Product Description

The EcoFlow RIVER 3 UPS is a compact portable power station designed to provide convenient backup and mobile power for everyday electronics.

It combines a 245Wh LiFePO₄ battery with 300W AC output and 600W surge capability.

For selected compatible appliances, X-Boost can support loads up to 600W.

The UPS version provides an automatic transfer time of less than 10 milliseconds, making it suitable for compatible electronics that can tolerate a brief transfer when mains electricity is interrupted.

X-GaNPower technology improves energy efficiency and thermal performance, helping extend runtime for low-wattage equipment while keeping operating noise below 30dB under specified conditions.

The RIVER 3 UPS supports four charging methods: AC, solar, vehicle and generator charging.

Using AC power, the battery can recharge from 0–100% in approximately 60 minutes. Solar charging supports up to 110W input, while vehicle charging supports up to 100W.

Its LiFePO₄ battery is rated for 3,000 charging cycles before reaching approximately 80% of its original capacity.

The RIVER 3 UPS can power or charge up to five compatible devices simultaneously through its AC, USB-A, USB-C and vehicle power outputs.

What Can It Power?

The EcoFlow RIVER 3 UPS provides:

300W normal AC output
600W surge output
X-Boost support for selected appliances up to 600W

It is suitable for compatible equipment such as:

• Wi-Fi routers
• Fibre equipment
• Laptops
• Mobile phones
• Tablets
• Cameras
• LED lights
• Security cameras
• Small displays
• Selected televisions
• Portable speakers
• Small fans
• Mini refrigerators within supported limits
• Selected low-power office equipment
• Camping electronics

X-Boost is intended for selected compatible appliances and does not increase the RIVER 3 UPS's normal continuous AC output above 300W.

Please note: Actual runtime and performance will vary depending on the specific device or appliance connected, its power consumption, startup requirements, battery level and operating conditions. Higher-power devices will use the available battery capacity faster than lower-power devices.

Always check both the normal operating power and startup requirements of the connected device before use.

UPS Backup Power

The RIVER 3 UPS provides:

<10ms Automatic UPS Switchover

When connected to mains power, compatible equipment can automatically transfer to battery power when the mains supply is interrupted.

This makes the RIVER 3 UPS useful for compatible:

• Wi-Fi and fibre equipment
• Computers
• Networking equipment
• Selected NAS systems
• Security equipment
• Communication devices
• Other suitable electronics

Important: The RIVER 3 UPS is not a zero-transfer-time online UPS.

Connected equipment must be capable of tolerating a transfer time of up to approximately 10 milliseconds.

Always check the backup-power requirements of sensitive or critical equipment before use.

X-GaNPower Efficiency

X-GaNPower technology is designed to improve energy efficiency and thermal performance.

For low-wattage appliances, this can provide longer usable runtime while helping the power station operate quietly.

Under specified testing, the RIVER 3 can provide up to twice the runtime for selected low-wattage devices.

Actual runtime will depend on the connected load and operating conditions.

Battery & Protection

The RIVER 3 UPS uses LiFePO₄ battery cells rated for:

3,000 cycles to 80% capacity

X-Guard battery protection technology provides more than 40 safety measures covering current, voltage, temperature and circuit-related operating risks.

The internal battery pack carries an:

IP54 Protection Rating

The IP54 rating applies to the battery pack, not the complete portable power station.

The complete RIVER 3 UPS should not be treated as waterproof or submerged in water.
