I spend most of my time in the path of hurricanes, we lose power 5-10x per year for between 1 to 8 hrs on average.

When we lose power the battery backup for the modem takes over(15hrs runtime), and we have other portable batteries to recharge our phones multiple times.

If things get really bad, we can pull out the camping solar panels and keep the phones charged. At that point, I expect the fiber will be down anyways and cell service is probably all that would be available.

Works quite well. I can usually still complete my work day on my laptop without issue.
