recommended minimum wattage.
  • Recommended wattage and cable type vary by Mac model; the Apple name alone does not establish the right laptop replacement.

Samsung

Relevant to Galaxy phone and tablet owners checking which adapter-and-cable combination supports their device’s charging mode.

  • Samsung UK distinguishes charging modes by device and specifies a 45 W travel adapter with a 5 A cable for its 45 W Super Fast Charging setup.
  • A higher-rated adapter cannot give an unsupported Galaxy model a faster charging mode.

Microsoft

Relevant to Surface owners checking a Surface Connect replacement or the charging requirements of a USB-C-capable model.

  • Microsoft Support lists charging requirements by Surface model and strongly recommends genuine Microsoft or Microsoft-licensed accessories.
  • Surface ports and power requirements differ between models, so the exact device must guide the choice.

Lenovo

Relevant to Lenovo laptop owners identifying a USB-C, Slim Tip or Round Tip replacement.

  • Lenovo Support provides parts lookup using machine information or a part number and distinguishes adapters by connection tip and wattage.
  • You still need the correct machine identifier; selecting by brand or plug appearance alone can leave the adapter choice ambiguous.

Replacement charger questions

Will any USB-C charger work with my USB-C device?

No. Confirm that your device accepts charging through that port, then check its required charging protocol and wattage. Apple Support says a Mac that charges by USB-C can use a USB PD adapter, but its recommended minimum wattage depends on the Mac model.

Can I use an adapter with a higher wattage rating?

A higher rating does not by itself make charging faster. Check the exact device’s charging guidance and the adapter’s supported outputs; the device must support the charging mode you expect to use. Samsung UK also specifies an appropriate cable for its 45 W Super Fast Charging setup.

Should I replace the cable, the adapter or both?

Replace only the missing or damaged component if the one you keep is identifiable, undamaged and suitable for your device. If an adapter shows damage or signs of overheating, stop using it rather than relying on a cable change.

Does a UKCA or CE mark prove a charger listing is genuine?

No. Electrical Safety First advises checking a manufacturer name and model number as well as relevant markings, without relying on the marks alone. Check the seller and the product identity before deciding whether the charger matches your device.

What if I suspect a replacement charger has been recalled?

Stop using a charger you suspect is unsafe and check the Office for Product Safety and Standards product recalls and alerts service. Follow the instructions for the specific product and contact the place of purchase where directed.
