ECOFLOW RIVER 3 MAX PLUS

EcoFlow RIVER 3 Max Plus - Portable Backup Power with 858Wh Capacity

The EcoFlow RIVER 3 Max Plus Portable Power Station is designed for users who need portable electricity for essential electronics, home-office equipment and selected household appliances. With a combined capacity of 858Wh and a rated AC output of 600W, it provides additional stored energy for use during power interruptions, travel and outdoor activities.

The RIVER 3 Max Plus consists of the RIVER 3 Plus power station and the EB600 Smart Extra Battery. This combination increases the total battery capacity to 858Wh while retaining the core output capabilities of the RIVER 3 Plus.

858Wh Battery Capacity for Extended Runtime

The combined 858Wh capacity provides stored energy for compatible devices such as Wi-Fi routers, laptops, smartphones, LED lights and other low-power electronics. The additional capacity can extend operating time compared with the standard 286Wh RIVER 3 Plus.

Actual runtime depends on the power consumption of connected devices, inverter efficiency, operating conditions and the energy available from the battery. For the best results, calculate the combined wattage of your devices and the number of hours you need backup power.

600W AC Output with X-Boost Technology

The RIVER 3 Max Plus offers 600W of rated AC output across three AC outlets, allowing compatible devices to run simultaneously within the total power limit.

EcoFlow's X-Boost technology supports selected appliances with power requirements above the standard 600W rating, up to the advertised 1200W level under compatible conditions. X-Boost does not guarantee that every appliance rated above 600W will work normally. Always check appliance compatibility and startup power requirements before use.

LFP Battery Technology and Long-Term Durability

The system uses lithium iron phosphate (LFP or LiFePO4) battery chemistry. EcoFlow specifies a cycle life of 3000 cycles before the battery retains approximately 80% of its original capacity under stated testing conditions.

Actual battery lifespan depends on usage frequency, charging habits, storage conditions and operating temperature.

Multiple Charging Options

The RIVER 3 Plus component supports AC charging and solar input of up to 220W. Car charging and compatible generator charging provide additional options, depending on the equipment and connection used.

Charging time for the complete RIVER 3 Max Plus system depends on the battery configuration, charging source, input power and operating conditions. Solar charging performance also depends on sunlight, panel orientation and compatible panel specifications.

USB-C Charging and Multiple Device Outputs

The power station provides a USB-C port capable of delivering up to 100W to compatible devices, including supported laptops, tablets and smartphones. Two USB-A ports support additional mobile devices and accessories.

Three AC outlets provide power for compatible equipment using conventional AC plugs, while the 12V car output supports suitable DC devices. Check each device's voltage, wattage and connector requirements before connecting it.

UPS Function for Home and Office Equipment

The RIVER 3 Max Plus features a UPS switching time of less than 10 milliseconds under specified conditions. This can help maintain power to compatible computers, routers and other electronics during brief interruptions.

It should not be assumed to replace every dedicated UPS system. Confirm that the connected equipment can tolerate the specified switching time, especially for critical applications.

Portable Design for Home Backup and Outdoor Use

With a combined system weight of approximately 10.8kg, the RIVER 3 Max Plus provides a balance between increased battery capacity and portability. It is suitable for moving between rooms, workspaces and outdoor locations where backup electricity is needed.

For Nigerian homes and small businesses, it can support selected essential electronics during outages, provided their combined power consumption remains within the system's limits.
