If I plug this into the front of my computer and let it dangle will it fall out?

I had the same problem when I have gotten my USB, what I did to fix the Problem was” I put a book I didn't need any more .in the back of the computer. Then I laid the lax part of the USB on the book. Had mine there for years, no problems yet.

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

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.

How long is the connection cable? Does it require AC adapter?

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.

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?

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.
