EcoFlow RIVER 2 Powerstation 256Wh packs a 256Wh LFP battery into a portable unit with 300W of continuous AC output. The US model weighs approximately 7.7 lb and measures 9.6 x 8.5 x 5.7 inches, according to EcoFlow's specifications.

Compact Power With Fast Charging

The RIVER 2 uses the model designation EFR600 and supports pure sine wave AC output at 120V, with two US outlets and 300W total output. EcoFlow's X-Boost mode supports up to 600W for compatible devices, while the USB-C port provides up to 60W and each USB-A port provides up to 12W.The US manual lists the EFR600 model, 256Wh capacity, 300W AC output, and 60W USB-C output.

AC input is rated at 360W, and EcoFlow lists a full AC recharge time of 60 minutes. Solar input supports up to 110W through an 11-30V, 8A connection, while car charging supports 12V or 24V input at up to 100W.EcoFlow describes the 300W running output, 600W X-Boost capability, and one-hour AC charging time.

Battery Design And Connections

The battery uses lithium iron phosphate chemistry, commonly abbreviated LFP. EcoFlow rates it for 3,000 cycles while retaining at least 80% capacity, giving the power station a different battery profile from smaller lithium-ion units designed mainly for occasional emergency use.

The connection layout covers two AC outlets, two USB-A ports, one USB-C input and output, and a 12V DC output rated at up to 100W. Wi-Fi and Bluetooth support allow app control, while the manual specifies an operating discharge range from 14°F to 113°F.

EcoFlow lists the RIVER 2 at $239 on its US product page as of 09/23/2026. Best Buy also lists the 256Wh model at $239, linking the price to the exact US capacity rather than to the larger RIVER 2 Max or RIVER 2 Pro models.$239 price and 256Wh capacity are listed by Best Buy for the US model.

Where The RIVER 2 Fits

Compared with the RIVER 2 Max, the RIVER 2 carries 256Wh rather than 512Wh and delivers 300W rather than 500W of total AC output. The smaller unit is therefore suited to lower-power electronics, USB charging, lights, cameras, and short-duration backup loads, while high-draw appliances require a larger power station.

The 7.7-lb body and 9.6-inch length keep the RIVER 2 below the weight and capacity listed for the larger RIVER models. Its 5-year warranty and LFP battery provide useful ownership context, but the 256Wh capacity still limits runtime for devices that draw several hundred watts continuously.

Verdict For Portable Backup

The EcoFlow RIVER 2 Powerstation 256Wh is a compact US portable power station with a documented EFR600 model, 300W AC output, 60-minute AC charging, 110W solar input, and 3,000-cycle LFP rating. It fits personal electronics, small lighting loads, and brief backup sessions better than sustained high-power operation.
