USB hubs provide extra USB ports for easy connection of all your USB devices. Place a large hub on your desk for easy access to a number of ports when you need them. A versatile Ethernet/USB adapter hub converts Ethernet power through a USB port, while an AC/USB adapter plugs into a standard outlet. Choose energy-saving hubs to minimize your electricity usage. Accessible power switches keep ports from pulling from the power supply when they’re not in use, and LED lights let you know if your hub is off or on, providing you with a convenient reminder to turn it off between uses.
