Yeah, it's possible, but I don't need it. I just need something to keep things going through blips in the power, which is the most common type of outage we experience in our home, fortunately. If I had to estimate, I'd say that 90% of our power outages are 1 second long or less, 8% are about 2-5 seconds, and the last 2% are the kind that last 10-24 hours, which we haven't seen in years.

The UPS I linked is rated for only about 3 minutes at half load. That's more than enough.

And when the power is out, we're usually fine with browsing on our phones until it's back.
