Is a coupler the same as an AC adapter? Is the caller ID battery operated?

It has an AC adapter. I don't remember if it has a battery or not, I think it might take AAs.

the caller id is not battery operated, it requires the ac adapter. the only other connections are to the wall jack and to the phone.

To Dorothy; No, a coupler and AC adaptor are not the same thing. Please see web site http://deepsurplus.com/Network-Structured-Wiring/Telephone-Adapters-Couplers_2. Also, I'm glad you asked about the batteries. I had never looked before, and the answer is YES! It will take three AAA batteries.

You only need to use your telephone plug in. From the phone - to the caller ID - and then to the wall. Very easy. There is a battery back-up.

Yup just like the old days. No power needed. After I got this one I found an authentic vintage one on Ebay. Had to take it apart and clean the contacts but you can't beat the old ones. This one works fine but it just feels cheap and the ringer doesn't sound like the old ones. Your call.

Yes. It replaces the 4 pin adapter. The connectors plug in the same sockets. It works great - just get it all routed up to the battery before you zip tie it in as you may have to find the best route.

No A.C. adapter, batteries only. Mine is in use 10 months now. There is a low battery light. The back of the unit has a recessed cable channel like the idea of an adapter existed at one time.

You could use a battery pack from Anker. All that's needed is the right connecting cable to plug into the coupler. I believe the correct power cable connector is 5.5mm OD x 2.1mm ID. (http://www.amazon.com/UpBright%C2%AE-Worldwide-Double-Connect-Adapter/dp/B00E5JB5XI/ref=cm_wl_huc_item) Can anyone confirm?

Either one. It's the same as any other adapter except for the fact that it uses a proprietary connector.

We purchased this AC adapter: LEDwholesalers AC Power Adapter with DC Output Jack, 12V 4A, 3228So no batteries... not sure if that's an option as this is the only thing we've done. Works great and plugs into the outlet which is connected to the light switch.

For power it comes with a plug-in transformer you can use if have a way to run the wire from AC to the doorbell, or it can run on two AA batteries. I have one on AC and one on AA, both work just fine. They are wireless from the doorbell to the base station.

No. This is an analog phone adapter. It connects your phone to your router, but does not replace it.

Yes, both receivers are plug in. But similar models do have a "one plug-in" and "one battery operated" options. So read the descriptions from the sellers well. This model is also available with two push-button units and one, two or three receivers.

The adapter is NOT included. I am running mine on 6 AA batteries. Also my unit is NOT the very attractive yellow color you see in the pictures! Deceptive!!!!! Mine is an unbelievably heinous flat orange color. It's grotesque.

yep it just plugs into the original one. It uses the same 9 volt battery and has a long cord. It works well and does the job, but batteries don't last as long. I hard wired my DC adapter to an AC plug-in and that worked well for me...."no batteries" yeah !

The plug is for the Big ac entrante but you can use an adapter for small entrance, regards

No adapter, battery operated as far as I can tell. The batteries lasted a long time!!

I don't know. I replaced my old rusted doorbell and intercom. This one was very similar looking to my old one. As I recall it was a very simple wire connection. I think the size is critical though.

No, this is a simple 3-prong to 3-prong device. The plug shape is the same on both sides. It looks similar to this one, the photo shows the back side. http://www.telstarpro.com/files/images/ELECTRICAL/ROUND1/AC-52web.jpg

No, it does not. If your network has "power over Ethernet", you don't need a separate AC adaptor, but most networks do not have that, so you will need the AC adaptor. You want the Cisco Linksys (PA100-NA) Power Adapter for IP Phones. I just bought two on Amazon for $8.77 with Amazon Prime.
