Start with the device’s charging port and specified power requirements, then check the adapter’s supported output, the cable’s rating and the seller’s product information. A manufacturer-specified replacement can simplify model matching, while a third-party USB charger is an option when its output and the device’s charging requirements are compatible. An extension lead adds socket access; it does not resolve a charger mismatch or replace safer charging and loading practices.
Check the original connector and power requirement before choosing a replacement. Dell, for example, advises matching the original connector and using replacement wattage equal to or greater than the original; a 65W label alone does not establish compatibility with every laptop.
If you want to use fewer adapters, compare USB Power Delivery support and the output available to each device when multiple ports are in use. Samsung and Belkin provide examples of charging conditions that depend on the device, cable or port combination.
Consider where devices and leads will sit, how the connected load relates to an extension lead’s rating, and whether the product and seller information can be checked. Scottish Fire and Rescue Service advises against charging while asleep or away from home.
For relevant mains-powered equipment, GOV.UK guidance distinguishes the applicable marking routes for Great Britain and Northern Ireland. A marking alone does not prove that an individual item is safe; check the exact model, seller and manufacturer information as well.
| Concern | What to check when buying | Who this matters to |
|---|---|---|
| Product and seller provenance | Compare the exact model, seller and manufacturer details with the maker’s information; check relevant markings and product recalls. | If I want to check who made and supplied an adapter before ordering, provenance comes first; around 29% of consumers prioritise verifiable product and seller information. |
| Device compatibility | Check the device’s connector, specified power and supported charging mode; for multiport chargers, check each port’s output when used together. | When replacing a laptop adapter or sharing a charger, I need the output and connection to match my devices; around 29% of consumers put device compatibility first. |
| Cable capability | Match the cable’s connector and documented power rating to the intended charger and device; check the device maker’s guidance for specific fast-charging modes. | If my adapter and device are already suitable, I still need a cable rated for that setup; around 18% of consumers make cable capability their primary concern. |
| Charging location and socket load | Check an extension lead’s marked current rating against the connected load, avoid connecting extension leads to one another, and consider the charging location. | When choosing where to charge at home, I want to avoid relying on an overloaded lead or placing equipment beside a sleeping area or exit; around 24% of consumers prioritise the home setup. |
A logo or marketplace listing does not, by itself, establish that the specific item is genuine or safe. In a 2026 investigation, Which? reported that nine of 15 USB chargers it bought from seven online marketplaces failed its electrical-safety assessment; those selected products are not a failure rate for all marketplace chargers.
Compare the exact model and seller with manufacturer information, check applicable markings and contact details, and search the current product recall information.
A charger’s maximum output may not be available to every device or when several ports are occupied. Belkin specifies up to 65W from one port on its WCH013myBK and 45W plus 20W when both ports are used; the device and cable also affect the charging arrangement.
Match the device’s requirements to the charger’s output for the port combination you intend to use, then check the cable’s documented rating.
Surge protection does not resolve overloading, charger incompatibility or an unsuitable charging location. These are separate considerations.
Check the lead’s marked rating against the combined load, do not connect extension leads to one another, and choose an uncovered charging location away from an exit route.

For a home charging spot that needs additional socket access; check the connected load and keep to the lead’s stated use limitations.
Four sockets; 2-metre lead; surge protected.
Do not connect this extension lead to another extension lead or cable reel.
No image available
For a compatible USB-C device when its specified charging requirements match the charger’s stated output.
USB-C charger; 30W stated in the product name.
No image available
For a compatible USB-C charging setup that requires a cable with the stated power capability; check the device and adapter requirements too.
USB-C charge cable; 240W stated in the product name; 2m.
No image available
For a compatible USB-C device or a DC-input setup only when the connector and charging requirements match.
67W stated in the product name; six types of DC connector stated in the product name.
No image available
For charging several compatible devices from one adapter when its port arrangement and output meet each device’s requirements.
130W stated in the product name; four ports stated in the product name.
No. For relevant electrical goods, a marking represents a conformity claim, not an independent guarantee about the specific item. GOV.UK guidance sets out different applicable marking routes for Great Britain and Northern Ireland. Check the seller, manufacturer information, instructions, exact model and product recall information as well.
A compatible device and adapter can use a supported charging mode, but a higher number on the adapter does not guarantee the phone’s fastest charging mode. Check your exact model’s connector and supported mode, along with the maker’s cable guidance; requirements can differ between device models.
Choose an uncovered location that does not obstruct an exit, and avoid charging while asleep or away, as Scottish Fire and Rescue Service advises. London Fire Brigade also advises against covering chargers or charging devices. Stop using visibly damaged equipment; the Scottish service lists unusual heat, swelling, smoke or unusual sounds among battery warning signs.
No, not by itself. Electrical Safety First advises checking the lead’s marked current rating against the combined appliance load, using one extension device per wall socket and never connecting extension leads to one another. Surge protection addresses a different issue from overloading.
Keep the order details and identify the seller and product model. GOV.UK guidance explains that goods that are faulty, not as described or do not do what they are supposed to do qualify for a refund under the applicable rules; some distance purchases also have a cancellation right, subject to its conditions. Check the exact model in the Office for Product Safety and Standards recall information and follow any relevant notice.
