Does this phone require AC power, or is it powered by the phone jack?

The phone is powered by the phone jack, though the caller ID display is powered by three AA batteries. You do NOT need to plug it into household AC current, either directly or via a transformer.

It requires a 9 volt battery but does not need a power adapter as it just plugs in to the side of the phone.

It is like a regular cordless phone and nothing else... You can connect it directly to the land line... The base unit will need power outlet.

Both the phone base and portable handset requires a connection to an electrical outlet, so the answer to your question is "no".

Does not appear to need any additional power supply ( there is only one "jack" to connect to the "standard" phone line type connector)

Yes. These phones are typically powered by a PoE switch, so no power supply is necessary. If you don't have a PoE switch to supply power over the ethernet cable, you will need to purchase a power supply to power the phone.

I have this phone and without AC power it does work for only dialing and receiving calls on line 1; everything else is disabled.

No, like most phones with no cordless handset, it's powered by the phone line.

No. The base requires electricity. If power is out, these phones will not work.

It comes with a 110v transformer only. However, similar panasonic phones are available in shops which sell phone for overseas uses.

Yes. Both the base and handset have an AC wall adapter. However, only the handset has a battery (included, rechargeable).

Yes just the answering machine/main base has to be hooked up to the phone line. All 3 base units each have an AC plug that has to be plugged into an outlet.

No, it has 2 RJ45 telephone jacks and needs to be in line between a wall phone jack and the telephone base ( or a corded phone). It's also battery powered.

Not 100% sure. It does have a jack for an AC adapter, although doesn't come with one. I am not using one and am running it to connect my TV to a satellite receiver and a ChromeCast. It works great for me without external power.

This unit does not come with the power supply or power cord. Our units will ship with the phone, handset, and handset cords only.

It can be operated with only phone line power, but batteries are needed for anything other than ordinary telephone operation, e.g., speakerphone, memory calling. It does not have an external power supply.
