For smart power backup at home and portable power on the road, look to the RIVER 3 Max Portable Power Station from EcoFlow. At home, the compact and lightweight power station can function as a fast-responding UPS for essential electronics and appliances. The 286Wh capacity offers 600W of output for up to 21 minutes or up to 1200W with X-Boost, which allows you save work and power down your PC or continue to run your refrigerator in a power outage. With the included EB300 battery, you can expand that capacity to 572Wh. When camping or on a trip, you can grab the built-in handle and take that power with you. AC, DC, USB-C, and USB-A ports supply power to a wide variety of devices, and you can use the mobile app to monitor the battery and get alerts wherever you are.

Power Output

The RIVER 3 Max has one front and two rear 3-prong outlets, a DC outlet, two USB-A ports, and a USB-C port. You can use them to power everything from household appliances or mobile devices. The two rear AC ports are ideal for setting up the RIVER 3 Max as a UPS at home and easily hiding the cabling. With the additional EB300 battery, you get one additional USB-C port for up to 140W of power output directly from the EB300’s 286Wh of capacity.

Fast UPS

When used at home as a UPS, the pro-grade sub-10ms automatic switchover time won’t affect currently running electronics if the power goes out. This allows you to save your work on a PC and protect sensitive devices from damage.

Get Notified of Outages

Smart outage alert features within the RIVER 3 Max notify you via the mobile app and EcoFlow software if the power goes out while the power station is plugged in. The power station’s PC and NAS-compatible data interface works with the software to automatically save data if the battery gets too low.

Mobile App Control & Monitoring

Using the EcoFlow mobile app, you can check the power station’s battery health and charging status, as well as customize various settings, such as speed control, power-saving mode, low-battery alerts, and more. Connection can be made via Bluetooth and Wi-Fi, with Wi-Fi also allowing for remote control of the RIVER 3 Max when you’re not at home.

Four Charging Options

You can use four different methods to recharge the RIVER 3 Max. Included are an AC charging cable, which can recharge the battery in up to an hour, and a car charging cable for mobile use. Optional methods include a solar panel that can output up to 220W for a full recharging in approximately 1.5 hours, or a gas generator, which can take up to an hour for a full recharge.

X-Guard Battery Protection

EcoFlow’s X-Guard technology offers cloud-based battery monitoring and battery protection. Over 40 safety measures work to protect against a variety of anomalies, such as those related to short circuits, voltage, and temperature.
