Is the receive portable or does it have to stay connected to the power source?

The receiver is powered by a plug in brick that converts 110 volts it to 9v 500ma DC. There's no room in the receiver for a battery. You could probably hook it up to a 9v battery; not sure how long that would last.

Once in a while, I use mine where there is no 110 volt power. With two 9-volt rechargeable batteries in parallel (producing 9 volts) I get about 24 hours of use.

Yes. I leave it connected to my laptop most of the time so it stays charged. Enjoy. I think it works well for its size and very easy to sync too.

It must stay plugged in. If you have a Bluetooth radio, you may have some interference in the picture as mine did.

Receive while charging, but you can't transmit, you have to unplug charger to transmit. Battery will last a full boating day.

Yes, the transmitter needs power to transmit. It comes with a long cord with a very thin wire connecting the last 4 or 5 feet to the transmitter.

This Bluetooth receiver comes with its own AC power adapter (about 1"Hx1.5"Wx2.5"L) that plugs directly into the little block with a mini-USB connector. Output from the receive is via a 3.5mm stereo plug to L-R RCA plugs for attaching to any standard receiver, amplifier, or other controller device. I was so impressed with it that I purchased a second one to attach to a different system in another part of my house. You won't have to purchase anything more to get connected or for operation. Count on being impressed with this relatively simple, unobtrusive little device.

yes, the transmitter has an internal rechargeable battery, it does not need to be plugged in, in order to work

It is portable in the way that you can use it in many room or take it with you when traveling. It does have a cord so it is not a good solution if you lose power. I think this would be best in an RV or maybe in a hotel. Hope this helps!

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.............

Yes..it's pretty portable and lightweight. Just unplug it and move it to the other room. Granted, after awhile it might get annoying....but I'm sure it wouldn't be that bad.

This device is not contain a battery. So you will need a fixed power source.

Yes, I've connected many power sources w/ the extensions I have. They stay connected very well, to the extent that it's not at all easy to disconnect them.

There are 2 power sources. You can either plug in to USB or the wall for it to work.

No, although the directions in the box say to connect it, you do NOT need to. There is no difference when you plug It in or keep it out.

This unit needs to remain plugged into the audio output or headphones jack of your non-bluetooth equipment in order to pair and receive on whatever bluetooth speaker, headphones, etc. you wish to receive on. If you mean do you need to keep it plugged in for charging it, the answer is no. Once it's charged, it will operate until its charge is used up and then needs recharging.
