EcoFlow RIVER Max Portable Power Station (576 Wh) — a portable power station from the EcoFlow brand in the Power Independence > Portable Power Stations category. The RIVER Max combines a modular design, high-speed charging with X-Stream technology, and multi-functional outputs, making it a versatile solution for travel, camping, outdoor work, and as a backup power source for home use.

The station's capacity is 576 Wh with the extra battery connected; in the basic configuration — 288 Wh. The device is equipped with two AC outlets with a nominal output power of 600 W in standard mode, while thanks to the X-Boost function, some appliances can receive a peak power of up to 1800 W (the manufacturer also indicates a realistic X-Boost operating range of up to 1200 W and recommends checking appliance compatibility within 600–1200 W).

The inverter provides a pure sine wave, and the RIVER Max can power up to 9 devices simultaneously. EcoFlow X-Stream technology ensures ultra-fast energy replenishment: 0 to 80% charge in less than 1 hour, full charge — in approximately 1.6 hours (96 minutes) when connected to a standard AC outlet. For comfortable use, a "Quiet Charging" mode is available, which can be activated via the mobile app.

Modular Design and Portability

The RIVER Max features a removable extra battery: the basic battery — 288 Wh, the additional module doubles the total capacity to 576 Wh. When the extra battery is removed, the device's weight decreases by approximately 2.5 kg (5.5 pounds), which increases portability during travel or short hikes.

Solar and Car Charging

The station can be quickly charged from solar panels: a full charge takes approximately 3–6 hours when connecting two 110 W panels, or 4.8–9.6 hours when using one EF 160 W panel, depending on lighting conditions. The EcoFlow RIVER MPPT controller supports an open-circuit voltage of 10–25 V, a maximum current of 12 A, and a maximum power of 200 W. A Solar Connector to XT60 cable is included. Car charging allows the station's energy to be replenished in approximately 6.5 hours using the standard car adapter.

Practical Capabilities

The RIVER Max is suitable for charging mobile phones, tablets, drones, coffee makers, and other household appliances: according to the manufacturer, the capacity is enough to charge a phone up to 42 times, recharge a drone 6 times, or brew up to 24 cups of coffee. The station can act as a basic UPS (uninterruptible power supply), but it is recommended to check compatibility and conduct testing before connecting critical equipment.

Frequently Asked Questions

• What is the difference between RIVER, RIVER Max, and RIVER Pro? In short: RIVER is suitable for light power with expandability; RIVER Max comes standard with an extra battery that can be removed for easier portability; RIVER Pro is designed for even greater capacity and power needs.
• Can RIVER Max be controlled remotely? Yes. Connect the station to the EcoFlow mobile app, enable Wi-Fi on the device, and add the station to the app for monitoring and remote control.
• Is the station suitable for powerful appliances? Yes, thanks to X-Boost, RIVER Max can power appliances with high power consumption (up to 1800 W recorded for some devices), but the manufacturer warns that X-Boost is effective within up to 1200 W for some types of equipment; always check compatibility before connecting.
• Are solar panels supported? Yes. Connecting two 110 W panels allows the station to charge significantly faster (3–6 hours depending on conditions).
• Can RIVER Max be used as a UPS? RIVER Max supports basic UPS functionality, but for critical equipment (servers, workstations), prior compatibility testing is required.

Attention: the stated weight, operating time, dimensions, and other parameters may have measurement errors. Operating time depends on operating conditions, connection method, load size, and ambient temperature. Part of the battery's energy is consumed to power the device's internal modules.
