I have a number of them throughout the house and studio. The big benefit is that they give me time to shut down. None let me continue past around 15-20 minutes. All of them let me put some units on the protection circuits while leaving others (additional monitors, printer etc.) out.

When we went solar last year, I expected that the big batteries installed with the system would eliminate the need — then we had a 12 hour power outage in the middle of the Silicon Valley. The changeover to the big batteries had a noticeable time lag of about a second—much longer than my UPS units so they are still in the system.

Besides three UPS boxes for my studio, my wife's and the router/backup system, I have additional boxes with 1500W batteries for my chair and bed without which, I could not get out when the power goes down.

So called 'power conditioners' are useless for this task.
