EcoFlow River 3 Max Portable Power Station

The EcoFlow River 3 Max is a powerful combination of the RIVER 3 Plus power station and an additional battery, offering a total capacity of 572 Wh. With a rated output of 600 W (boostable up to 1200 W using X-Boost mode), it can easily power a wide range of devices. Thanks to the next-generation GaN (gallium nitride) semiconductors, the device achieves excellent energy efficiency and reduced heat loss. Its lightweight and durable design makes it ideal for travel. The built-in UPS function provides backup power in under 10 ms during emergencies.

Reliable Power for Essential Devices
With up to 600 W output (or 1200 W in X-Boost mode), the RIVER 3 Max can handle most everyday appliances — from smartphones and laptops to lamps and portable fridges.

Benefit from GaN Technology
Unlike traditional silicon-based models, RIVER 3 series devices use advanced GaN semiconductors, offering better conductivity, higher efficiency, and lower heat buildup. With a noise level of just 30 dB (comparable to a whisper), the station operates silently — even at night.

Multiple Output Ports Available
RIVER 3 Max features three 230 V AC outlets (600 W, 1200 W peak), two USB-A ports (total 24 W), one 100 W USB-C port, one 140 W USB-C port, and a 12.6 V, 126 W car socket. You can conveniently charge phones, laptops, lights, and more at the same time.

Built-In UPS for Emergency Power
Equipped with an integrated UPS, the station can switch to backup power in under 10 ms. This ensures uninterrupted operation of critical devices like PCs or refrigerators. It can also notify your NAS or PC server to safely save data and shut down when battery levels run low.

Versatile Charging Options
You can charge the RIVER 3 Max in just 1.5 hours via AC outlet or generator. It also supports solar charging (up to 220 W), car charging, and even USB-C charging. This makes it a great choice for both home and outdoor use.

Long-Lasting and Durable
The built-in LiFePO4 battery delivers up to 3000 charge cycles (to 80% capacity), providing up to 10 years of use. X-Guard technology offers protection from overcharging, short circuits, overvoltage, and more. The battery is IP54-rated (dust and splash resistant), and the station is drop-resistant from 1.5 meters.

Convenient Operation
Compatible with the EcoFlow app via Wi-Fi and Bluetooth, the device allows remote control and monitoring of charge level, power usage, and remaining run time. It also features a built-in color display for quick access to key stats.

High Capacity, Compact Design
Despite its 572 Wh capacity, the RIVER 3 Max weighs just 8 kg and measures only 234 × 224 × 255 mm. It's compact enough to take anywhere — whether you're in the garden, camper van, or on a camping trip.
