The four port AXAGON HUE-S2B USB 3.0 hub with optional external power and fast charging support on all ports.A lightweight small hub with elegant, matte plastic body connects quickly and easily up to four USB devices to your PC at one time.A great advantage is the possibility of external power supply from any mobile device charger with a micro USB connector. The unused charger thus makes this USB hub a fast-charging hub for free.Mobile phones, tablets, power banks and other devices can be charged up to 2A (depends on the charger used) in any hub port thanks to the USB Battery Charging 1.2 support.Supports charging of iPad tablets even without auxiliary power supply with approx. 1A (iPad mostly cannot be charged directly from the USB 3.0 ports on the PC).It can even handle permanent connection of several external disks without external hub power. When external power supply is connected, you can even work with three external disks at one time.The USB ports located across the hub body with sufficient spacing ensure seamless direct connection of large USB devices.A permanently attached USB cable with a sufficient length of 30 cm is ideal for use with laptops.It can also work as a separate charging hub and charge the USB devices from the power adapter even when the PC is turned off or disconnected.
