So it plugs into the wall, and requires a 9v battery as well for normal function? or is the 9v only there in case the power goes out?

9v battery is used as backup. The product description mentions this; however, the technical details say battery operated.... That's misleading

I installed a new one 11 November 2012 and haven't needed to change the battery yet. The previous similar one was good for approximately 9 years, I can't remember the exact date I initially installed the first device. The receiver plugs into the AC outlet and doesn't require a battery. You can purchase an additonal battery for the wall switch from Amazon as well...High Voltage 12v A23 23AE. There will be a battery supplied with your new purchase.

You can keep it plugged in to the wall. Not sure if batteries can be replaced.

The unit plugs into the wall and if the power goes out it has a battery backup. The iPod gets charged by being mounted on the unit.

Yes, it does need plugging into the wall. We are using one in Turkey where the voltage is just short of the English 240 volts and we have had no problem with it. I have not been able to find a battery type.

It allows you to use a 9v device by plugging it into the wall, there fore no need for batteries. It is not a charger

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

Inside the garage is corded but the outside device is cordless. It uses a 9v battery that is easy to replace. The device is attached to the outside wall with only two small screws.

Hello, I have a few of these. It runs on electric plugged into the wall. But I had an electrician wire a plug on mine so it can also use a 12 A 7 V battery too. It works great on both. Hope this helps.

Mine just came with battery. But looking on the back there is a place for a DC:9V adapter. So I guess you could plug it in if you had that type of power adapter.

It uses a standard 110 wall plug. I think it's way too powerful to run on batteries, and there isn't a provision for batteries.

The power source is battery.I think it is 9volts not sure but it is battery operated.

No, it is a stand alone device. You can plug it in to the wall to save battery power.
