Shouldn't these have come with a power supply??

It should but it does not. You need a power supply for every repeater you run. Meaning you need an outlet close by to plug in your power supply into to feed your repeater. Try connecting the entire strand/length you need to test if you have any drop in voltage by the end of your strand. I've run 30+ feet with no issues and did not use the repeater I purchased. ( mainly because it did not come with its own power supply)

These simply repeat whatever signal is put into it, with a power boost. This is useful for having only 1 controller, but using these you can send that signal with plenty of power to however many strips and repeaters you want. For my build, I used a 360w power supply and 5 of these repeaters to power and send signals to about 10 RGB LED strips (2 strips per repeater) with just 1 controller. What I used: http://www.amazon.com/SUPERNIGHT-Switch-Power-Supply-Switching/dp/B008HARHN8 Edit: On the output side of the repeater, you can see two 'power' terminals. I wired two repeaters from each terminal from the above mentioned power supply. Alternatively, you can also use http://www.amazon.com/gp/product/B00B7BGAXW (though I've had mixed results with plug compatibility). For me, I have my repeaters wired directly into this cable: http://www.amazon.com/gp/product/B008LR6EAY, which then goes to a connector that attaches to the lights. Overall I would suggest using a DC power supply if you plan on using more than 1 of these.

Not at that price. This is perfect for my use and my lights came with a power supply so I didn't need to get another one.

Depends on your use I would say. In my case an AC to DC power supply would have not been used since I am using a DC source to power the LED controller and repeater.

Unfortunately not. Those are powered from the computer itself, these have an external ac port and a speaker plug (3.5mm or whatever the standard is now)

You need to power them with a receiver. You would run your computer into that.

No mic cables included, so you'd need to buy those separately or use what you have. Does come with a power supply, of course. :)

did you plug them in to your computer and make sure the power switch is on? if so send them back cause mine is great!

No. They only provide power. The other ports do provide power as well though.

I use these along with a power adapter, http://www.amazon.com/gp/product/B00HV3AUEK/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

The unit I purchased came with a power supply and there was no option to purchase without one. The supply itself is a small, simple 5.9v 1a supply; not worth much of a discount if it is not included anyway.

Mine did indeed come with a power supply. It was one of the standard two-prong brick-plug types that sometimes obscures other outlets on a power strip if the outlets are too close together. Wasn't a problem for us, though.

Yes. Each come with DC power supply. I believe they may also be powered via PoE.

Require a power supply: No; Batteries: My book says "to provide back up power". Others have mentioned that the batteries don't last to long

The power supply is indeed included, please check us out before you make your decision!

You need to plug them into the wall outlet to power the built in sub-woofers. As others have said, if you don't you are not fully utilizing the full functionality.

These are not powered speakers they require an amplifier or PA. Only then could you do connect it.

They are just speakers. They don't currently have anything powering them. So the short answer is no. Maybe they could if you added a reciever and hooked your computer to that, but you'd be better off (and will save money) if you go with a powered set made for a computer.

Nope, you will need a 120ac/12vdc power supply for these lights. These are light emitting DIODES, so you must observe the proper polarity when you are hooking them up.

Correct. You have to purchase cables separately. Does include power supply though.
