Q: How long does it take to fully charge the EcoFlow power station using AC power?

Q: What type of battery does the EcoFlow power station use?
A: The EcoFlow RIVER 2 Max uses a Lithium Iron Phosphate (LiFePO4) battery.

A: The EcoFlow RIVER 2 Max can output up to 1000W of power.
Q: What is the maximum runtime of the EcoFlow power station at full load?

A: 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.
A: Charging the EcoFlow River 2 Max with the Foldable 45W Solar Panel would take approximately 6-12 hours, depending on factors like sunlight intensity and panel positioning. Yes, you can use the River 2 Max while it's charging, but it's best to avoid using high-power devices during this time to ensure efficient charging.
A: 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.
