FAQs
What is the maximum total amperage for the USB ports?
The two USB ports share a total output of 5V DC 2.4A. This means the total current is divided between the two ports, so charging may be slower if two high-demand devices are connected simultaneously.
Do I need a special type of backbox for this socket?
Yes, a minimum mounting box depth of 25-35mm is recommended, depending on the wiring conditions. Ensure your existing backbox meets this requirement or is replaced if necessary.
Can I use this socket outdoors?
No, this socket has an IP20 rating, meaning it is designed for indoor use only and offers no protection against water.
What is the warranty period for this product?
Please refer to the manufacturer's warranty documentation for specific details regarding the warranty period and terms for this product.
How should I clean the screwless faceplate?
Clean the faceplate with a soft, damp cloth. Avoid using abrasive cleaners or solvents, as they can damage the matt black finish.
Are the USB ports suitable for fast charging?
The shared 2.4A output is suitable for standard charging of most smartphones and tablets. For devices that require higher wattage fast charging, a dedicated charger might be more appropriate.
What does 'screwless' mean in the product description?
The 'screwless' design means that the front faceplate of the socket does not have visible screws. It typically clips onto a securely mounted inner frame, providing a cleaner, more modern aesthetic.
Troubleshooting
USB ports not charging devices.
Ensure the device is properly plugged into the USB port and that a certified USB cable is being used. Check that the main sockets are switched on. The total USB output is shared; if two high-demand devices are connected, charging may be slow or appear non-functional for one. Verify that the unit is correctly wired by a qualified electrician.
Switched sockets are not providing power.
Check that the appliance plugged into the socket is functional. Ensure the individual socket switch is in the 'on' position. Verify the main circuit breaker or fuse for the circuit is not tripped. If power is still absent, consult a qualified electrician to check the wiring.
Unit feels loose or is not flush with the wall.
Ensure the mounting box is securely fixed to the wall and that the product's backplate is properly screwed into the mounting box. The screwless faceplate should then clip securely into place. If issues persist, re-check mounting box depth and wiring clearance.
