External USB 3.0 Hub behave normally or ideally with 2.0 on Win7 ?
I am currently using a Toshiba Satellite L535 laptop that comes with built in USB 2.0 ports. It runs Window 7 OS. From my understanding, a USB 2.0 port can provide a maximum of 2.5W Power Output (5V x 500mA) and a USB 3.0 port can provide a maximum of 4.5W Power Output (5V x 900mA). Please tell me if I have a wrong cognition.
I am thinking of purchasing an external USB 3.0 hub and connect to my existing USB 2.0 port on my laptop. But after connecting the hub to my current USB 2.0 port, I wonder if the ports on the hub perform ideally as an USB 3.0 port by providing a maximum of 4.5W Power Output. I chose a used brand as a keyword to search online. I conclude two choice as the followings:
Amazon.com : [10 usb3.0 Ports ] Unitek USB 3.0 Hub 10 Ports with 12v 4a Power Adapter a to B Cable Compatible with Windows Vista / Win7 (32/64-bit) and Mac Os 9.x or Latest Version : Usb Network Adapters : Computers & Accessories
Amazon.com : Unitek 8 Port USB 3.0 Hub (6 Usb3.0 Ports + TWO 5v 2a Ipad Charging Port) with 12v 4a Power Adapter and Usb 3.0 Cable, Via Vl812 Chipset, Support Windows Xp / Vista / 7 / 8, Mac Os X 10.8.4, Linux : Network Hubs : Computers & Accessories
If I prefer the gadget with more ports( like the first ),i wonder if there is any limit for the number of the devices? Or the less the better? If I prefer a one ( like the second )to charge my Apple gadgets at the same time, could it be possible and smooth ?
Please advise as you wish.
