Can the system operate with just batteries or does it also need AC?

It requires 8 C batteries. I have only used it on AC power. I love it so much that I have ordered a second unit to use in a different part of the house. Enjoy!

Solar is nothing more than a battery charger. If you can operate your a/c unit without plugging in or using a genertor then yes you can.

It has an AC adapter. You also have the option to use batteries for thr parent unit.

No. There is no built-in storage battery; so it must be connected to AC power.

It's battery operated, however, you can also use an AC adapter, but that's not included.

Nope. It's battery powered only. You have to modify its scheme if you want to power it up with an ac adapter.

No, it uses A/C and/or 4 AA batteries so you can take it with you on picnics or the beach or just move it room to room without having to use the A/C plug in.

No. Just ac. Why not just purchase converter? Then u have for other items as well.

no, only the AC adapter and of course you can use batteries; while every fan is going to make some sound, this is one of the quieter ones I've owned

Can use the A/C adapter instead of batteries. Have not tried to power it with just the USB, but it might work.

According to the product description above, batteries are optional: "For added convenience, the thermostat unit can be run using battery power or using power from your heating/cooling system, giving you the option of permanently eliminating battery changes."

AC power is the primary source and the battery is the backup. FYI I used it for two months with just the battery and it worked fine.

you can take the battery out and operate on the AC, it does come with the adapter. also it runs on the battery and the adapter charges the battery , and it will play while the battery is being charged..

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.

It is not a portable unit and does not use batteries. It must use the power chord to operate.
