Is the "4-Charging Port (5V 1A &amp; 5V 2.1A)" model just a power supply for charging, or is it also a USB hub?

Greeting from LOFTEK, Thanks for your question. This item is just a usb port charger, not a USB hub. So it doesn't support any data transfers. Thank you.

USB ports can only supply limited DC power. Sometimes a two or three port passive (no power supply) USB hub can be useful, but don't expect a seven port hub to operate without a separate power supply. If you're inventive, you can construct a battery power supply with parts from Radio Shack so that you can occasionally operate away from utility power.

It has multiple USB port along with one mini USB port. Multiple USB port can be charged/powered at the same time.

This is 5V charger for USB devices. You can't use this to charge the laptop

It is not listed on the device. wikipedia says "Powered USB is a proprietary extension that adds four additional pins supplying up to 6 A at either 5 V, 12 V, or 24 V." I have a 5V 2 Amp adapter whose connector is too small.Output of the cable reads 5 V. I had to check because I had not heard of 12 V or 24 V in conjunction to USB.

Mine came with a "wall-wart" type USB power supply right in the box. Any 5v DC power supply that puts out 1.8 to 2.0 amps should work fine

The USB next to the charging port is 3.0. This is also powered when the laptop us powered off.

Its just the dock. There are 2 adapters - one for the laptop itself and a higher wattage one if you are using the dock.

Hello Tim. The USB ports can be used for charging one 2.1Amps device or two 1Amp devices.

No, it doesn't need a separate power supply, it can draw the power from USB port on a laptop. If you intent to connect it to an USB hub, make sure that the USB hub can provide sufficient power. Non/low powered USB hub will not work.

The hub has one high output power port on the side, that uses the AC adapter. The other 3 ports seem to run power through the main line without the AC adapter. How much power are you going to need to run you Hard drive, I don't know. I do know that my iPad only will charge with the power plugged in and it hooked into the high output port.

I am not sure I understand the question you have two standard USB out charging ports and one mini USB in port for charging the Anker

See Dan's answer, and the power connector is a small cable that plugs into the board on the device, that adapts it to the 4-pin connector to your power supply.

This is a charging BASE. It comes with a short usb cord but you need to supply the power.

Yes, underneath the grey rectangle on the black box with the wires coming out of it is a USB port. I used it to charge my Galaxy s3 etc. It is slow however. I think next time I may use it to charge a battery pack and then use the battery pack to recharge my gear.

Only for the USB hub, you have to get an extra charger if you want to leave it all hooked up.

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