How long will the EcoFlow River 2 Pro run your appliances?

Last reviewed 2026-10-26

Quick answer

The EcoFlow River 2 Pro (768 Wh) runs a full-size fridge for about 10 h 53 min, a CPAP for about 18 h 39 min and a Wi-Fi router for about 2.3 days (54 h) on its AC outlets. Its 800 W output easily covers the brief surge of about 1,200 W when a fridge starts.

162 W running + startup surge

Startup surge of about 1,212 W is well above the 800 W rating. Many stations handle short surges, but check your manual's surge figure, and start big motor loads (fridge, pump, AC) one at a time.

Uses 85% of the rated 768 Wh to cover inverter and conversion losses. Real runtime varies with temperature, battery age and how often appliances cycle.

What the EcoFlow River 2 Pro can't run

These draw more than its 800 W continuous output, so the station will shut off: Microwave (1,000 W cooking power); Electric kettle; Coffee maker (drip); Toaster; Induction hot plate; Space heater (high, 1,500 W); Portable AC, 10,000 BTU; Sump pump, 1/2 HP; Well pump, 1/2 HP; Hair dryer; Vacuum cleaner; Circular saw (7¼").

These might trip it as they start, because their startup surge is far above its rating: Window AC, 8,000 BTU; Sump pump, 1/3 HP. Many stations tolerate short surges, so check the surge figure in the manual, and start one motor load at a time.

Charging the EcoFlow River 2 Pro with solar

The EcoFlow River 2 Pro accepts up to 220 W of solar. Panels usually deliver about 75% of their rating, so it takes around 300 W of panels to max that out. Then a full charge from empty needs about 3 h 29 min of peak sun, which a single sunny day can cover. Smaller panels take proportionally longer. Try other panel sizes in the solar recharge time calculator.

Frequently asked questions

How long will the EcoFlow River 2 Pro run a refrigerator?
About 10 h 53 min for a typical full-size fridge averaging 60 W, or 7.3–16.3 h depending on the model, room temperature and how often the door opens. Its 800 W output easily covers the brief surge of about 1,200 W when a fridge starts.
Can the EcoFlow River 2 Pro run a CPAP overnight?
Yes. A CPAP without a heated humidifier averages about 35 W, so the EcoFlow River 2 Pro runs it for about 18 h 39 min: roughly 2 nights of 8 hours on the AC outlets. Using a DC cable instead of the AC outlet stretches that further. Turning on the heated humidifier cuts runtime sharply.
Can the EcoFlow River 2 Pro run a space heater?
No. A space heater on high draws about 1,500 W, more than the EcoFlow River 2 Pro's 800 W output. Use an electric blanket instead: it keeps you warm on a small fraction of the power.
How long does the EcoFlow River 2 Pro take to charge with solar?
Its solar input tops out at 220 W. With about 300 W of panels in strong sun, a full 0–100% charge takes roughly 3 h 29 min of peak sun. Smaller panels, clouds or a low sun angle take proportionally longer.
How much of the EcoFlow River 2 Pro's 768 Wh can I actually use?
On the AC outlets, plan on about 85%, or roughly 653 Wh. The rest is lost turning battery power into household AC. The DC and USB ports skip that step and deliver a little more.
