Four-port USB-C charger

This 40-watt wall charger provides four USB-C ports for charging several devices at once. It suits households or offices where multiple smartphones, tablets or other USB-C gadgets need power from a single socket. The compact cube form factor keeps desk or travel bag space tidy. Each port negotiates the optimal current for the connected device.

Total 40-watt budget

The adapter delivers up to 40 watts shared across all four ports, so charging four phones together is practical while a tablet plus two phones will draw the full budget. When every port is in use the per-port power drops, so very large laptops or power-hungry tablets will charge more slowly than with a dedicated brick. Single-port devices can still receive the full 40 watts when nothing else is plugged in.

Power Delivery fast charging

The charger uses Power Delivery to provide high-speed charging for compatible iPhone and Galaxy models listed in the specifications. Devices that do not support Power Delivery will charge at standard USB rates instead. Buyers whose gear relies on proprietary fast-charge protocols not covered by Power Delivery should check compatibility before purchase.
