EcoFlow River 3 Max Plus 858 Wh (Wireless) Power Station
The RIVER 3 Max Plus Wireless combines the EcoFlow RIVER 3 Plus power station with an additional battery, providing a total capacity of 858 Wh and an output power of up to 600 W (or up to 1200 W in X-Boost mode). In this version, the design has been further enhanced with a wireless charging feature, allowing you to conveniently power compatible devices without the need for cables. The use of GaN semiconductors translates to high efficiency and lower energy losses, and the lightweight, durable housing—weighing approximately 10.3 kg and measuring 234 x 224 x 304 mm—makes it easy to take the unit with you on the go. Also noteworthy is the UPS function with a switchover time of less than 10 ms, which ensures uninterrupted operation of connected devices.

Seamless power for multiple devices
The RIVER 3 Max Plus Wireless station delivers 600 W of power, and thanks to X-Boost mode, it can also handle devices requiring up to 1200 W. This means you can power not only smartphones or laptops but also more demanding equipment, such as portable coolers or computers. For example, 10 W devices can run for up to 61.1 hours, and 600 W devices for about 1 hour, providing great flexibility in everyday use.

GaN technology – efficient operation
The use of modern GaN semiconductors ensures higher energy efficiency than traditional silicon solutions. As a result, the power station operates stably, generates less heat, and maintains a compact size. An additional benefit is quiet operation at around 30 dB, allowing you to use the device even at night without disturbing your peace.

A wide selection of ports for every application
The RIVER 3 Max Plus Wireless allows you to connect multiple devices simultaneously thanks to its extensive set of ports. You have three AC outlets (600 W / 1200 W with X-Boost), two USB-A ports with a combined power of 24 W, a 100 W USB-C port, a 140 W USB-C port, and a 12.6 V 126 W car socket. This solution allows you to conveniently power both small electronics and more demanding devices.

Convenient wireless charging
The Wireless version is equipped with Qi2 wireless charging, which delivers up to 15 W and allows for charging up to twice as fast compared to older Qi solutions. The use of pogo pin technology enables instant, automatic charging of the power bank once it is plugged into the station, and a stable connection keeps it in place even during transport. This way, you can conveniently charge your smartphone or headphones, such as an iPhone or AirPods. Additionally, the built-in USB-C cable supports charging at up to 30 W, allowing you to quickly recharge mobile devices, and the power bank itself can charge up to 70% in about 33 minutes.

UPS Backup Power
Thanks to the UPS function, the station automatically switches to backup power in less than 10 ms. This solution works well for devices such as refrigerators, computers, NAS servers, or Wi-Fi routers, where even a brief power outage can be problematic. Additionally, the system can notify connected devices of low power levels, allowing you to safely save data and shut down the equipment.

Flexible and Fast Charging
The station offers several charging methods, making it easy to adapt to your current situation. Using an AC outlet, you can charge it from 0 to 100% in about 1 hour, and using solar panels, this time can be around 1.5 hours. You can also charge it from a car (about 3.3 hours) or via USB-C, which gives you more flexibility whether you’re at home or on the go.

Durability and safety for years to come
The LiFePO4 battery provides approximately 3,000 charge cycles to 80% capacity, which translates to up to 10 years of use. X-Guard technology protects the device against overcharging, short circuits, and overvoltage, while the IP54 rating protects against dust and splashes. Additionally, the design is drop-resistant from heights of up to 1.5 m, which enhances its reliability in the field.

Intuitive operation and full control
The RIVER 3 Max Plus Wireless offers convenient access to information thanks to its color display and the comprehensive EcoFlow app. You can monitor the charge level, runtime, and charging parameters, as well as adjust settings such as charging speed, schedules, and power-saving mode. Wi-Fi and Bluetooth connectivity allow you to control the device remotely, even when you’re away from home.
