✓ What We Liked
- 3,840Wh LiFePO4 with 4,200W output, expandable to 26,880Wh
- $1,299 list is aggressive for a near-4kWh expandable station
- 4,200W runs the heaviest household loads and power tools
- Far cheaper per Wh than the Anker SOLIX F3800 for emergency home backup
- Expandable path rivals the EcoFlow DELTA 3 Ultra at a lower entry price
✗ What We Didn't
- 3.8kWh, 4,200W hardware is heavy and effectively stationary
- Expansion batteries add cost on top of the $1,299 base
- Pecron's support and accessory network is smaller than mainstream brands
- Recent release — limited independent long-term testing at launch
