✓ What We Liked
- 1kWh of usable capacity for camping, remote work, and short outages at just $599
- 1,800W continuous (3,600W surge) covers microwaves, coffee makers, and most kitchen loads
- Entry price undercuts the EcoFlow DELTA 3 Plus while keeping DELTA 3 platform features
- Cheaper than the Anker SOLIX C1000 for shoppers prioritizing price over expansion
- Right-sized for first-time buyers who don't need a 2kWh+ unit
✗ What We Didn't
- 1kWh runs down quickly on high-draw appliances
- Lacks the expandable headroom of the DELTA 3 Plus for future growth
- Fewer premium extras than pricier DELTA 3 models
- Recent release — limited independent long-term testing at launch
