  • My Favorite USB Hub... I have two!
  • I love the Anker USB Hubs. For starters, the design is perfect; the flat layout is well balanced and a vast improvement over vertical USB hubs that always seem to flop around depending on the cables attached. No matter what I have plugged into these, they always stay flat on the desk. This also makes plugging cables and flash drives in and unplugging them easier as well.With 9 ports, you might worry does this unit have the juice to handle it all with bus powered hard drives in the mix... yes it does. I have had zero issues with all the devices plugged into the Anker USB Hub. And, the charging port is a nice plus.On top of all that, they have a nice clean design as well.

  • My desktop has a couple hard-to-reach USB-3 ports in the back. I've got this bad boy sitting up on my desk (a little bit of tape on the bottom side to keep from sliding/moving).I routinely use this hub for USB memory sticks, a USB-3 external hard drive, and of course recharging a couple cell phones.With its own power this hub seems (to me) to provide a noticeable boost in performance for all of my USB-2/USB-3 memory sticks, ie, read/write speeds routinely hit at/above each device's rated max speeds.

  • Good hub.
  • I own two of these and am generally pleased with their performance. The latest one lasted about 2 months before ports #7, 8, and 9 failed. I returned it for a full refund, which was handled promptly. The older one, about 4 months, is performing flawlessly.

Customer FAQ

Q1.  Will the current requirement of my devices influence Anker hub's performance?
For maximum performance, connected devices should not exceed the combined current of the output of hub. Otherwise, output current may become unstable or disconnect entirely. See some commonly used devices' general requirements below:
250G Hard drive – 600mA
4G Flash drive – 100mA
64G SSD – 400mA
100M Network adapter – 500mA
Keyboards and mice and other peripheral devices – 100mA (or less)

The ratings above are estimates only. Please check your specific device's ratings before connecting to the hub.
Q2.  When my hub is connected through the ports on my Apple expansion card it fails to be recognised, why is this?
Mac expansion cards don’t tend to support non-storage devices (more info is available from your expansion card manufacturer's websites). It is recommended that you plug hubs into the Mac’s built in USB ports.
Q3.  My Western Digital hard drive cannot be recognized by your hub? How to fix it?
This could be to do with the firmware on your Western Digital hard drive. Try installing new firmware, downloadable from the Western Digital website.
Q4.  Why does Apple SuperDrive not work with your Anker hub?
Apple have addressed this issue and said that SuperDrive is only designed to work with USB ports on selected Apple computers. It is not recommended for use with USB hubs. (See Apple support article
Q5.  Why do my wireless mouse/keyboard not work closely with Anker USB 3.0 hub?
2.4Ghz wireless devices may have frequency interference issues with USB 3.0 ports so we recommend using a USB 2.0 hub instead.
Q6.  Do you have any driver for the hub?
Our Anker Hubs are plug-and-play so there's no need for extra drivers, but we do recommend updating your USB controller’s drivers and firmware to the latest version. This ensures a smooth experience using any USB devices. To do this you should identify the brand of your USB controller then search online, or contact your PC/motherboard supplier directly.
Q7.  Why is the transfer rate so much slower than the 5Gbps promoted?
The USB 3.0 transfer rate is 5Gbps and has a theoretical transfer speed of 500MB/s which is about 8 times faster than the USB 2.0 transfer rate of 480Mb/s with theoretical transfer speed of 60MB/s.
There are numerous variables that will affect USB transfer rate including data source and destination and file type. With all reasonable usage environments taken into account USB 3.0 can achieve average transfer speeds about 3 times faster than that of USB 2.0.
Q8.  Devices are not being identified by my computer when connected to the USB hub, but they are being identified when connected directly to the computer. Why?
This problem may be the result of one of the following:
    a. Insufficient power supply. Please connect the USB hub to a power source.
    b. Compatibility issues between the motherboard and system. Please try refreshing the BIOS in the motherboard.
    c. Incorrect insertion or unplugging. Do not unplug the device when transferring data in order to avoid damaging the chipset.
    d. Improper driver installation. Under “Device Manager”, go to “Other Devices” and select “Universal Serial Bus Controllers”. If there are any yellow question or exclamation marks visible, uninstall the driver in “Device Manager”, then restart your computer. The driver will be reinstalled automatically.
Q9.  Can I use my own accessories, such as power adapters and data cables, with the USB hub?
The USB 3.0 hub is equipped with its own power adapter and data cable to ensure maximum compatibility. Use of the provided cables and adapters is always recommended. If you have lost the power adapter or data cable, please make sure the specifications of any accessory you intend to use correspond with those provided. To ensure stable performance, the length of the data cable should not exceed 1m.
Q10.  Why can’t devices be charged at 900mA (max for a USB 3.0 port) when a USB 3.0 port is not in use for data transfer?
The devices attached will firstly detect if the port is a charging port or a data port and enter a different mode accordingly. When attached to a USB 3.0 port, the device will reserve a 500-600 mA for data transfer (even when not in use) and only leave the rest power for charging.
Q11.  Can I use the USB hub as a standalone charger?
For Anker hubs without a specially-designed charging port, the max output current of the USB ports is 900mA, these ports can transfer data but aren't recommended for charging. Some of our hubs have specially-designed charging ports can reach outputs of up to 2.1A and can charge iPads, iPhones and other smart phones.

Please keep in mind that the charging port can't transfer data. Charging ports and data-transfer ports supply different voltages which a device will recognise when it is plugged in. The device will enter the mode that the USB port's voltage corresponds to.
Q12.  Why is the computer failing to come out of Sleep Mode when the USB hub is connected?
This problem may be the result of one of the following:
    a. Improper power-saving settings. Right-click “My Computer”, select “Attributes”, then “Hardware”, followed by “Device Manager”. Double-click “Universal Serial Bus Controllers”, right-click “USB Root Hub”, click “Attributes”, then “Power Management”. Unmark “Allow computer to close the device to save power”, click “Yes ”, and then restart the computer.
    b. The computer can’t start because it can’t read system files. This occurs when the BIOS is set to “Start the Computer from the USB Device”. In order to solve this, change the setting to “Start the Computer from the Hard Disk”.
    c. For Mac users, please uncheck the box "Put the hard disks to sleep when possible" under Energy Saver.
Q13.  A surge warning appears on the screen when the USB hub is connected to the computer. Why is this happening?
When the input current requirement of a connected device is higher than the output current of the USB port, a surge warning may appear. Connect the USB hub to a power source to ensure sufficient power supply.
If the problem persists, please check to make sure the USB driver is installed properly, or click the USB icon on the taskbar and select “Reset” to make sure the USB device is being identified correctly.
Q14.  The hub keeps suddenly disconnecting from the device while transferring data. Why is this happening?
If this problem is occurring with properly-installed devices, it is usually due to insufficient power supply. When the hub is transferring data - especially large amounts - make sure it is connected to a power source. In addition, we recommend connecting the hub to your computer with the cable provided. If not, please make sure the cable length is less than 1m, so as to ensure stable data transfer.
Q15.  Why is my USB 3.0 device being read as a USB 2.0 device when connected to the hub?
This problem may be the result of one of the following:
    a. Insufficient power supply from the USB hub. Please connect the USB hub to a power source.
    b. Insufficient power supply from the computer’s USB port. Please connect the USB hub to the USB port positioned on the back of the frame, instead of on the front, to ensure sufficient power supply.
    c. The device is being plugged in too slowly. As a result of the USB 3.0 interface design, the system will recognize devices as USB 2.0 when they are plugged in too slowly, or section by section.

Seagate Drive Connectivity Issues
I have 3 Western Digital USB 3.0 and two Seagate 3.0 Drives connected to my Anker 9-Port USB 3.0 hub.  After upgrading to Windows 8.1 my Seagate drivers no longer connect through the hub, but the Western Digital drives do.  If I connect the Seagate drives directly to the computer, they come up fine.  Any idea what's going on?

power ipad etc and plug into wall
Hi,I am looking for a port that I can plug two blackberrys,two ipads an ipod, a speaker and bluetooth keyboards so that they can all charge at the same time and can be plugged into a wall.  Will the Anker 3.0 usb 9 port do this?  Thanks

This product is mostly used for plugging lots of things into a computer. So this won't charge devices at high speeds. I would suggest the Anker 40W 5 Port USB Charger. Link:
Reply Report as spam Aug 15, 2014 at 2:45 PM

The USB hubs are actually not designed to be used as chargers, they are data transfer ports with a max output of 0.9A so they won't be able to charge devices like iPads very quickly.

We'd suggest our 5 port charger with Power IQ, that'll charge 5 of them at the same time and watch this space for more chargers with more ports very soon!

Lose Connection WD Elements Hard Drive
Losing Connection with WD Elements Portable Hard DriveThis is the first day I have used this Anker 9 port powered hub.I have connected a wired mouse & keyboard, as well as an Imation flash drive and a WD Elements Portable Hard Drive (2T). The HD is a backup drive and backs up files as they are saved and does a full User BU 2 X a week.The drive is constantly losing connection when using the Anker 9 port powered hub. This never happened when the HD was connected directly to my PC. My PC which is a Lenovo Thinkpad  --with 2 x 3.0 ports -- hence the necessity for a hub.- I am using the port closest to the computer.- The Firmware of the HD is up to date.- I do not lose connection of the mouse or keyboard- I do not lose connection when the HD is directly connected to the PCAt the end of the day the integrity of my data is more important than speed, and I am concerned that it will lose connection at some point of a long file transfer such as a disk image or back up will corrupt the integrity of the data.  If it means connecting the HD to the 2nd port then the convenience of theAnker device is not needed. I have older USB hubs I could use for the mouse and keyboard.Do you have any suggestions to sort this out? PS I also purchased the Anker 4 Port Compact USB unpowered hub for when I am on the road / travelling and I am also having the same problem.

Since you are having the problem with 2 hubs that does indicate the problem doesn't lie with the hub itself.

The problem may be down to insufficient power supply. Please make sure you're using a short cable between your computer and the hub and that it is plugged into a power supply.

If you're still having problems then give our customer service guys a shout at and let them know. They'll be able to help you further.

Thank you for your response.I have also tried going into Device Manager >>> Universal Serial Bus controllers >>> USB 3.0 Hub(s) &  Intel(R) USB 3.0 Root Hub  >>> Power Management >>> Allow the computer to turn of this device to save power (check) without any benefit.FYI - I am only using the Anker supplled cables and powersupply -- on the 4 port hub the cable it is hard wired, so no option to use anything else. - I don't have any problems using the HD directly with my PC 3.0 port or on other 2.0 USB hubs such as the Belkin 7 port hub or the Toshiba Docking Station, however both a 2.0. I am only having the connection issue with Anker hubs, both powered and unpowered, and using only while the Anker supplied connections, so while both hubs may be functioning there is some sort of incompatability issue between Anker 3.0 products and my computer.Thanks again, I will contact support:
