The differences that matter
- 2.05 → 3.6 kWh: with a 1,000 W load, about an hour and a half more runtime on the DELTA Pro.
- 2,400 → 3,600 W continuous: above 2,400 W the C2000 is not enough.
- UPS 10 ms → EPS 30 ms: the Anker switches over without interruption; the EcoFlow with a brief pause.
- 2.3 → 2.875 kW maximum charge power: the EcoFlow recharges a little faster at full power.
Which one to choose
Choose Anker SOLIX C2000 Gen 2 if…
you carry the unit around often: 18.9 kg, USB-C up to 140 W, a declared idle draw of 9 W, a 5-year warranty and expansion up to 4 kWh. You accept less output to start heavy loads.
Choose EcoFlow DELTA Pro if…
you want capacity and output at home level: four mains outlets, 7,200 W of peak output, solar input up to 1,600 W and a declared operating range of -10 to 45 °C. The practical cost is 45 kg to move, even with wheels and a handle, and a shorter warranty.
