Why Choose This EcoFlow Power Station?

Fast UPS Switchover

When mains power is interrupted, the RIVER 3 UPS switches compatible connected equipment to battery power in less than 10 milliseconds, helping routers, fibre equipment and computers stay on during a power cut.

Recharges in About an Hour

X-Stream AC charging takes the battery from 0–100% in approximately 60 minutes, so the unit is ready again quickly between outages.

Long-Life LiFePO₄ Battery

The lithium iron phosphate battery is rated for 3,000 charge cycles before reaching approximately 80% of its original capacity.

Four Ways to Charge

Recharge from a wall socket, compatible solar panels (up to 110W), a vehicle (up to 100W) or a compatible generator.

Quiet, Efficient Operation

X-GaNPower technology improves efficiency and thermal performance, with operating noise below 30dB under specified conditions.

Compact and Portable

At approximately 3.55kg and 255 × 212 × 113mm, the RIVER 3 UPS is easy to move between rooms, the office and the car.

Product Description

Compact Backup Power for Everyday Essentials

The EcoFlow RIVER 3 UPS 245Wh Portable Power Station combines a 245Wh LiFePO₄ battery with 300W pure sine wave AC output and 600W surge capability, making it a practical backup solution for compatible low-power electronics.

For selected compatible appliances, X-Boost can support loads up to 600W. X-Boost does not increase the normal continuous AC output above 300W.

Less Than 10ms UPS Switchover

When connected to mains power, the RIVER 3 UPS automatically transfers compatible equipment to battery power in less than 10 milliseconds if the supply is interrupted.

It is not a zero-transfer-time online UPS. Connected equipment must be able to tolerate a transfer of up to approximately 10 milliseconds.

Fast and Flexible Charging

Using AC power, the battery recharges from 0–100% in approximately 60 minutes. Solar charging supports up to 110W input, vehicle charging up to 100W, and a compatible generator can also be used.

Multiple Outputs

One AC outlet, two USB-A ports, one 100W USB-C port and a vehicle power outlet allow the RIVER 3 UPS to power or charge up to five compatible devices simultaneously.

Battery Protection

X-Guard battery protection monitors current, voltage and temperature, and the internal battery pack carries an IP54 protection rating. The IP54 rating applies to the battery pack only, not the complete power station.

App Control

The RIVER 3 UPS connects to the EcoFlow app for compatible monitoring and control functions.
