Extension Socket 2 Outlet, USB Power Strip with Multiple Function 3 meter Cable Extension Board

Core Components & Features

AC Electrical Outlets: Standard 3-pin or universal plug sockets (typically 2 to 6 bays) that deliver line voltage (110V–240V AC) for laptops, monitors, appliances, or lamps.

Integrated USB Charging Ports: Built-in USB-A and modern USB-C Power Delivery (PD) ports that step down line voltage internally to 5V–20V DC, allowing direct plug-in for smartphones, tablets, and wearables.

Internal Transformer / Circuitry: Converts high-voltage AC to low-voltage DC automatically, incorporating smart-charging ICs to negotiate the maximum safe current for connected mobile devices.

Safety & Protection Mechanisms:

Surge Protection: MOV (Metal Oxide Varistor) components to absorb sudden voltage spikes.

Overload Switch & Circuit Breaker: Resets or trips if total power draw exceeds the strip's rating (typically 2500W to 3650W).

Fire-Retardant Casing: Constructed from ABS or polycarbonate plastics rated to withstand temperatures up to 750∘C750^\circ\text{C}750∘C.
