I use a UPS which also adds surge protection in addition to the battery. One of the best investments I have ever made, especially since I live in a big apartment and from time to time there’s some neighbor doing idiotic things to the wiring on the building.

Definitely look into a UPS if you are worried. It can help with shoddy power or blackouts. Some also have surge protectors built in. A 1500VA one should be 1,000w equivalent. The batteries are lead acid, and generally only last a few years.
