About EcoFlow RIVER Max

What is the difference between RIVER, RIVER Max and RIVER Pro?

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.

Can RIVER Max handle high-wattage appliances?

Yes. RIVER Max can power devices up to 1200W with our proprietary technology, X-Boost. *X-Boost can run devices that require up to 1200W, however, it’s best to test before use. Some 600W-1200W appliances with strict voltage requirements may not function (eg. air compressors).

Can I control RIVER Max remotely?

Yes. You can control RIVER Max using your phone. Just connect to the EcoFlow app to control from afar. Here’s how: Step 1: Make sure the EcoFlow App is connected to RIVER Max. Step 2: Make sure RIVER Max is on. Step 3: Make sure your device’s WiFi is turned on Step 4: Find your device in the app. Then, you can start controlling your RIVER Max remotely.

Can I use Solar Panels with RIVER Max?

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

Can RIVER Max be used as an Uninterruptible Power Supply (UPS)?

RIVER Max supports entry-level UPS functionality. Make sure to perform multiple tests to confirm compatibility before connecting devices such as data servers and workstations with RIVER Max.
