does it require a power source?

Yes, either batteries or the AC adapter that it comes with, but well worth the money for my 86 yr old father to hear the phone ringing while he watches tv,

Although the user manual does not say that it needs a power source, it came with a USB cable. I was not sure why, later I noticed that the device has a mini USB port on the side. I had it connect to my Cable box that has a USB port. The device did not work properly (it kept flickering) without using USB cable. It works perfectly now.

No external power source required. I added the required AA batteries in order to keep the call memory intact. However, if you want this as a wall phone, you are wasting your money. The receiver does not stay in the cradle.............

This item does not require a power source nor does it come with a plug. Thank you for your interest in this item and for your question.

It requires auxilliary power. USB won't power it. But it comes with a power pack.

No. It does not need a power supply. It simply collects the VHF from one antenna and the UHF from another and combines them into one cable.

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

No it does not require battery power. It is basically like a pair of earbuds attached to your iPad or Mp3.

Yeah! So I've plugged mine in for a power source, but it takes batteries.However, it doesn't have a speaker/amp so you'd need to orchestrate a way to do that

No, it will need to get power from USB cable. Meanwhile, it will also need to get signal and drawing through computer's support.

No, I draws its power from the mother board. You may be thinking of USB hubs, which often require external power. Hope this helps.

It does. However I returned it soon after getting it. It was simply not enough power.

Yes, it does require AC power. It comes with a power adapter to plug into the wall. Very simple unit and does exactly what it sets out to do. I recommend.
