Q: QuestionCan I connect a sump pump?

Asked 6 months ago by Juan.

• A:Answer The River 2 Max has a capacity of 512Wh, with a continuous AC output of 500W and a surge power of 1000W. Most sump pumps typically require 800–1500W to run, with even higher surge demands. Unfortunately, the River 2 Max won’t be able to support this load. We recommend considering a power station with a higher output and capacity for your sump pump needs.

Q: QuestionHow smooth is the output waveform, is this a true sine wave or stepped inverter?

Asked 2 weeks ago by MortallyWounded.

• A:Answer The AC inverter in the RIVER 2 MAX produces a true/pure sine wave output. This means the AC power it delivers is smooth and consistent, similar to household mains power — not a stepped or modified waveform.

Q: Questionhow long can it power a T-mobile router and an Hp all in one computer?

Asked 2 weeks ago by Tommy.

• A:Answer The EcoFlow RIVER 2 Max has a 512Wh capacity, with about 85–90% usable energy after efficiency losses. A typical T-Mobile router usually draws around 8–15 watts, so on its own it could run for approximately 30-35 hours (close to two days). An HP all-in-one computer generally consumes much more power, often between 60–150 watts depending on the model and usage. If your HP averages around 100 watts and the router uses about 10 watts (110 watts combined), you could expect approximately 4 hours of runtime. If the computer draws closer to 150 watts, runtime would drop to around 3-4 hours. Actual performance will vary based on the exact models and how heavily the computer is being used.

Q: QuestionCan this power a crock pot that may require 6-8 hours to cook something as well as possibly also do a power bank charge as well as a phone charge

Asked 2 months ago by Bestbuyenthusiast.

• A:Answer The EcoFlow RIVER 2 Max (512Wh) can power a crock pot and also charge a phone or power bank at the same time, as long as the crock pot stays within the unit’s power limits. However, running a crock pot for 6–8 hours on a single charge is unlikely. Most crock pots use a steady amount of power, and the 512Wh battery will typically provide only a few hours of runtime, depending on the cooker’s wattage. Charging a phone or power bank uses very little power compared to the crock pot, but it will slightly reduce the overall runtime.
