Who knows that the usb hub can be charged?

With the popularity of computers, more and more people use mobile phone charging cable to connect to the computer for charging. Many times, when we charge, we find that the battery is getting less and less, but we don't know what to do! So, can the usb hub be charged ? Together knowledge about usb hub under the understanding of it!

Can the usb hub be charged? The USB hub is also called USB Hub, a device that can expand a USB interface into multiple (usually four) and can make these interfaces use simultaneously.

USB Hub, which can be connected to computer desk lamps, computer fans, MP3, USB flash drives, voice recorders, digital cameras, etc., can be extended into a plurality of independent working USB interfaces, each of which can supply up to 500MA.

The mobile hard disk is powered by USB. The mobile hard disk generally uses a notebook hard disk with 0.5A - 1A. The lower the current, the lower the requirement for USB power supply, and vice versa. The USB Hub does not have its own power supply. It borrows 5V of the motherboard USB. You will know. I don't recognize that the power supply is insufficient. You can use the mobile hard disk directly on the motherboard. You can try to use a hard disk with a small working current, and then buy a USB Hub for a good quality notebook. The problem is solved by more than half. VIA released the world's first USB 3.0 Hub controller, VIA Labs, Inc. of IA Group today announced the launch of the world's first Hub controller "VIA VL810" supporting USB 3.0, using a self-developed single-chip design. The VIA VL810 provides an uplink interface and four downlink interfaces, all supporting SuperSpeed USB 3.0 5Gbps, and is also backward compatible with Hi-Speed USB 2.0 480Mbps, Full-Speed USB 1.1 12Mbps, Low-Speed USB 1.0 1.5Mbps. The controller chip is the first to be manufactured in the 80nm COMS process, with lower power consumption, and also supports power management functions, which can enter a low-power and energy-saving state when the connection is idle, and also allow the device to communicate with the main controller for delay communication. 

USB-Hub is just a tool for extending the USB interface. To put it bluntly, it is just an interface extension tool. In fact, the use of USB-Hub only makes it possible to slow down the speed of USB devices, and it is absolutely impossible to get faster. The best way is to connect the USB device directly to the USB port of your computer instead of via USB-Hub. In particular, the mobile hard disk is absolutely not to be easy to use the USB-Hub to connect, which will even damage the life of your mobile hard disk.

The above is about the usb hub and the usb hub can be charged about the knowledge, office workers will no longer have to worry about the phone is not enough.
