What is the different between this and the other 7-port usb 3 hubs you have listed? http://www.amazon.com/Anker&Acirc;&reg;-7-Port-...

The primary difference is the visual design (the Aluminum MacBook one you mentioned, for instance, is designed to have a similar style to other Apple Products). Some of the Anker 7-port USB 3.0 hubs also have dedicated charging ports (so you could charge a phone, tablet, or other USB powered device). This particular model does not have dedicated charging ports - it is simply designed to allow you to connect multiple additional peripherals to your device. I have two of these, one for my office and one for my home office and they both work great. TL;DR - Visual style and dedicated charging ports are the big differences.

Yes, it is only one USB 3.0 port. If you really like this particular model and need a second port, you could get a USB 3 hub.

Per the product description "This 4-Port USB 3.0 Hub will not charge an iPad (it will only sync)." That makes sense. If you want your device to charge or you want to run multiple external hard drives off of a USB hub, you are actually looking for a different product. A powered USB hub is what you are looking for.

I never thought about doing simultaneous transmissions across all the ports on the hub. My guess is it would slow down, because we know that one port affects the others. Anker makes it clear, for example, that if you plug a USB 2.0 device into the unit, any 3.0 devices plugged in will perform at only 2.0 speed. There are multiple inputs, but only one output to your computer. Think of five hoses plugged into a sprinkler -- the water will not come out 5X as fast. That's my best guess, but I'm not an engineer.

The cable is 24 inches.In my case, I can not operate with more than 3 plugs or the device will fail. But, that is three plugs without the power cable.I have not tried it using the power cable, but I suspect it will handle all seven slots well. Most USB hubs of this kind will not work at all unless they are powered using the power cable. I have a Dynex seven-plug and it will not even allow one USB without power.The individual switches are a nice touch, allowing you to eject the USB device without removing it. It also works well with all levels of USB protocols. I am happy with this hub. The cable is 24 inches.In my case, I can not operate with more than 3 plugs or the device will fail.

Hi there Since I have the 4 port USB3.0 ...I have checked that my external hard drives that are powered up by an extension cord are USB2.0 and it works with my USB3.0 port on the USB HUB. I can not see why not it would not work with the 7 USB 3.0 port. I have this USB 3.0 port hub on Windows 7 Ultimate so it will work with windows 7.

I actually bought one that was specifically for Mac so not sure why my review was posted under this product. The one I bought was this one: Unitek USB 3.0 HUB 3 ports usb3+1 charger-only Built-in USB 3.0 hub usb 3.0 mac. It works perfectly.

This one works great with all USB ports. I'm thinking of getting another. Good luck to you.

All I know is this. It is non-powered hub. Works for multiple flash drives *as many as three have worked at the same time for me*, but if you try external hard drives you will run into difficulty because there is insufficient power from a single USB port to run multiple devices that need more power. t

It appears to have two version. The version I received has same USB 3.0+2.0 ports like in the picture. But the DC adapter that mine came with has detachable connector to the USB hub but it only has one output 2.1A which is mini DC connector head. Doesn't use USB cable to charge the USB hub. The DC adapter shown at Amazon has two DC output connectors using USB cable to connect to the USB hub. If you refer the DC adapter shown at Amazon, you may ended up getting a different version like what I received.

My experience was over 2 years ago. Perhaps they are selling a different product (USB3?) compared to the one I purchased (with the incompatibilities). I recommend buying and trying.

I have the 7-port version of this product, and it won't charge an iPad Air faster than your computer's USB port -- despite claiming the charging port is high-power. It is possible that this version (the 4-port hub) does better, but if it doesn't, make sure you return it within Amazon's return window. In my experience, D-Link has no customer service; I wrote to them twice about a problem with my hub, and received no response (it's been months now).

The USB 3.0 standard is .9A per port. So with a 5V, 5A power adapter, you can only connect five bus-powered USB 3.0 devices (.9A x 5 = 4.5A) before running into problems. You have a little more flexibility with USB 2.0 at .5A (can use all ports except the charging port), but if you're going to do that, you might as well buy a USB 2.0 hub and save some money. Anker has a similar product (9 USB 3.0 + 1 charging port) that comes with a 12V, 5A charger. The power adapter is not a wall-wart...it's a brick similar to what laptops use, and it's bigger than the product itself!!! It adequately powers nine USB 3.0 devices and an iPad because of the whole Volts x Amps = Watts thing and some undervolting to allow the 12V adapter to power 5V devices.

The hub overall is limited to 2A (2000mA). 3 of the ports are standard USB 2.0 500mA and are only powered when the host computer is on. One of the ports is marked as a "fast charging port" with 2A and available when a USB host is disconnected, though the specs state that this delivers only 500mA when a USB host is connected. I haven't measured this with a multimeter but based on what I've seen using the fast charging port to power a RaspberryPi (which is also the USB host) I believe the charging port is not limited below 2A when a host system is connected, but instead, all four ports are limited to the 2A maximum with the other 3 ports limited to 500mA each.

I bought a plugable USB 2.0 4 port hub and charger. It didn't work as I had hoped. For keyboards, a mouse, and a flash drive I need a OTG cable. The hub charges my Nexus 7 tablet and allows my computer to swap files with it.

My "docking station" has a total of 6 USB ports. I can't determine which are USB2 vs USB3.
