Combines the power from 2 USB ports for a USB device with a higher energy requirement. This can be operated at last peripheral devices without additional AC adapter to the USB port, requiring more than 500 mA. For example, external hard drives, Cooler Pads, GPS receivers, and more. Also great on the notebook.
- Connections: 1x USB plug A (data + power), 1x USB plug A (power only), 1x USB B connector
- Requires 2 free USB ports
