My folks have a medical alarm that runs over the internet - all good. But when there is a power cut, they lose their internet, and it triggers the alarm at the monitoring center, therefore ends up with family getting "the call".

So I'm looking at getting my folks a basic UPS that the ONT, router, alarm and phone can sit on for at least 10mins so my folks can call us to say theres a powercut and not panic.

Due to the low power drag with these devices (in theory), I take it one of these would be suitable - https://www.pbtech.co.nz/product/UPSPWR2555987/Eaton-5E-Tower-UPS--650VA--360W--2-ANZ-Outlets--Li

Or this there something else I could look at ?
