Frequently Asked Questions

Each of the RIVER Series has its advantages. RIVER is ideal for lightweight, grab-and-go power, which you can expand with the extra battery. RIVER Max includes the extra battery by default, which you can remove to go lightweight. RIVER Pro is made for those that need even more capacity for off-grid, long haul adventures.

Yes. You can control RIVER Max using your phone. Just link to it in the EcoFlow app to control it from afar.

Yes. RIVER Max can power devices up to 1800W with our proprietary technology, X-Boost. *X-Boost can run devices that require up to 1800W, however, it’s best to test before use. Some 600W-1800W appliances with strict voltage requirements may not function (eg. air compressors).

Yes. You can connect up to 2 sets of 110W solar panels to sustainably charge your RIVER Max in under 3 hours.

It can be an emergency power source (EPS), which will have the same result as UPS for most electronics. Here's the difference. When your RIVER Max is plugged into the wall, anything plugged into it gets power from the grid, not its battery. If power from the grid stops, RIVER Max automatically switches to its battery supply mode within 30 milliseconds. That means anything connected will not have power for 30 milliseconds, which may mean sensitive electronics like desktop computers and data servers turn off. Test your devices individually to see if they need UPS to stay powered.
