Oh I'm certain. The unit actually appears to be more aimed at in-wall installation, but it also came with a plastic stand and an AC adapter.
Don't suppose you remember what unit it is?
I would upgrade it, but there's nothing else quite like this model on the market that I can see, and this one isn't even sold anymore.
What exactly do you need it to do?
It has an AC adapter, but also uses a phone chord to talk to another X10 adapter.
Ah. It uses an external interface. Most of them are integrated now which is why using it on a UPS wouldn't work.
While we're on the subject, why is it that nearly all these battery backups tout the fact that they have an alarm when on battery power? I hate those damn alarms. I have four battery backups at home, and when the power goes out it's a cacophony of beeping.
In case you've not noticed that its your lights are off or your TV/whatever is off...
