Modeled runtime, reference loads

Full-Size Refrigerator · 150W

RIVER 3won’t start
Explorer 300won’t start

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

RIVER 35.2 hrs
Explorer 3006.2 hrs

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 RIVER 3 if you want the better all-rounder — it takes the WattScore 82 to 74 on our bench, and it's the stronger pick for desk backup and weekend car camping.

The Jackery Explorer 300 still makes sense if its strengths line up with your use case — it's positioned as budget entry point, light duty, 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.
