Customer Reviews

  • One of the Best Hubs Out There. I am not disappointed.Verified PurchaseThis review is from: Anker® AH231 USB Hub with 9 USB 3.0 Data Ports + 1 Smart Charging Port (5V / 2.1A)with 12V 5A Power Adapter
  • I bought this after googling best USB hub and reading a review on gizmodo. I am not disappointed. Just to push the thing I connected 4 1TB external hard drives and cross-copied videos among them, and my firewire connected Drobo. Not a single drive dropped.I do have some issues with some ports not lighting, i.e. if I plug an extension in port 2 then skip to port 8, port 8 won't light up. But if I connect them all sequentially then it all starts to work. I currently have an RF usb wireless mouse connected to port 1 which lights and works fine contrary to what some reviews say. To work around my issue above I try to connect all the usb devices next to each other.I'm using this on my MBP with a USB 2.0 port. It replaced my old 4 port hub and I can see the Anker lasting quite awhile. Compared to my older hub, the power brick on this thing is huge! That's a good thing cause at least I know the hub will have enough power to keep all my drives alive when connected.I'm glad I got the 9 USB data port over the lower one cause now I have a future proof hub. If you're not sure if this device is right, well, just go for it. For the money, its a pretty good value.

  • It's a great product, nice and compact, well built, pretty solid look and feel. Has a quick-charge slot for just delivering power to a USB device, which is nice. Only issue is that my laptops do not "see" my USB3 HDD when connected through this hub. The manual that came with the hub says some USB3 HDDs require direct connection to the PC. USB2 flash drives and HDDs work fine, but not the USB3 HDD. Disappointing, but not enough to return the hub.

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.

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:

The 9 port hub will be able to transfer data from all 7 GoPros but whether it will charge or not depends on the input requirements of the GoPro. The max output of the ports is 0.9A.

The 7 port hub's ports are all able to provide much higher power so they should definitely be able to charge the GoPros as well as data transfer.

It may work for one or two very low power devices but we would recommend always having the power adapter plugged in.

Without it the hub may not work consistently and could become unstable during data transfer.

Does it work with Anker Astro pro 2
Hi,I own an anker astro pro 2 external battery and i am interested in knowing whether this 9 port hub can work with the external battery for the charging port? Also is it possible to connect the hub to the output DC slot of the powerbank (12/16/19 volts) and use the hub to charge a maximum of 3 devices like ipad,note 2,canon camera (5 W) at the same time?Thanks 
Replies(2) Collapse Report as spam May 22, 2014 at 12:09 AM

You should be able to power the hub from the battery but please note that there is only one designated charging port on the hub and the rest are purely data transfer so will not supply a particularly high output for charging other devices.

If you're looking to charge multiple devices at the same time from one USB hub I would consider looking at our 40W 5 Port charger.

Tiny, Many ASIC miners don't fit.

This, or maybe a previous version, was touted as the Holy Grail of USB hubs for bitcoin mining, but Red Fury miners do not fit in it unless I skip sockets, wasting half of them. Pictures online suggested it was a larger hub with plenty of space between the ports. I am terribly disappointed.
