-6% Sale858Wh LiFePO4 battery with 600W continuous output (1200W X-Boost), 220W solar input, and sub-10ms UPS transfer for silent, reliable backup.
The EcoFlow RIVER 3 Max Plus combines the RIVER 3 Plus base unit with the modular EB600 expansion battery to deliver 858Wh of long-lasting energy storage. Built specifically for frequent load-shedding, field workstations, sensitive electronics, and outdoor power demands, it delivers 600W of clean, pure sine wave AC power with a 1200W surge overhead. Its sub-10ms auto-transfer switch protects desktop PCs, NAS drives, Wi-Fi routers, and CPAP equipment from rebooting or data corruption during grid dropouts. Unlike conventional lead-acid backups or loud fuel generators, the RIVER 3 Max Plus utilizes automotive-grade LiFePO4 (LFP) battery chemistry paired with an integrated GaN (Gallium Nitride) power architecture. This GaN circuitry minimizes energy conversion losses, optimizes thermal dissipation, and reduces fan noise down below 30 dB during continuous operation. It provides clean, uncompromised power in compact indoor living rooms, bedside setups, or mobile workspaces without vibration, emissions, or excessive heat.
Zener Authenticity Promise: All sitemarks, models, and technical statistics are registered with the factory and verified in our physical laboratory before sale.
Stacks wire-free using secure magnetic Pogo-pin connectors, letting you scale capacity from 286Wh to 858Wh in seconds without cable clutter
Advanced GaN semiconductor inverter runs at under 30 dB acoustic level, maintaining low internal operating temperatures and higher DC-to-AC conversion efficiency
Eliminates power interruption instantly when mains power cuts out, preventing unscheduled shutdowns for computers, servers, and medical gear
High-density lithium iron phosphate cells retain over 80% original capacity after 3,000 complete charge/discharge cycles, providing up to 10 years of daily use
Integrated 11–50V, 220W solar charge controller handles rapid off-grid replenishment from portable or rooftop PV modules
The 220V/50Hz pure sine wave inverter operates standard household and office loads including laptops (Type-C 100W PD), network routers, flat-screen TVs, mini-refrigerators, LED studio lighting, and desktop workstations. Through EcoFlow X-Boost algorithm technology, the station also powers pure
To use the unit as a dedicated UPS for desktop computers or network equipment, keep the AC wall cord connected continuously and set the AC output on; the unit will power devices via grid bypass and transfer to battery in under 10ms during outages
When pairing with third-party solar panels, ensure the open-circuit voltage (Voc) stays strictly between 11V and 50V DC to prevent overvoltage safety lockouts on the MPPT port.
For storage longer than 3 months, discharge the battery to around 50–60% and store it in a dry environment between 15°C and 25°C to preserve long-term LiFePO4 cell health.
Keep the bottom and side intake vents clear of dust and obstruction by leaving at least 10 cm of clearance around the chassis to maintain optimal GaN passive thermal flow.
A1: Yes, the unit functions as a pro-grade UPS with a transfer speed of under 10 milliseconds, which is fast enough to keep desktop computers, Wi-Fi routers, and NAS units running without rebooting
A2: The LiFePO4 chemistry provides more than 3,000 complete charge cycles to 80% original capacity, ensuring over 8 to 10 years of regular use alongside superior thermal and chemical safety compared to standard lithium-ion batteries
A3: Yes, the RIVER 3 Plus functions as a standalone 286Wh power station when detached from the 572Wh EB600 extra battery, giving you a lightweight 4.7 kg option for mobile trips
A4: It continuously powers devices rated up to 600W such as laptops, LED monitors, Wi-Fi routers, CPAP machines, and small blending tools, while resistive heating appliances up to 1200W are supported via X-Boost mode
A5: It recharges from 0 to 100% in approximately 2.3 hours using standard 220V AC wall power, or in 4.5 to 5 hours using a 220W solar panel under optimal direct sunlight
