The Header with the USB is top, the current is flowing also from all three outlets, which I also find top !!! But actually there's 5 star. A star I have to deduct because the bar now and admits a slight buzzing or humming sound and because the Red shit lamp between the USB ports constantly burning and I still have no eco power but good old Fossielen get power but, I'm the lamp Disconnect. Then maybe it'll work with 4.5 stars, Gelle
