The Amazon power source shows "battery-powered" but it as AC power. Is the battery solely a back up or is that the primary source?

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.

Yes, the alarm is AC power. The battery is only meant for the possibility of a power outage. The battery only last for the 36 hours after the alarm is triggered, but I don't know how long the battery last if it is not sounding. Since there is only pull on the battery after the trigger, I am guessing that the length of the battery life is as long the battery itself. I have one more thing to tell you. This thing is pretty loud when it goes off if you haven't heard it yet, so you'd definately be able to hear it...probably in your neighbors basement!If you have anymore questions, don't hesitate.

AC powered with no battery backup. They have a five foot power cord included.

I suggest going to their website to get the answer to this question. You can probably find the manual online. I have no problem using it as a battery powered device.

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

From what I have experienced, there is not "battery" on this product. So it has to be plugged to a power source.

it does have a battery back up. but you must install batteries and use the ac adapter for power source.

9v battery is used as backup. The product description mentions this; however, the technical details say battery operated.... That's misleading

Not battery powered. Has a transformer that plugs into 120VAC. The transformer output is low voltage AC.

This radio only runs off AC power (120volt). I can not remember if it has battery back-up for the clock. OBTW this is a very nice sounding radio with the ability to work from a number of sources .

If the device has a cable with a USB tip, the AbsolutePower will provide power and charge from an A/C outlet. It's not a backup battery source, though.

Same question twice...It uses both battery and corded power...it's small, though. I sent mine back.

I got to ask, are you sure it's hooked up to the "Battery" side of the UPS and not the "Surge" part? I don't know what type of UPS you have, but I have had several friends find out the hard way that not all the outlets on the UPS are the same. Roughly only half of the outlets are connected to the UPS's battery while the other half are basically just a fancy surge protector/extension cord type outlets with NO battery back up even though they are a part of the UPS.

This is AC only and there is no battery inside. You could use a small UPS for computers like you can get at an office supply store and likely run it for a few hours. The specs say less than 50W so it is on par with a laptop.

If you wish to charge the included battery from an AC power source, you will need an optional power supply

Adapter, plug in, and battery back up but assume you would not use the batteries as main power unless you had to.

I know there is a battery backup, but I have mine plugged into an outlet. I don't know how long the battery is supposed to last, but I wouldn't recommend it as your primary source of power.
