Not actual measurements but the markings, iirc, say 2 ports can provide 2A while the other 8 has max 1A. I'll update when I get home later.
By the way, I've noticed that it doesn't charge at all when charging a battery that's been drained to the point where the phone or tablet turned off by itself.
I also noticed that, other than my Samsung, other gadgets (iphone 5 with original cable included) experience messed up touch while charging.
Other than the above glitches, it works fine. We've been using it daily since December last year with 2 to 4 gadgets at a time and sometimes overnight.
