does it come with an A/C adaptor?

Yep. It's a standard 9v adapter similar to the ones that power guitar pedals, etc.

This one does NOT. There is one just like it and in the pictures you will see the AC plug. The other unit you can find on Amazon and it runs about $25 but it is worth it. If you get this particular item, you are going to be disappointed.

Sorry don't know the answer to your question... I am only using it for our A/C.

Not for me. Mine works for as long as I use it without the a/c. It is a great machine.

I would find out, I also got one, but it came with a A/C adapter. How are you suppose to play it. I have had two of them. I love the system. I would call the company you got it from.

Sort of ... Mine came with a cable that has a USB connector on one end, and a round connector typically found at the end of A/C adapters on the other end (and which connects to the unit). Without additional adapters, it will NOT plug directly into a standard wall outlet.

It doesnt come with one but you could buy one at radio shack or such since its just an ac adapter.

No, it does not come with an AC adapter. It is powered by the USB connection. I have had no problems with just using the USB connection as a power source.

It does Jeff. You'll need an A/C cord - they're $20Enjoy this awesome little mount!

I does NOT come with the AC adaptor. You can use the one that came with your laptop or buy another.

Not sure what you mean by an "AC Adaptor". It comes with a standard power cord.

It has an AC adaptor. This bike is awesome and you won't be sorry you bought it.

No, it doesn't come with an AC adapter. It only includes the USB charging cable that connects to your laptop, desktop, battery pack, wall or car charger.

I don't own the unit yet however yes this does require an AC adapter. It looks to be on the front of the unit in the bottom left corner (look at the 3rd picture you can see it).

Yes - these don't come with an A/C adapter, but you can find them separately on Amazon. The phones are also capable of running on PoE (power over ethernet) if you have a network with that capability, making the adapter unecessary. http://en.wikipedia.org/wiki/Power_over_Ethernet

No. You have to buy AC adapter separately. I concur with the others who have answered this.
