Question:	Will the anker 4-port usb 3.0 also support usb 2.0 devices
Answer:	I would say about a foot. With the bar to hold onto it is pretty easy to step up. It is very handy - I originally purchased it to get in and out of the bathtub and it worked very well until I got a tub bench. Now I just use it around the house. Hope this help.
Question:	My external hard drive is a 4 tb . I want to use this to pulg my hard drive and my wireless headphones that use a usb Transmitter. Will this work
Answer:	No, the handle isn't attached. You have to insert it yourself and it is wobbly due to the way it attaches (via two small buttons).

User questions & answers

Question:	What's the performance when. let's say, 4 pendrives are connected in? Do you experience any troubles moving data between them or to the computer
Answer:	As a result of some files transferring test, I think this item has not trouble some. However, I found one of trouble on USB memory stick. Here I show you my test result. I use Mac mini 2012 late model with MT Lion, Kingston USB 2.0 Memory Stick 16GB, 1TB Micronet Fantom Drive (HDD) and Sabrent 4-port USB 2.0 Hub.Transfer Speed Test result (4 files total 5.19GB): 1. Direct USB port connection (HDD)--32.44mb/s. 2. Use USB Hub (HDD)--34.83mb/s. 3. Direct USB port connection (Memory stick)--3.74mb/s. 4. Use USB Hub (Memory stick--3.65mb/s. In my conclusion, USB stick is much much slower than HDD. Sabrent 4-port USB 2.0 Hub has not trouble some. USB memory stick has a trouble to transfer a large size file. I need more test, but I found a large size file can not copy into the memory stick with error message "...can't be copied because it is too large for..." or "...can't copy because there is not enough space to copy...". However, when I got this message, it was empty on memory stick. I could copy 1gb, 2gb, 4.21gb files but cannot copy 8.75gb and 15.04gb files. I need to find out from the what size cannot copy.
Question:	can i connect this device to a wall plug and charge my iPhone/apple products or does it have to be connected to a computer to charge my apple products
Answer:	This is a UN-powered USB hub and is intended for devices which do not draw more than minute amounts of power from the USB port such as printers, thumbdrives, memory card readers. USB 2.0 specs state the maximum power to be drawn off a USB port is 500mA (0.5 Amps). A typical smartphone charger provides twice as much power -- 1000mA (1.0 Amp). Tablet chargers provide even more -- 1.8A to 2.1A.If you want to charge a phone, tablet, portable battery pack, or power a USB-powered device, you need to get a POWERED USB hub. The easiest way to identify one is that it comes with an AC power adapter which must be plugged-into the USB hub.
Question:	How long is the connection cable? Does it require AC adapter
Answer:	Maybe they have changed this device recently but the cable on my hub is 10" long. The power is supplied by the source USB to which the hub is connected. You will only get out what you put in. As such it will not charge power hungry devices like an iPad when connected to a computer but will when connected to a wall charger.
Question:	If I plug this into the front of my computer and let it dangle will it fall out
Answer:	I don't think it will fall out. I have mine plugged into the back of my computer, it just hangs there, seems pretty secure. I've also used it on my Xbox to connect 4 controllers and it didn't fall out.

User questions & answers

Question:	I have 2 external hard drives: 1 is 500 GB, 1 is 2 TB. Both have their own power cords. Will they work with this hub
Answer:	yes they will, I have a 3 tb WD, a 2 tb Fatom,and a 1tb HP they all work fine, and and any thumb drive that I plug in syncs right up.Some of the thumb drives are usb 2.0 , no problem
Question:	What is the recommended ac adapter to use with this
Answer:	JTJ said he didn't have a power jack. Either there is more than one version or he has one but didn't find it. It would be easy to miss. It's next to the USB cable. For basic devices, like a mouse, keyboard, etc, you do not need a power supply. The computer will power them, but the current the computer will supply is limited. If you plan to charge a smart phone, tablet, or something like that you should make the adapter part of your plans.(http://www.amazon.com/Sabrent-100V-240V-Adapter-Support-PS-5V4A/dp/B00MRGKPH8 )
Question:	If I plug this into a 2.0 USB port on my CPU, will I still get the benefit of Sabrent's 3.0 speed? Or is it about time I update my motherboard? Thanks
Answer:	@T. Freese: No. The nature of USB is that devices can not communicate among themselves. All communication goes through the host computer. So a pair of 3.0 devices sharing a hub attached to a 2.0 computer will communicate at 2.0 speeds.
Question:	Does the fact that each has a switch mean that you can just turn each of them off without doing "safely remove" or "eject" devices
Answer:	The reason that you use the Windows Option to safely remove the drive is so that windows has a chance to close any File Pointer that is in use. If this is not done, then there is a chance that the file(s) will be locked and/or corrupted the next time the drive is accessed.So. It is recommended that you safely remove the drive before you hit that power switch on the hub.I have this hub and use it to access 1 4TB drive, 2 5TB drives and 1 8TB drive. That is a LOT of data to loose just because I got lazy.The one reason to have switches on a hub is so that you can have the drives OFF when not in use. This will save some life on the hard drive.Lance
