Connecting the power supply— ability to connect an external power supply to a device with a USB splitter function (card reader or hub). Additional external power is useful if the devices connected via a splitter consume a lot of energy, and the own power coming from the computer's USB port is not enough to ensure their operation. And some of these models can also work as stand-alone chargers for portable electronics, without being connected to a computer.
