Uninterrupted Power Supply

dealing with power issues

Do not buy (again): EATON Ellipse ECO.
Bought 2x and they keep having random issues hard to troubleshoot, resulting in loss of power mid-work (what it's supposed to prevent).
12 months in, and one of them seems to have reached the end of its battery life!
