Bluetti EB3A vs Anker SOLIX C300
Same bench, same derating, same five axes. Our pick: Bluetti EB3A (WattScore 81 vs 80) — 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 Bluetti EB3A if you want the better all-rounder — it takes the WattScore 81 to 80 on our bench, and it's the stronger pick for strongest inverter under $300.
The Anker SOLIX C300 still makes sense if its strengths line up with your use case — it's positioned as USB-C heavy travel kit, 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.
