The EcoFlow RIVER 3 Max is a compact portable power station designed to deliver convenient, reliable energy for camping, outdoor activities, home backup and everyday applications. Combining the RIVER 3 Plus with an additional EB300 battery, it provides an increased total capacity of 572Wh, doubling the energy storage of the standard RIVER 3 Plus. With 600W of rated AC output and EcoFlow's X-Boost technology supporting compatible appliances up to 1200W, it offers versatile portable power in a convenient expandable design. Its compact construction makes it suitable for travelling, camping and keeping essential equipment running during unexpected power interruptions.
Flexible Power For Multiple Devices
The RIVER 3 Max delivers up to 600W of continuous AC output through three AC outlets, providing power for a variety of everyday appliances and electronics. Its X-Boost technology supports compatible heating appliances and other equipment requiring up to 1200W. Alongside its AC connections, it features two USB-A ports, a 100W USB-C port and a 12V car power outlet, allowing multiple devices to be powered and charged simultaneously. This combination of connections makes it suitable for everything from smartphones and laptops to portable equipment and essential household electronics.
Increased Battery Capacity For Extended Runtime
With a combined 572Wh battery capacity, the RIVER 3 Max provides twice the energy storage of the standard RIVER 3 Plus. Its additional EB300 battery connects using EcoFlow's wireless pogo-pin technology, creating a convenient stacked configuration without the need for additional cables or screws. The increased capacity provides longer operating times for connected appliances, making it particularly useful for extended camping trips, outdoor activities and emergency home backup. The battery system can also be expanded further by upgrading to a compatible EB600 Extra Battery, increasing total capacity to 858Wh.
Four Convenient Charging Methods
The RIVER 3 Max benefits from the RIVER 3 Plus's four flexible charging methods, including AC mains, solar, car and generator charging. EcoFlow's X-Stream technology allows the power station to recharge in approximately one hour using AC input, while its 220W solar charging capability provides an alternative for off-grid applications. Solar charging can replenish the standard RIVER 3 Plus battery in approximately 1.5 hours under suitable conditions, with additional charging flexibility available through compatible car and generator connections. This makes it easy to replenish stored energy whether at home, on the road or at a campsite.
Intelligent Backup Protection & Quiet Operation
The RIVER 3 Max incorporates a professional-grade uninterruptible power supply (UPS) with a switching time of less than 10 milliseconds, helping protect sensitive electronics against unexpected power interruptions. It is particularly useful for maintaining power to computers, Wi-Fi routers and other essential equipment. EcoFlow's advanced GaN technology improves energy efficiency, helping deliver up to twice the runtime for low-wattage appliances compared with conventional designs. Operating at less than 30dB, it also provides quiet performance suitable for bedrooms, home offices and overnight camping.
Durable Battery Technology & Smart Control
Built around lithium iron phosphate (LiFePO4) battery technology, the RIVER 3 Max is designed for dependable long-term use, with the battery system rated for up to 3000 charge cycles before retaining 80% of its original capacity. Its battery protection system incorporates IP54-rated protection against dust and water splashes, alongside EcoFlow's X-Guard technology with more than 40 integrated safety measures. Through the EcoFlow app, users can monitor battery levels, manage power settings and keep track of energy consumption, providing convenient control over their portable power supply.
