EF ECOFLOW RIVER 3 Plus Portable Power Station with EB600, 858Wh, LiFePO4

For a home office or gaming setup that needs backup power, the EF ECOFLOW RIVER 3 Plus pairs a portable power station with the EB600 extra battery. Its UPS-supported outlets switch over in under 10 ms, helping keep connected equipment powered through an interruption and giving compatible computers or NAS devices time to save data automatically when the battery is low.

The compact setup also suits camping and other off-grid situations where you need power for everyday devices. Expandable capacity and several output types make it easier to plan for more than one device at a time.

Usage tips

Connect essential home-office or gaming equipment to one of the three UPS-supported AC outlets, and use the EcoFlow software interface for compatible PC or NAS setups. LED, app and software alerts help you keep track of power status. For other gear, the station has USB-A, USB-C and car-charger outputs, so you can choose a connection that fits the device.

To extend available energy, connect the EB600 using the Pogo Pin system. The extra battery clips on for a simple connection and adds a 140W USB-C port for input and output. For recharging, use AC power for a full charge in about an hour, or a 220W solar input for a recharge in as little as about 1.5 hours. Bluetooth and Wi-Fi app control provide access to charging speed, timed charging, power-saving mode and low-battery notifications.

Benefits

The RIVER 3 Plus is designed to make backup power practical as well as portable. With the EB600 attached, the combined capacity reaches 858Wh, giving you more stored energy for a longer session or for powering several devices. X-Boost provides up to 1,200W, while the station’s steady output is 600W, this gives you a clear basis for matching connected equipment to its power needs.

For low-draw appliances under 100W, the design offers up to twice the runtime compared with the stated baseline. Its quiet operation is rated at 30 dB at 1.6 ft, a useful consideration when the station is near a desk, sleeping area or campsite. The built-in light adds a practical source of illumination, and the LiFePO4 battery is rated for 3,000 charging cycles.

Buyers highlight its functionality and portability, while opinions on power capacity and durability are mixed. The expandable battery setup is especially relevant if your use calls for more stored energy than the base station provides.

When it makes sense

A solid pick if you want one power station for both short home backup and portable use, with UPS support for a computer setup and the option to expand capacity for longer sessions. For example, at a campsite, the RIVER 3 Plus can supply power to everyday devices, while its quiet operation and built-in light add convenience around the site. For a desk setup, the fast switchover and compatible alerts focus the system on protecting connected equipment and supporting an orderly shutdown. The EB600 makes the bundle particularly useful when added capacity matters alongside portability.
