Product Overview

The EcoFlow RIVER 3 UPS is designed to provide compact backup power for essential low-wattage electronics and selected small appliances.

Its 245Wh capacity is suitable for powering and charging devices such as Wi-Fi routers, mobile phones, tablets, laptops, cameras, lights, and other compatible electronics. The unit provides a 300W rated AC output, with a 600W surge rating and EcoFlow X-Boost support for selected appliances with power requirements of up to 600W.

The RIVER 3 UPS version includes an automatic switchover time of under 10 milliseconds. When connected correctly, it can switch selected compatible equipment from mains power to battery power during an interruption. This makes it suitable for supporting devices such as routers, desktop accessories, communication equipment, and selected low-power electronics.

Its LiFePO₄ battery is rated for approximately 3,000 charging cycles before reaching 80% of its original capacity, supporting long-term everyday use. EcoFlow’s built-in battery management and X-Guard protection systems monitor current, voltage, temperature, and other operating conditions.

The RIVER 3 UPS can recharge through AC mains power, compatible solar panels, a vehicle charging connection, or a compatible generator. AC charging can restore the battery from 0% to 100% in approximately 60 minutes, while solar charging supports up to 110W input.

With an operating noise level below 30dB, the RIVER 3 UPS is suitable for bedrooms, study areas, workspaces, offices, and other environments where quiet operation is important.

Runtime will vary according to the connected load, appliance efficiency, battery level, temperature, output method, and operating conditions.

UPS Compatibility Note

The under 10ms UPS function applies to the RIVER 3 UPS version.

Before using the unit as a UPS, confirm that the connected equipment:

• Is compatible with a portable power station or transfer-type UPS
• Does not exceed the RIVER 3 UPS output limits
• Can tolerate a transfer time of up to 10 milliseconds
• Does not require a specialised online or zero-transfer UPS
• Is connected according to EcoFlow’s operating instructions

Critical medical, server, security, industrial, or life-support equipment may require a dedicated online UPS or specialised backup power system.

Important Power Compatibility Note

Please check each device’s rated and starting power requirements before connecting it to the EcoFlow RIVER 3 UPS.

The unit provides a continuous rated AC output of 300W. Some appliances require significantly more power when starting than during normal operation.

X-Boost may allow selected compatible heating or resistive appliances rated up to approximately 600W to operate at a reduced voltage. It does not increase the unit’s continuous rated output to 600W and may not be suitable for precision electronics, compressors, motors, or voltage-sensitive appliances.

Runtime will depend on:

• Connected device wattage
• Number of connected devices
• AC or DC conversion losses
• Battery charge level
• Temperature
• Device efficiency
• Operating conditions

IP54 Protection Note

The IP54 rating applies to the internal battery pack protection, not to the complete portable power station as a fully waterproof enclosure.

The unit must not be submerged or intentionally exposed to heavy rain, standing water, or high-pressure water. Keep all ports, cables, and the unit itself dry during operation and charging.
