Since my iPad is dwindling, I switched to powering it with a USB battery that is usually used for my Smobot (a controller for my Big Green Egg smoker). Working well!
I have turned off the alerts on all of the UPS that have that option. There are three smaller ones (wife's PC, my office PC, and the living room TV with cable box) that don't have an option to turn it off. Bummer. Like I really do not need the UPS to beep to tell me the power is out!
