Do I need to terminate ( 50 ohms or else ) the unused ports?

No, Just make sure your Master unit is attached to the output labeled DC Power Pass and Slave units off other ports to insure 2 way communications between units

I just capped unused ports to protect from weather. Otherwise functions fine with open ports.

Yessir, i recommend doing that over the connectors. They connectors can be a bit sketchy.

I only use the uhb ports but there is many different ports on the back, you should check with dell.

Not really. I only bought it because I needed more ports. Unless you need more ports or the controller on the motherboard isn't working. There is no reason for it.

I am not sure, but every one of the ports work. Although I can't give you a direct answer since mine almost caught fire after 3 months. But all of the ports worked in the time that it worked.

I am using 12 of the 16 ports and it does not get hot. In fact it is barely warm at all

The power supply that comes with it is rated at 2.5 amps, so I would say that if the total draw is less then 2.5 amps then you would be good. The max you are supposed to draw per port is 0.5 amps, so times 4 would be 2.0 amps. It'll probably work even if all four on at the same time.

Yes. The ports correspond to wattage output. Using the wrong port would cause a higher watt device to charge slowly or a lower watt device to overheat.

Get the voltage and polarity right and you should be ok. Just be careful not to fry it.

Kent, I'm not sure. I don't have a mini-displayport available to test my unused plugs, but there is a rectangular one you can see in the picture; second row, third from left. For size, you can compare it to one next to it, which is modem port plug. Best answer I can give. -Scott

Solder it to your main positive and negative nodes on your motherboard. make sure the amperage and wattage are useable.

Correct... I haven't tested to see which port(s) would be 'ramped down', but the effect would be that one or more devices would charge a bit more slowly. Chances are good they will all charge, and pretty fast (you're only "missing" 200mA), but it won't be all three devices at full speed.

Yes... I had that port burn out after 6 to 8 weeks. They sent me a replacement under Warranty.

The port should be OK, just notice the power. If your laptop has Nvida graphic card instead of integrated intel graphic card, you may want to find a higher power unit (90W).

They are not necessary, but I have found that the voltage feels stronger without them, even on the lowest setting. So, it can be done, but it might be too much "zappage".

Yes, if the ports are different sizes just get a converter which are dirt cheap on amazon. Enjoy!

I hooked it to system with 8 ohm impedance and works perfect!However, buy an oversized electrical wall box or an open audio box, otherwise unit fitting will give you headaches.
