Question [Q] Other reasons to buy except for the special design of usb hub?

I have to admit that I am to some extent accustomed to post here and chatter over trifles when I am free and spend a lot time with my gadgets. But there always comes some boring things, such as the low power of ipads and phones. And sometimes I found the usb connectors on my PC is not enough to support my work as convenient as possible. So I searched on Amazon and found a relatively suitable item maybe I can use to solve my issue .

http://www.amazon.com/Unitek-Chargin...eywords=unitek

Does this item worth being considered as a perfect one? Have the charging ports of this hub has the same capability of power supply as car charger or wall charger ? What will be the prominent performance? It seems that this seller has various kinds of similar products named 'USB HUB". I am afraid I could not make any decision but be attracted by its appearance and price unless you guys give me wise advice. Thanks a lot!
