What is the DC port for? Does this part require an external power supply to run?

The DC charger that is included in the package is NOT needed to run this unit. It is there for additional power for some of the more power demanding units such as certain external hard drives. Laptop USB ports usually only offer 500mAH of power.

No there is not a power supply with it but I consider that a good thing. Keeps the price lower and allows me to buy on that fits my needs. Like a 500 watt wouldn't be nearly enough for my build but might be for yours. If it came with a stock PS it'd probably just end up another unused spare in the back of the closet.

I purchased the 7 port unit which has a power supply. I am more cofident in say the 7 port unit will work. I doubt the non power unit will work. I hope that helps you.

no it does not have a external power supply in the box. Although it does have an input jack for a 5 vdc power supply to be added. These are very common and easy to pick up at any electronics store

Mine DID NOT come with a power supply but there is a port for a 5 volt power supply

Obviously the unit needs to be powered for it to be function. The top left "input" on the unit is for 12v in. The wall power adapter that comes with the unit needs to be plugged in, coax from that right into that port is how you accomplish that. I hope that answers your question.

it does not. The computer and the docking station will each need its own power supply.

does not come with a dc power supply. however all it is is a mini (not micro) usb connection. does not come with antenna, that antenna looking thing is just a window mount for a magnetic antenna.

no, for that you need a power/voltage converter. this is just a plug adapter.

You have to use an external 12v dc supply, not sure about the double pole ?

in fact, I'm using it JUST FINE with a 5v power supply. since it works great with 5v, I see no need to over-voltage it with 12v. yes, it will have an onboard dc/dc converter but as I found out, 5v is enough for it. center pin is plus, of course.

No the model I purchased did not require external power. I needed to convert HDMI from a new laptop to VGA to supply video to an older but still very functional larger fixed monitor. It worked fine. If you have a similar need be sure to check the monitor, some have a dual input VGA and PCI which gives you a choice in the converter/cable that you choose.

It's a good standard power supply that will power pretty much anything that runs on 12 vdc. It's always a good rule to use a power supply that's rated at least double the current load connected to it. In your case you would have plenty of reserve power to run some other things at the same time.

No it has three built in outputs (the button to switch one input to the other and then the two USB outs to the computers) on the front there is a DC input, but mine is not pulled into a power source and has been working fine for the last year.

It has to get it from the USB because there is no other power supply directly going into it, why is this question even being asked?

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.

No direct connection to power supply necessary or possible. Whether your existing power supply will be adequate is more a question of how many hard drives and other components are powered by it.
