✓ What We Liked
- 3,000Wh built-in capacity, expandable for whole-home and off-grid backup
- 3,600W continuous output runs most 15A household circuits and heavy power tools
- Sub-50-minute full AC recharge is among the fastest in the 3kWh class
- $2,899 lands well under the Anker SOLIX F3800 Plus ($4,799) while covering the same expandable-backup use case
- Scales past a single unit for multi-day emergency home backup
✗ What We Didn't
- $2,899 is a premium outlay vs sub-$2,000 2kWh alternatives
- 3kWh plus expandable hardware is heavy — not a grab-and-go unit
- Add-on batteries push a true whole-home config well past $3,000
- Recent release — limited independent long-term testing at launch
