EcoFlow DELTA 3 Plus vs Anker SOLIX C1000
Same bench, same derating, same five axes. Our pick: EcoFlow DELTA 3 Plus (WattScore 91 vs 87) — but the right answer depends on which spec you're buying for. The table settles it.

Modeled runtime, reference loads
Full-Size Refrigerator · 150W
Modern 18–22 cu ft units average 100–200W while the compressor runs, cycling roughly a third of each hour. The 1,000W+ startup surge is what disqualifies small stations — capacity is rarely the first problem.
CPAP Machine (no humidifier) · 40W
A bare CPAP draws 30–60W. Turning on the heated humidifier roughly triples draw to ~90–150W — budget for it if you use one. Use the DC adapter where available; it skips inverter losses and buys ~20% more runtime.
The verdict
Buy the EcoFlow DELTA 3 Plus if you want the better all-rounder — it takes the WattScore 91 to 87 on our bench, and it's the stronger pick for fast-charging 1kWh class leader.
The Anker SOLIX C1000 still makes sense if its strengths line up with your use case — it's positioned as value 1kWh with 600W solar input, and per-row wins in the table above show exactly where it pulls ahead. Cross-check both against your actual loads with the runtime calculator before deciding.
