EcoFlow DELTA 2 Max: what works, what doesn't?
What works well
- 2,400 W continuous output: enough for a kettle, air fryer, circular saw
- 15 ports in total: more than most competitors
- 1,000 W solar (dual port): the fastest solar charging on the market
- Expandable to 6.1 kWh: with 2 extra batteries it becomes a mini home storage unit
- LiFePO4 cells: 3,000 cycles, safe, long-lasting

Points of criticism
- Premium price: €1,199, not a weekend camper investment
- Heavy (23 kg): two people to lift it
- Large format: 50 × 24 × 30 cm, needs space
- EPS, not a true UPS: 30 ms switchover time, not 0 ms
