Amazing power backup
This unit is incredible for home backup. We had a blackout last week, and it powered our refrigerator, some lights, and the internet router for nearly a day. The LFP battery technology is a huge plus for longevity.

Solid for emergency use
We got the DELTA 3 Ultra for hurricane season. It charges up quickly from the wall, and the 3072Wh capacity is ample for our basic needs for a few days. It's a bit larger than I expected, but its performance makes up for it.
