-8% SaleCompact 286Wh LiFePO4 power station delivering 600W pure sine output, <10ms UPS protection, and expandable capacity up to 858Wh.
The EcoFlow RIVER 3 Plus is a high-output, expandable portable power station and pro-grade uninterruptible power supply (UPS) engineered for demanding desktop workstations, sensitive home electronics, field creators, and emergency load-shedding backup. Powered by an upgraded 286Wh Lithium Iron Phosphate (LiFePO4) core and next-generation Gallium Nitride (X-GaNPower) semiconductor architecture, this unit doubles the continuous AC output of standard compact units to a full 600W pure sine wave. Designed to eliminate downtime during abrupt voltage dips and grid dropouts, the RIVER 3 Plus delivers true pro-grade automatic transfer switching in under 10 milliseconds. This guarantees that multi-bay Network Attached Storage (NAS) units, custom PC towers, gaming consoles, and medical hardware stay energized without restarting. For extended field runs or prolonged blackouts, its modular top-stacking interface allows wireless capacity expansion up to 858Wh without external cables.
Zener Authenticity Promise: All sitemarks, models, and technical statistics are registered with the factory and verified in our physical laboratory before sale.
Runs high-drain electronics with 600W nominal output and utilizes dynamic voltage management to handle resistive appliances up to 1200W without tripping overload protections.
High-speed internal relay switches from grid bypass to battery inverter in under 10ms, shielding delicate server hardware, modems, and PC work sessions from data corruption.
Features integrated Pogo Pin connectors on top of the chassis to magnetically stack an extra battery (EB300 or EB600), scaling storage seamlessly from 286Wh to 572Wh or 858Wh.
Advanced Gallium Nitride topology cuts internal switching resistance and idle draw, delivering up to 2x extended operational runtime for devices drawing under 100W.
Recharges from 0 to 100% in 60 minutes via standard 220V grid AC power, or accepts up to 220W of solar input to achieve a full recharge in 1.5 hours.
Seamlessly powers 600W workstation PCs, multi-monitor desk setups, NAS systems, and Wi-Fi 6 mesh routers during load shedding.
Direct DC fast-charging for camera rigs, video lighting, audio receivers, and high-drain USB-C PD laptops via the 100W Type-C interface.
Built-in multi-mode LED ambient bar provides broad area illumination without requiring external lamps or draining standalone power.
Accepts 11–30V / 11–55V solar input up to 220W (13A max), integrating directly with portable folding solar panels for independent off-grid field recharge.
For maximum battery lifespan in continuous 24/7 desktop UPS configurations, configure the AC charge ceiling to 85% in the EcoFlow app to limit high-voltage cell dwell stress.
Take advantage of the 100W USB-C PD port to power modern Type-C laptops directly, bypassing the 220V inverter circuit to avoid DC-to-AC conversion losses and gain up to 15% more runtime.
When expanding capacity with an EB300 or EB600 extra battery, power down the RIVER 3 Plus before aligning the Pogo Pin contacts to ensure smooth BMS synchronization.
If pairing with third-party solar panels, confirm that the open-circuit voltage (Voc) stays below 55V DC to ensure complete compatibility with the internal MPPT charge controller.
A1: Yes, the EcoFlow RIVER 3 Plus provides a sub-10 millisecond UPS switchover that prevents gaming PC power supplies from dropping, while delivering up to 600W continuous output. A typical 300W–400W gaming rig can run for approximately 35 to 45 minutes on the base battery, giving ample time to save progress or finish matches.
A2: The RIVER 3 Plus expands capacity wirelessly using top-mounted Pogo Pin contacts that dock directly to the EB300 (286Wh) or EB600 (572Wh) extra battery packs without external cables. Stacking the EB600 increases the total energy storage to 858Wh, tripling the runtime for connected loads.
A3: The RIVER 3 Plus delivers 600W continuous output (compared to 300W on the standard RIVER 3), supports solar input up to 220W (vs 110W), features modular battery expansion up to 858Wh, and includes a built-in multi-mode LED light bar.
A4: The EcoFlow RIVER 3 Plus recharges from 0% to 100% in 60 minutes from a standard 220V wall socket using X-Stream fast charging. When connected to a 220W solar panel in direct sunlight, it recharges completely in approximately 1.5 hours.
A5: Yes, the EcoFlow RIVER 3 Plus can operate resistive heating appliances up to 1200W using built-in X-Boost technology. X-Boost steps down the operating voltage to limit current draw, allowing basic heating equipment to function safely without tripping the power station's circuit breaker.
