River 3 Max Plus

Main Features

High capacity & rated output — With the integrated extra battery the RIVER 3 Max Plus delivers up to 858 Wh of stored energy paired with a 600 W continuous AC output, allowing you to power laptops, routers, lights, and home-office equipment.

Expandability — The extra battery attaches effortlessly without cables, via a pogo-pin design, allowing you to increase runtime for longer sessions or heavier loads.

Ultra-fast full recharge — The unit supports AC input charge from 0 to 100 % in about one hour, which is much faster than many competitors, making it ready quickly for the next use.

Pro-grade UPS performance — The RIVER 3 Max Plus switches over in under 10 ms (milliseconds) in UPS mode, safeguarding sensitive electronics (PCs, NAS, routers) from disruptions or data loss.

Quiet and portable — Thanks to advanced X-GaN inverter technology and efficient cooling, the noise level stays under 30 dB, the weight is around 13.3 kg, and the form-factor makes it easy to transport for mobile, home or field applications.

Long-life, safe battery — The LiFePO₄ (LFP) battery chemistry supports 3 000+ cycles to 80 %+ capacity, offering a significantly longer lifespan and better thermal performance than standard lithium-ion batteries.

Smart monitoring and controllability — Via the EcoFlow app and the built-in LCD screen you can monitor status (battery level, input/output, runtime), receive UPS alerts, set scheduled charging and gain remote control over your power station.

Flexible inputs & outputs — Suitable for AC wall charging, solar panel input, car charging or generator input, giving you multiple ways to recharge depending on your location and situation.

Quiet expansion for home or outdoor — Whether your goal is to have reliable power during a blackout for essential devices, or to supply your mid-sized campsite or remote workstation, the RIVER 3 Max Plus bridges those use-cases elegantly.
