EcoFlow River 3 Plus Portable Power Station for Home Backup and Camping

286Wh Capacity with Fast AC Recharge:

The EcoFlow River 3 Plus delivers 286Wh of capacity from a LiFePO4 battery rated for 3,000 charging cycles - approximately 10 years of everyday use before capacity drops to 80%. Using X-Stream technology, it recharges fully from mains AC in just 60 minutes.

600W Output and X-Boost for High-Draw Appliances:

Three AC outlets provide a combined 600W rated output, with X-Boost technology extending surge capacity to 1,200W for higher-draw devices that would otherwise exceed the unit's rated limit. A single USB-C port delivers up to 100W, two USB-A ports provide up to 12W each, and a car output supplies 126W - covering a wide range of devices from smartphones and laptops to portable coolers and small appliances.

Pro-Grade UPS with Sub-10ms Switchover:

The River 3 Plus includes a built-in UPS function that switches to battery power in under 10 milliseconds when mains supply is interrupted, protecting PCs, NAS drives, and routers from unexpected shutdowns. A dedicated USB-B to USB-A data communication port allows UPS monitoring software on compatible PCs and NAS devices to receive live status updates. Operating noise is below 30 dB, measured at 0.5 metres.

Multiple Charging Inputs Including Solar:

Beyond the 360W AC input, the River 3 Plus accepts solar panels up to 220W (11-55V, 13A) for a full charge in as little as 1.5 hours, and a car input up to 220W for charging on the road. X-GaNPower Technology improves energy efficiency for low-wattage appliances, extending runtime beyond what the raw capacity figure suggests - for example, a 3W Wi-Fi router can run for up to 35 hours on a single charge.

Expandable Capacity and App Control:

The River 3 Plus connects wire-free to the EB300 (286Wh) or EB600 (572Wh) extra battery modules, scaling total capacity to a maximum of 858Wh without any additional cabling. Wi-Fi and Bluetooth connectivity allow full monitoring and control via the EcoFlow App, including real-time power flow, remaining runtime, and charge settings.

Setup and Care

Getting Started:

Plug the included AC charging cable into a standard mains socket to begin charging. The River 3 Plus charges from 0 to 100% in 60 minutes, so it is ready to use in under an hour from first unboxing. Download the EcoFlow App and connect via Wi-Fi or Bluetooth to monitor charge status and configure settings.

Charging via Solar:

Connect a compatible solar panel (11-55V, up to 220W) using an XT60 solar charging cable to the solar input port. Position panels in direct sunlight for the fastest charge times - the River 3 Plus can reach full capacity from solar in approximately 1.5 hours under ideal conditions. The car charging cable included in the box also allows top-up charging while driving.

UPS Setup:

For UPS use, connect your PC or NAS to the River 3 Plus using the included USB-B to USB-A communication cable. This allows compatible monitoring software to receive live status data and initiate a safe shutdown if mains power is interrupted. The UPS switchover time is under 10 milliseconds, which is fast enough to protect most sensitive equipment.

Storage and Long-Term Care:

Store the River 3 Plus within the -10°C to 45°C temperature range when not in use. For long-term storage, EcoFlow recommends keeping the battery between 30% and 60% charge. The LiFePO4 battery chemistry is well-suited to partial charge cycles and does not require full discharge before recharging.
