EcoFlow RIVER 3 Plus Portable Power Station

The EcoFlow RIVER 3 Plus Portable Power Station is a compact but significantly more powerful portable battery system designed for production equipment, mobile workstations and backup power. It combines a 286 Wh LiFePO4 battery with a 600 W pure sine-wave AC inverter, giving it twice the rated AC output of the smaller RIVER 2 while remaining easy to transport. The unit is especially useful for camera departments, small lighting setups, DIT stations and other location workflows that need more power than a basic compact battery station can provide.

 

286 Wh LFP battery with expandable capacity

 

The RIVER 3 Plus has a built-in capacity of 286 Wh and uses long-life LiFePO4 cells rated to retain more than 80% state of health after approximately 3000 cycles under EcoFlow’s specified test conditions. The system can also be expanded with a compatible RIVER 3 Plus Extra Battery. Depending on the additional battery used, total capacity can be increased to 572 Wh or up to 858 Wh, allowing the same compact power station to be adapted for longer production days.

 

600 W continuous AC output and 1200 W X-Boost

 

The integrated pure sine-wave inverter provides up to 600 W of continuous AC power, suitable for many production laptops, battery chargers, monitors, compact lighting fixtures and other electronics. X-Boost can support compatible heating or motor-driven appliances rated up to approximately 1200 W. As with other EcoFlow X-Boost systems, this feature is not intended for precision devices that require a stable full-voltage supply at their rated wattage.

 

Fast one-hour AC charging

 

The RIVER 3 Plus can recharge from 0 to 100% in approximately one hour from a suitable mains connection. EcoFlow specifies up to 360 W AC charging input for the European version. This makes it practical for productions where the station may need to be restored quickly between work periods rather than left charging for several hours.

 

Up to 220 W solar charging

 

The solar input accepts 11–55 V at up to 13 A, with a maximum solar charging power of 220 W. Under suitable conditions, EcoFlow specifies a full solar recharge in as little as approximately 1.5 hours. The same input can also be used for vehicle charging, providing another option for location crews travelling between shooting sites without reliable access to mains electricity.

 

High-power USB-C and multiple device outputs

 

The RIVER 3 Plus provides three AC outlets on the European model, two USB-A ports, one USB-C port and a 12.6 V car-style DC outlet. The USB-C port supports up to 100 W Power Delivery, making it suitable for many modern laptops as well as tablets, phones and camera accessories. The two USB-A ports provide up to 12 W each, while the DC output can supply up to 126 W for compatible 12 V equipment.

 

Professional-grade backup with under 10 ms transfer

 

One of the key upgrades over the RIVER 2 is the faster standby UPS function. EcoFlow specifies an automatic transfer time of under 10 ms when grid power fails. This makes the RIVER 3 Plus better suited to protecting compatible computers, network equipment and NAS systems from brief interruptions. A USB communication connection can also be used with EcoFlow Power Manager software for supported computer and NAS shutdown workflows.

 

Quiet operation and remote control

 

EcoFlow specifies operating noise below 30 dB under light-load conditions, which is useful for sound-sensitive environments such as interview sets, studios and quiet indoor locations. Wi-Fi and Bluetooth connectivity provide monitoring and control through the EcoFlow app, allowing the operator to check battery level, input and output power and selected system settings without constantly accessing the unit physically.

 

Compact 4.7 kg design for location production

 

Despite its higher output, the RIVER 3 Plus measures only approximately 234 × 232 × 146 mm and weighs around 4.7 kg. The compact housing and integrated handle make it easy to move between camera positions, workstations or shooting locations. It provides a useful middle ground between very small portable batteries and larger high-capacity power stations that are heavier to transport.
