At a Glance
This comparison targets buyers weighing a compact, lightweight power station against a mid-capacity unit with significantly more output. The RIVER 2 Pro delivers 800W of running power and 768 Wh of capacity, nearly tripling the C300's 300W output and 288 Wh battery.
That extra headroom shows in device compatibility: the RIVER 2 Pro powered 22 of 53 tested devices versus 15 for the C300, and every device the C300 handled, the RIVER 2 Pro handled too. Surge capacity tells a similar story, with the RIVER 2 Pro hitting 1600W compared to 300W for the Anker unit.
Solar input tops out at 220W on the EcoFlow model, cutting full recharge time to roughly 5 hours despite holding more than twice the energy. The tradeoff is portability: the C300 weighs just 9 lbs, half the RIVER 2 Pro's 18.3 lbs, and its 10 ms UPS switchover adds a layer of home backup functionality the EcoFlow lacks.
