Count Down Timer

I'm trying to locate a 110 volt 24 hour count down time for my rechargeable transponders, helmet & shoe dryers, etc.



Lots of 15, 30, 60 minute count downs. Even a 12 hour would work well.



These are not on - off timers. I'd like to set up my miscl. electrical equipment to turn off when I'm not going to be around to baby sit.



TIA
