The Satechi worked well enough to connect from the PC to other devices - and it packs a lot in a small space. But as others have mentioned, it does get very hot. Worryingly hot.
And maybe I was expecting too much from such a small package but when I tried to use it to charge my laptop, it would only charge very slowly - I got warnings from the laptop. So I was compelled to use the 2nd of those few ports for a separate charger.
Great for portability though, as long as your battery is well-charged.
