A 10 port USB hub might be the "Holy Grail" of tools to connect multiple USB devices.
As others have commented, however, the device feels cheaply made.
USB cables do not seat fully.
Most importantly, assess your power/charging needs before purchasing.
Many reviewers comment on the ability/inability of their USB devices to charge while plugged into various USB hubs. Some of this may be traced to the power supply for the hub. My personal experience is that, depending on the USB hub I'm using, if I'm trying to run a USB cooling fan, charge my iPhone and Blackberry at the same time (while other USB devices are attached), I will get an error message stating power is inadequate, or one of my devices simply won't charge.
Almost all (all?) USB hubs are powered by devices whose DC output is 5V. Most manufacturers do no list on their web site how many amps are provided by the power adapter. The amps can vary widely. On this 10 hub port, the output is 5V at .5A. I have other hubs that cover a range, with some having 4 ports at 3.6A.
So, if you may have the need to attach multiple devices at once, without much need for charging or powering the USB device, this 10 port hub may do the trick. If you travel, and are looking for something to connect and/or charge multiple devices at once, (bluetooth earpiece, Blackberry, iPhone, camera, etc....) USB hubs with low amps may mean only 1 device will charge at a time, while others may not even connect. This can be very frustrating.
It is also important to note the iPads will not charge with a random USB hub, nor will they charge connect directly to a computer. A special power adapter is required to charge the iPad. This is an iPad issue, not a USB hub issue.
It would be helpful if other reviewers would comment on the amps provided by the powered USB hubs they review, and if others could verify this observation.
Any other input by someone who knows/understands the power circuitry would be appreciated, as these are observations only by using various hubs in a trial and error fashion. For example, can one take a power adapter with an output of 5V 3.6 A and safely use this with another hub whose original power adapter has a lower amp rating?
