The USB 3.0 4-Port Mini Hub allows for up to four USB 3.0 devices to be connected simultaneously at a transmission speed of 5Gbps, while still providing connectivity and support for the older USB 2.0 (480Mb/s) and 1.1 (12Mb/s) devices. It works with high-bandwidth Super Speed USB 3.0 devices, such as webcams, flash drives, video surveillance cameras, digital video cameras, multi-channel audio and more. In addition, it supports fast charging for smart phone, tablets, and iPad.
I bought this to power an SSD I bought for my Wii U. Not only can it power it no problem, but it acts to recharge multiple controllers no problem either. It's sturdy design is solid and unless you try, it won't break on you.
