power source says "corded electric". But includes batteries. Which is it? I've only ever seen wireless ones.

It runs on batteries, but it also can be directly wired without using batteries, if there is a hot wire in the location that you want to put it up.

This is a wireless unit. Power is supplied by a 9v battery. The only "corded electric" power source is the receiver on the garage door opener itself.

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.

The power source is a little circular 3V internal battery. It is included with the device. There is also a light receiver on the face of the device that I assume contributes to managing battery power.

I haven't used the corded version. But the 20V is excellent!! So far love it..

There appear to be two discrepancies. The cable length disclosure and then the listing says it only comes with one battery. The wireless has two batteries...one for the computer, one for the sensor. Now that I look at the picture, the top is the wired computer and the bottom is the wireless. There are too many inconsistencies. If you're looking for the 548C I suggest you go over to eBay, where I got mine, and you'll find it for around $7.50.

It's just battery, but you can order a power cord, I believe. The battery is a 9v.

Mine came with an Ac cord. The description says it is battery powered, mine does not have a battery, just a cord. Sorry I can not help

Wireless uses batteries and no cables to attach and wire to string. Its all personal preference.

We hard wired ours. I'm not sure what corded means, but ours is not plugged in, and I don't think it was made to be directly plugged in.

I was just looking at a Worx model blower/vac/mulcher that also incorrectly said it needed batteries (for a corded model). I think it's actually an Amazon problem, as opposed to the manufacturer's.

It's corded. Have had these for almost a year and have been extremely happy.

It's not wireless. There's one thin line going from the sensor pad to the monitor, but it can be easily hidden. The pad itself works on batteries, so there's not a power cord.

Cordless. But mine doesn't hold the charge very well and it doesn't work when the cord is used. Make sure you can return it if it happens to you.

There is a small "backup" watcg type battery but it is not a rechargable one. Although I am happy with this unit, I do not recommend it if you are wanting to use it without a power cord.

It comes with a power supply for the wall outlet and yes it requires batteries only if you want to use it wirelessly.

Not wireless, you can plug into PC or MP3 player etc. The PC will charge battery or you can use usb adapter for 110 volt or 12 volt to charge battery if you have them, same way you charge your MP3 player. I have charged and used mine both ways, but it must be plugged into what ever to work.

Corded. I do not recommend this item though. After about 1 year the on/off button stopped working .

Strictly battery powered. Uses 3 AAA batteries wired in series. It also comes with 3 batteries that I have yet to replace.
