Published on 09/23/2026 at 15:29 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
EcoFlow RIVER 2 Max Portable Power Station packs 512Wh into a compact black unit sized for camping, road trips, and short home outages. The US model combines 500W of AC output with a 1,000W surge rating, while its LFP battery supports 3,000 cycles to 80% capacity.
Compact Power For Travel
The unit measures 10.6 x 10.2 x 7.7 inches and weighs approximately 13.4 lb. Its 512Wh capacity places it above compact 256Wh power stations, but below the 768Wh capacity of EcoFlow's RIVER 2 Pro.
Four AC outlets provide 120V power at 500W total, with a 1,000W surge rating. The station also includes USB-A, USB-C, DC, and car outputs, giving it several charging paths for phones, laptops, lights, and other low-wattage equipment.
Fast Charging And Battery Life
EcoFlow rates the RIVER 2 Max for a 0-100% AC charge in 60 minutes. Solar input reaches 220W through an 11-50V connection, while the 100W USB-C input and output supports compatible devices directly.
The LFP battery chemistry supports 80% or more capacity after 3,000 cycles. EcoFlow lists a five-year warranty for the RIVER 2 series and app control through Wi-Fi and Bluetooth.
Price And Category Context
EcoFlow lists the US unit at $289.00 (as of 09/23/2026), while Best Buy lists the 512Wh model at $329.00 (as of 09/23/2026). The price spread reflects different sales channels and listed pricing.
Compared with the RIVER 2 Pro, the Max gives up 256Wh of capacity and 300W of AC output, but its 512Wh size and 500W inverter keep it in the midrange portable power station category. The output suits small appliances and electronics, not high-draw heating or motor loads beyond the stated limits.
Best Fit For Small Loads
The RIVER 2 Max fits users who need a portable 120V power source with fast AC charging, app monitoring, and solar compatibility. Its 13.4 lb weight supports transport, while its 500W continuous output defines the practical boundary for connected equipment.
