A 70-minute charge, fed by only 220 W of Solar

The RIVER 2 Pro is EcoFlow's 768 Wh LiFePO4 station, an 18.2 lb box with four 120 V outlets.

Verdict

It suits a buyer who wants under 20 lb for camping or a fridge through a short outage and will not lean on solar.

One owner's 12 V input connector melted (June 2026) and two found the fan loud above 300 W of pass-through. Three owners in a June 2025 thread were positive, one calling it a favourite that handles a fridge's start-up surge.

OutdoorGearLab, which buys its test units, ranked it tenth of 14 with a score of 61 (January 2026), measuring 81 percent of rated capacity and a 1.3-hour charge, and faulted the loud fan and the 220 W solar cap. CNET drew 634 Wh on AC, 83 percent of rated. TheSolarLab, which earns affiliate commission on EcoFlow links, found X-Boost shut down on a 1,500 W heater and the fan pulsing inconsistently, but still called it a solid choice. GearJunkie charged it from empty in a little over an hour (April 2023).
