Anker SOLIX C1000 vs Bluetti AC180
Same bench, same derating, same five axes. Our pick: Anker SOLIX C1000 (WattScore 87 vs 84) — 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 Anker SOLIX C1000 if you want the better all-rounder — it takes the WattScore 87 to 84 on our bench, and it's the stronger pick for value 1kWh with 600W solar input.
The Bluetti AC180 still makes sense if its strengths line up with your use case — it's positioned as most Wh per dollar in 1kWh class, 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.
