Surge damage is cumulative and affects everything that runs on electricity. Multi-outlet strips which promise surge protection actually burn out a little more with every spike in current. If they rattle when shaken, they re no longer protecting anything. Solve the problem one time at the switch box, protecting everything from your computer to your fish tank. It's very affordable, and surges are more damaging than most people realize.
Power outages are basically unannounced and can mean losing unsaved work on a computer.
A basic UPS provides enough battery-stored power to permit finishing a computer task and closing down. Your phone may not work. You will have to be careful with your refrigerator and freezer. You will lose TV news and entertainment. We can install a propane-powered Coleman PowerStation to provide from 8500 to 15000 watts.
