Does it matter which port you plug things in to? Which port is the 1AM and which is the 2.1A?

Yes it does matter but neither port charges an iPad as advertised.. This is a replacement unit since my first one was defective. It's lasted 4 months and is already very finicky when it decides it's going to work or not. I would not purchase this again.

one on left is 1 amp is for iphone, one on right is for ipad - and yes it can make a difference - ipad won't charge on 1 amp and the 2.1 is too much for some iphones - I take a white magic marker and put a dot on to identifiy the 1 amp

USB 2.0 port will remain a USB 2.0 port because of the bus speed. It won't make it 3.0 even if you plug in this hub. Hope this helps.

The difference between ports is the amps that the specific port pushes to device

You need to use a power adapter. Several of the ports no longer function (side note).

No, the most you get from each individual port is 2.4 amps. Or the 4.2 amps using both at the same time.

No it will not. Power is less than 1A for both ports. I ended up returning for a refund.

1A port can charge a smartphone; another port (2.1A), is for larger devices, such as the Apple iPad and other tablets. Currently there are smartphones that accept the 2.1A input as well.

No, the 'combined' output of 3 ports is 4.4A. The 3 ports are 1A, 1.3A and 2.1A, all at 5V.

USB 1.x and 2.0 have the same power pins 1 and 4 with +5v and ground, respectively. Will work on both.

The Discription says "Plug in to Any USB 2.0/1.1 Interface". Hmmm! Is this just for Power?

All multiport USB chargers will split the power between the ports but this one is 3A. One port will get 2A and the second 1A so it is sufficient to power all new devices that require 2A charge (like iPad and large screen smart phones) and use 1A port to power second device without compromising on time. Just make sure to use original device cable.

well as far as i can tell its 1.2 watts x 2 would be 2.4 watts total so 1.2 per port.

It only uses 1 port, but I opted to use a Logitech performance mouse and keyboard. For me, I desired a larger mouse and smaller keyboard. They work great!

the way i see it if you only use one port at a time you get full power. 1/2-power when both in use.

Probably. 2 outlets are 1amp and 2 are 2 amps. Order it and try it. If works keep it if not then return.

I have a 2.0 hub attached to one port on this unit and it works fine. Not a problem.

Yes . You have 1.0 e 2.1 . Two ports, one of each. mine worked only 5 months. was great while work.
