EcoFlow RIVER 3 Max Plus Portable Power Station

The RIVER 3 Max Plus combines the EcoFlow RIVER 3 Plus Power Station and an additional battery, offering a total capacity of 858Wh. Thanks to its output power of up to 600 watts (or up to 1200 watts in X-Boost mode), it can effortlessly power a wide range of devices. The use of next-generation GaN (gallium nitride) semiconductors ensures excellent energy efficiency and reduced heat loss. Its lightweight and durable design also make it perfect for travel. A standout feature is its UPS functionality, which enables emergency power switching in less than 10 ms.

Seamless Power for Essential Devices

The RIVER 3 Max Plus delivers 600 watts of output power and supports loads up to 1200 watts with X-Boost mode. This allows you to easily power essential devices—from smartphones and laptops to lights and travel coolers.

Harness the Power of GaN Technology

RIVER 3 series devices use innovative GaN semiconductors, delivering superior performance compared to traditional silicon-based components. Gallium nitride provides high energy efficiency and excellent conductivity while minimizing overheating risks and maintaining a compact form. A further advantage of this technology is quiet operation—the RIVER 3 Max Plus runs at just around 30 dB, comparable to a whisper or a ticking clock, allowing you to use it even at night without disturbance.

Multiple Output Options

Need to connect multiple devices? No problem! The RIVER 3 Max Plus includes:

• 3 × AC outlets (600W, 1200W with X-Boost)

• 2 × USB-A ports (12W each, 24W total)

• 1 × USB-C port (100W)

• 1 × USB-C port (140W)

• 1 × Car socket (12.6V, 126W)

This makes it easy to charge smartphones, laptops, power lights, and much more.

UPS Emergency Power Supply

Be prepared for power outages. The RIVER 3 Max Plus features UPS capability, switching to emergency power in under 10 ms. This helps keep your refrigerator or PC running uninterrupted. When the battery nears depletion, it can notify a NAS or PC server, giving enough time to save data and shut down safely—a great feature for home offices.

Versatile Charging Options

You can charge the RIVER 3 Max Plus in various ways:

• AC wall socket: full charge in about 2.3 hours

• Generator: similar time as AC

• Solar panels (up to 220W)

• Car charger

• USB-C

This flexibility ensures you can prepare the station to work in virtually any condition—ideal for travel and remote use.

Built to Last

The RIVER 3 Max Plus is equipped with a LiFePO₄ battery, offering approximately 3000 charge cycles (to 80% capacity), translating to up to 10 years of use. The X-Guard technology ensures protection against overcharging, short circuits, overvoltage, and more. The battery also has an IP54 rating—resistant to dust and water. The entire unit is drop-resistant from up to 1.5 meters, so you don't have to worry about accidental damage.

Convenient Operation

The station is compatible with the EcoFlow app, allowing remote control. You can check battery level, power usage, and runtime or adjust settings and receive alerts (e.g., during outages). The RIVER 3 Max Plus also features a built-in color display that shows key operational information at a glance.

High-Capacity, Portable Design

With a capacity of 858Wh, the RIVER 3 Max Plus can power essential devices for extended periods. Despite its capacity, it remains compact and lightweight—about 10.3 kg and dimensions of 234 × 224 × 304 mm. Perfect for the garden, camper van, or camping trips!
