SMUGDESK 48W 4-Port USB Charger Cube Plug White

Four-port 48 W charger

This compact cube delivers up to 48 W across four USB ports, with one port supporting Quick Charge 3.0 and three ports sharing a 5 V 3.1 A maximum output. It suits households or offices where several phones, tablets or small USB devices need charging from a single wall socket. The white finish keeps it discreet on a desk or bedside table. Input voltage spans AC 100-240 V at 50-60 Hz for worldwide use.

Check your devices and socket

Verify that each device you plan to charge uses a standard USB-A cable, as the charger provides only USB-A ports. Confirm the wall outlet can supply AC 100-240 V 50-60 Hz, which covers most domestic supplies. Ensure the combined draw of all connected devices does not exceed the 48 W total budget, otherwise charging speeds will throttle. The unit has no built-in cable, so you must supply your own leads.

Sustained-load behaviour

Built-in protections guard against over-current, over-voltage and short-circuit during prolonged multi-device charging. The intelligent chip continuously matches output to each device, preventing battery stress when several gadgets charge together for hours. Heat dissipation is handled by the compact enclosure without active cooling, so surface temperature rises under full load but remains within safe limits. Performance stays stable as long as the ambient temperature stays within normal indoor ranges.
