Answer Description

A port replicator is designed to connect multiple peripheral devices via a single connection to the laptop and typically includes a power supply to charge the laptop's battery. This is ideal for a user who needs to expand the available ports while also keeping the laptop charged. A USB hub doesn't usually include a power supply to charge the laptop. Thunderbolt cables and wireless dongles do not provide a way to connect multiple peripherals through one connection to the laptop.
