Anker Uspeed USB 3.0 9-Port Hub + 5V 2.1A Charging Port With 12V 5A Power Adapter
I got the Anker Uspeed USB 3.0 9-Port Hub from Amazon for US$59.99, excluding shipping. Despite the long name, it's basically a 9-port USB 3.0 powered hub with an extra USB charging port. You can charge from all nine ports.
