Long-life LiFePO4 battery
RIVER 3 Plus uses LiFePO4 cells that retain at least 80% of their capacity for over 10 years. Unlike lead-acid UPS systems, it doesn’t need frequent replacement, reducing long-term costs and concerns related to outage risks.
Fast <10 ms UPS switching
Automatic switching in under 10 milliseconds keeps desktops, NAS units, routers and other sensitive devices running during interruptions. The pure sine-wave 600 W output is ideal for home offices, small servers and entertainment setups.
Up to four days of backup power
With its 286 Wh capacity, it can keep a 3 W Wi-Fi router running for up to 35 hours or a 600 W desktop for about 21 minutes. With the expansion battery, total capacity grows to 858 Wh, covering longer outages and everyday essentials.
Fast 1-hour charging
Typical UPS units often need an entire night to recharge. RIVER 3 Plus refills from 0–100% in about one hour, so you’re ready for sudden outages quickly—a strong advantage in areas with frequent power cuts.
Four charging methods
Besides wall charging, RIVER 3 Plus can be charged from a 12 V car socket, a generator or compatible solar panels. This reduces dependence on the grid and keeps backup power available even during extended outages or outdoor use.
UPS management with Power Manager
When connected via USB-B, the Power Manager software lets you monitor device status and outage logs. It provides low-battery warnings, helps prevent data loss and can trigger automatic shutdown of a computer or NAS.
Smart control and LCD display
The colour LCD shows UPS status, battery level, input/output power and settings. With the EcoFlow app, you can remotely check battery health, adjust charging speed, schedule charging and receive low-battery alerts.
Integrated emergency light
The built-in LED light turns on automatically during a power cut, helping you navigate the room and manage equipment without searching for a separate flashlight.
Lightweight and quiet
Weighing about 4.7 kg, RIVER 3 Plus is suitable for home use or travel. Its compact design fits in a closet, car or backpack, and the sub-30 dB noise level makes it unobtrusive in bedrooms or offices.
Seven outputs for different devices
Three UPS-protected AC outlets keep sensitive electronics running. USB-C and USB-A ports handle phones and tablets, while the car-style 12 V port powers portable fridges, pumps and other 12 V gear.
