Does it REQUIRE the use of the AC adapter

It does not require the use of the AC adapter, it will work without the AC adapter being plugged in. It will only work, however, as good as any non-powered USB hub, meaning, there would be a limit to the amount of power that can be used by the devices connected, some devices will require the additional power, that is the advantage of the additional AC Power source.

Yes, it comes with an ac adapter with long cord. Mine is still running well, BTW.

No there is no ac adapter. It does not require power. The switches on the front are mechanical, not electrical.

Yes, mine came with a DC adapter (transformer) that plugs into an AC outlet.

The AC adapter needs to be plugged in to work. It works great and fast when plugged in!! Happy Day!!

Yes, the AC adapter is the only power connection as this digital photo frame does not run on batteries, which I see as a negative.

Yes, it has two options. One, it comes with a AC adapter plug. The second option is using batteries without the adapter.

You shouldn't need an AC adapter, it has a cord that draws power from the USB port included. If you want to power it with a separate power source, you would need to use one that has a USB plug on it. USB is a standard 5 volt DC, although the milliamps will vary.

You can use it both with batteries or pluged into a 9v power source. But there's no AC adapter included !!!

It comes with an AC adapter. I use mine with the AC adapter most of the time, seems like the signal comes in stronger that way.

You do not need to purchase the AC adapter. The Arduino can be powered by the USB cable attached to the computer or any laptop AC adapter that has a USB connection, OR by a 9V battery and the connector appropriately attached to the breadboard.

Yes, works with AC adaptor only. I don't even put batteries in unless I'm going to be using it where AC isn't available.

No but if you acquire the AC adapter that it is designed to use you never have to worry about using its batteries

Yes. It doesn't need a power adapter but it will need to be plugged into a power source via the cable that comes with it.

Count me as wondering as well--I'm not going to buy it if it doesn't come with AC adaptor. The picture that someone posted shows it with one, or at least that's what it looks like to me.

You have to plug it into a wall socket with the AC adapter that comes with it.
