  • Another solid product from Anker...
  • Nice. Not unattractive...I like it. Had to double sticky tape it to the table or it would move around, so maybe not heavy enough, but I might have taped it down anyway.Didn't notice really blistering speeds, but I haven't tested it enough. I will update this review when I have.Holy Cow Batman, that's a bright freaking light. It is blinding even if you're not looking right at it. I put a piece of duct tape over it and its still bright.Over all, I am happy. Anker seems to make great products.

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.  Can I use the USB hub as a standalone charger?
The output current of the USB port is 900mA max. If you are using the hub to supply power, please make sure the input current does not exceed 900mA. The hub can’t supply enough power to iPhones, iPads or any other smart phones.
Q9.  The 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 is this happening?
This problem may be the result of one of the following:
    a. Compatibility between the motherboard and system. Please try refreshing the BIOS in the motherboard.
    b. Incorrect insertion or unplugging. Do not unplug the device when transferring data in order to avoid damaging the chipset.
    c. Improper driver installation. In “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.

Support For Portable Hard Drives

Does this Hub have the capablity to support two simple external portable hard drives?

Replies(5) Collapse Report as spam Mar 27, 2014 at 8:16 PM

It can but it might not work super well during full load. 


It also depends on the power draw of your two external hard drives.

Reply Report as spam Mar 27, 2014 at 8:25 PM

Keeping in mind Ankers's info, note that external drives can be either bus powered or have their own power supply. I have successfully used both types with Anker hub. That being said, I would not recommend using any external HD with any hub on a constant basis.

This depends on the power requirements of your hard drives. This hub can provide 0.9A per port so if your hard drives require more than that then they might struggle. Be sure to check your hard drives' technical data!

This is very helpful, thank you.

Reply Report as spam Mar 28, 2014 at 4:29 AM

Most external hard drives draw close to 900mA when in load so if you have 2 connected, one of them might not work. 

As you can only deliver a total of 0.9A since you're still connecting both connections on the hub to 1 USB 3 port on your computer

As nice looking as this is, the Anker AH430 is more contemporary and I like the way the slots are arranged. My need is for a hub with only one port (all of the other needs are in an Anker multi-port hub strip mounted just offside of my monitor. The one port is within hands reach to plug in one of my several digital cameras and sometimes a convenient pocket thumb drive. I love the look of the Anker AH430 but wish it was half the size with 2 ports max.

Wow Beautiful Design

With all the awesome Anker USB hubs coming out recently, I wanted to see some of Anker's older offering and I stumbled upon this! This is amazing simple and beautifully designed. Now I can understand why all of Anker's products look so great. They had great design since early on and have only been growing and becoming even better at it  .

I don't mind the logos as they're usually covered for me or I remove them myself. It's really an issue with all products, you're going to have a logo no matter what unless you make it yourself/ do something to customize it yourself. If you really care about it, you can remove them yourself but it only works on certain materials

I agree. Simple design and to back it up, simple packaging. I've found that a nice presentation when I've opened their stuff.

My desk looks like the Anker Store Showroom. Much as I like Anker I have tHe same negative as I do about many, but not all, brands which is the bold logo facing the user. I already bought the product, I don't need an ad facing me all the time. Worst offenders are TV and monitor manufs who paint their specs on the bezel.

Quote From TechToyWizard: Hm luckily I've never had any devices that over did their logo and printing. My monitor only has LG written on it in the front bezel and it is very grey and blends in well with the monitor. I think I've just been unconsciously buying beautiful devices without much manufacturer "bloat" That's exactly how I like my phones too. Remove all carrier bloatware apps

We're on the same page IT. I just consciously looked around an nothing with a subtle logo bothers me. It's more the spec hype some companies plaster all over their product.
Reply Report as spam Mar 16, 2014 at 12:43 PM
IT, note I referred to some but not all brands. Certainly some overdo it and some are very subtle and low-key. Most consumer products have logos ... Ford, Toyota, Nikon, etc, etc. That's not really the point if they are subtle. I'll go into Anker's fantastic solution to this issue in a future post but I am so happy they are addressing what I proper logo should look like. And I actually replaced another brand's monitor because the entire bottom bezel was printed with every possible spec and no it was not removable.

Why Anker
Memo to people considering where to buy their high tech accessories ... I buy a lot of add-ons and there are is a bewildering number of products out there. I don't abuse it but sometimes I have what I consider to be valid questions. Anker is one of the very few accessory companies that will take the time to answer my questions. 90% of the time online sellers simply ignore any attempt to contact them. No only does Anker answer but they are unfailingly courteous and give a personal reply, not a stock cut & paste machine generated response (like how they answered my questions about this product). This is so important to me that I always check Anker first before I buy any accessory.

Primarily for flash drives?
The usage notes are a bit vague. I have a very similar 2.0 hub that I use exclusively for flash drives and to download digital pics from my cameras. Would you say this is adequate for such purposes? None of those devices are USB 3.0 but my main reason for purchasing this would be because it is attractive.

Nothing too extreme, it simply won't work or the connection will be unstable.
Reply Report as spam Dec 1, 2013 at 3:12 AM
One of the points above states: "This thing may be small, but it's still a fully-functional hub." so you could use it for any USB device - a flash drive, external hard drive, transferring photos from a digital camera, etc.
Reply Report as spam Nov 27, 2013 at 11:40 AM
Thanks. Further down Anker states "For stable operation, devices connected to this hub should not exceed a combined current of 5V 900mA" so I read that as I could not use any USB device, only those that don't exceed 5V 900mA. It would be nice to have an example of what devices would be considered too much of a draw.
Reply Report as spam Nov 27, 2013 at 2:07 PM
Ah! I hadn't noticed that part. Sounds like they are basically saying don't use this for charging your devices via this hub as most phones and certainly tablets all take 1 Amp or more.
Reply Report as spam Nov 27, 2013 at 5:50 PM
Definitely agree with you, it should not be used for charging devices (not even sure I could do that). What I'm thinking is more along the lines of plugging in desktop portable devices temporarily such as portable hard drives, portable 4x6 printer, portable scanner, portable label printers, etc. I'm not even sure how much current devices like that draw.
Reply Report as spam Nov 27, 2013 at 6:14 PM
Sorry about the confusion, we'll add some examples to illustrate. Basically, USB devices that require a lot of power like large-sized external hard drives may not work because this hub does not have a dedicated power source. Flash drives, mice, keyboards, cameras will all work great.
Reply Report as spam Nov 28, 2013 at 8:39 PM
Thanks Anker Team. What would be the likely result of using such a device? Would it blow the device out, blow the hub out or would the device simply not work for lack of adequate power? Thanks!

Works very well and looks great!
This hub works extremely well with my Windows 7 PC and laptop. No installation required, just plug and play. Fast transfer rates using both USB 2.0 and USB 3.0 - the latter is lightning fast. The product also looks great, a very sleek sloped wedge with a circular base, it sits well on any flat surface. Highly recommended.
