EcoFlow RIVER 2 Pro
- 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).
Dabbsson 600L

- The Old Jarhead, which Dabbsson features on its 600L page and which links to the 600L on Amazon with affiliate links, ran it in real-world use (May 2025, about 2,100 views).
