Is the base unit powered by batteries, or an AC adapter?

An A/C adapter but it is very cheaply made and mine did not get power. I returned it.

The base unit plugs into the electrical outlet. It does not require batteries. The two hand-held microphones require batteries but they are included.

Base includes charging with AC. You can buy an additional ac adapter, but I see no reason. I bought an extra unit and could have bought the ac adapter, but I just rotate each unit as they need charged

The unit does not use batteries. It is powered by a AC/DC transformer. It is not powered by line voltage. We have used this unit with DSL in the house, but always isolated transformers by use of a power strip with filtration.

No ac adapter. Sucks because eats the batteries in no time. So rechargeable batteries is the way to go with this.

Yes, it is both battery and AC powered. Bought for my daughter last year for Christmas and she is still using it today.

Yes, the unit has a AC power adapter since it is not a USB-powered device. We'll have to verify the amperage of each USB port.

The adapter I have is AC powered and not battery operated. I don't understand the question: "without AC adapter..." and "rather than battery operated." If it is not powered by AC or a battery, how is it supposed to be powered. This unit plugs into an earphone receptacle on the computer. These ports don't supply power like a USB port does. I don't think my answer helps much.

It takes batteries, but there is an ac adapter as well as a car adaptor sold separately

Although the unit comes with an AC adapter it's for charging only and for some reason does not allow direct AC use. I found this out the hard way as the batteries do not carry a charge longer than a couple weeks and I tried plugging in and using. Only when the battery was charged could I use it.

It only works by being plugged into an outlet. It is not made for batteries.

No AC adapter. The batteries last about a month. My daughter uses it all the time for her daughter.

Mine actually has an AC adapter so we plug it in to use it. I heard the rechargeable ones didn't work too well.

It is just an AC adapter, but will hold batteries. Unfortunately I can't get the CD to spin long enough to hear it play, working on returning it!!

It's detachable from the base, base connects to the regular power plug. No batteries.

It does indeed include an AC adapter and alternatively will work on batteries. Nice scale.

No; find no battery well in the unit; uses step-down transformer for 120V to 9VDC 2.5A minimum
