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).
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.
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.

EcoFlow RIVER Max Portable Power Station

Have been testing it at home and timing the unit with different appliances that I use when out camping. The times are varied depending on what I use (DC or 12V and I am no tech-head or even tech savvy) and have found the unit will definitely meet all of my needs. I have a 50l Brass Monkey fridge/freezer which is not power hungry anyway and I can safely use it for 4 days solid with constant use. It will also keep phones and laptops charged during that time which is the main reason I purchased. Pricey...but so worth it! Will purchase the solar panels next!

Excellent Batt for the price

So far, it worked as expected. We are using it only for camping and it has exceed our initial thoughts. Planing to get one or two more ( camping and astronomy sessions) and I let you know future results.

Works great with CPAP

Used the River Max and 160W solar panel for a week long camping trip in Colorado (Moraine Campgrounds near Estes Park-A66). Powered a Respironics Dreamstation CPAP at 13cmH2O at night and Bodega 53qt refrigerator freezer during the day. River Max connected to the solar panel during the day. CPAP dropped the battery to about 80%. Solar panel kept the battery topped off with the Bodega in an "eco" mode. Excellent combination running without a powered campsite.

Great little unit!

This is an awesome unit. Charges super fast and runs my dc frige all day with ease. The screen gives you lots of information. Thinking of buying a bigger one now, I'm hooked lol.

River Max Review

The River Max has met all my expectations. It charges quickly from AC and charges well from Solar using an ITEHIL 100W solar panel. On a mostly cloudy day it charged from 0% to 20% charge in just over two hours.

The feature that I like the most is the ability to remove the battery from the bottom of the unit. While this brings the capacity down to 288Wh it also reduces the weight from 8kg to 5.5kg. This helps keep my weight down when in the field for photography while retaining the ability to use the full capacity while on extended bike trips.
