DANGER
Always isolate power before touching wiring. USB sockets are wired to mains – installation must be done by a qualified electrician.
Understanding Amperage: Fast vs Standard
USB sockets supply power at 5V. The amperage (A) determines how fast devices charge. Higher amps = faster charging (up to what the device can accept).
- Standard (1A–2.1A): Fine for older phones, small tablets, and low-power devices. Charging will be slower.
- Fast charging (2.4A–3.1A per port): Better for modern phones and tablets. Many phones support Quick Charge or similar at 2.4A+.
- USB-C PD (Power Delivery): For laptops and high-power devices. Look for sockets with USB-C and PD ratings (e.g. 30W, 45W).
Where to Use What
- Bedside / living room: 2.1A or 2.4A per port is usually enough. Two ports let you charge phone + tablet.
- Kitchen / desk: Consider 3.1A or USB-C sockets if you charge laptops or power-hungry devices.
- Shared sockets: If two devices plug in at once, each port may share the total. Check "total output" – e.g. 3.1A total = ~1.5A each when both used.
USB-A vs USB-C
Newer sockets offer both USB-A and USB-C. USB-C is the future for phones and laptops. For flexibility, choose dual-port sockets (USB-A + USB-C) with at least 2.4A per port. Laptop charging needs USB-C PD.
