Choose a replacement by checking the exact device model, its manufacturer's charging guidance and the connectors at both ends of the cable. A manufacturer-recommended charger is the clearer route when requirements are model-specific; a USB-C Power Delivery (PD) adapter or multi-port charger needs checks for device compatibility, cable capability and the power available to each port. For delivery to Great Britain, check product and seller information against the applicable GB requirements; Northern Ireland has separate product-supply guidance.
If one item is lost or damaged, focus on the known device's connector and manufacturer guidance before considering extra ports. West Yorkshire Fire and Rescue Service advises using the supplied charger or a replacement recommended by the manufacturer.
A matching plug shape is not enough when the device requires USB-C PD and a particular power supply. Microsoft publishes model-specific charging requirements for Surface devices; check the exact model and cable before choosing an alternative adapter.
If several devices need the same outlet, compare the ports and the output available with your intended combination connected. A multi-port charger's stated maximum does not tell you what each port provides at the same time.
Identify the device and its charging requirements first, then check the cable, the seller and any power sharing involved in your intended setup.
| Concern | What to check | Who this matters to |
|---|---|---|
| Device and connector match | Check the exact device model, manufacturer guidance, charging protocol and connectors at both cable ends. | If my charger is missing, I need a replacement for my particular device, not one that merely has a familiar-looking plug. Around 36% of consumers put that exact match first. |
| Safety and delivery destination | Check product identity, seller details and the information applicable to delivery in Great Britain or Northern Ireland; do not use damaged equipment. | When replacing damaged equipment, I want to identify the product and seller and know which destination requirements to check. Safety and sourcing come first for around 29% of consumers. |
| Power and cable capability | For a laptop or tablet, check the model's required wattage and USB-C PD support where applicable, plus the cable's stated suitability. | If I rely on a USB-C laptop, a replacement needs to meet its charging requirements rather than just fit its port. Sufficient power and a suitable cable are the primary concern for around 21% of consumers. |
| Charging several devices | Check port types and the exact model's per-port and combined-output information for the devices connected together. | With several household devices to charge, I would prefer one outlet if it serves the combination I use. That shared setup comes first for around 14% of consumers. |
USB-C identifies the connector, not the charging capability. Microsoft says an unsuitable or lower-wattage arrangement may charge a supported Surface slowly or not at all.
Use the exact model's charging guidance to check USB-C PD support, required wattage and the cable connection before ordering.
Connecting another device can change the power allocated to a port. The headline output alone cannot establish whether the intended laptop-and-phone combination will work as needed.
Read the output table for the exact charger model and the ports you plan to use together.
Apple lists charging cables separately for its cited 20W and 35W adapters, and Microsoft notes that USB-C-compatible cables do not all support the same features.
Check whether a cable is included and confirm its connectors, length and stated suitability for your device.
A listing alone does not establish that a charger is suitable for your device or destination. Electrical Safety First advises buying USB chargers from a reputable retailer.
Check the product and seller details, follow manufacturer instructions and avoid damaged or suspected counterfeit equipment.
A manufacturer-adapter route for compatible iPhone, iPad and Mac models.
A manufacturer-guidance route for Pixel charging accessories.
A model-specific replacement route for Surface power supplies and eligible USB-C PD charging.
A third-party route that includes USB-C and multi-port chargers for shared-device setups.
Match it to the exact device model using the original charger label or manufacturer support page, then check the connectors, charging protocol and required wattage. For eligible Surface devices charging through USB-C, Microsoft specifies USB-C PD and advises checking against the designed power supply's wattage.
A higher output rating alone does not establish compatibility or a faster charge. Check the device manufacturer's supported charging arrangement and the cable before choosing the adapter, particularly where charging requirements are model-specific.
Check the destination before relying on product-supply information. The Office for Product Safety & Standards says electrical equipment must meet applicable requirements before being placed on the Great Britain market; its Northern Ireland guidance addresses a separate framework under the Windsor Framework. A marking or listing should not be treated as proof that an individual charger meets the applicable requirements.
No. Stop using visibly damaged charging equipment and replace the affected item with one suitable for the device. West Yorkshire Fire and Rescue Service advises using the supplied charger or a manufacturer-recommended replacement; do not attempt to modify damaged charging equipment.
