Ours have a battery backup to keep the time in memory so the time will be correct when the power comes back on, but to be honest I have no idea if the alarm would go off with the power off..
And second, I have never seen a plug in alarm clock that doesn't take a 9 volt battery as backup to losing power. My clock works just fine with no power, you just don't see the display. It still tracks time and the alarm still goes off at the set point.
I never knew either until I woke up to the alarm and was surprised to see no display. Thought it was broken until I fully woke up and realized the power was out.Ours have a battery backup to keep the time in memory so the time will be correct when the power comes back on, but to be honest I have no idea if the alarm would go off with the power off.
I've been meaning to change the one in my clock radio. Just did. I always write the date a battery is installed (a practice we used for equipment at work). The battery I took out was installed in 1996 !I never knew either until I woke up to the alarm and was surprised to see no display.

I use my phone, but with a pleasant melodic sound, not the default.
It's so nice to wake up to "Spring" music instead of a strident beeping.
