In short I find myself with a hub with independent power supply but this no longer relevant because only the charging port is used in its full capacity of 2A.
I have said that over time the contacts of the other ports are used poorly while their use was much less what little cause connection reliability worries about external dd (the USB key are less stringent).
Quality starting average finish did not help his aging.
Rather than waste time with the manufacturer, I'm still not know about the name, I prefer to bet on another product found on Amazon and 30% cheaper! Further customer support seems more present with this product :)
I would stick so just this fact: at this price point (> 30th) I prefer strongly advise against its purchase.
