At a Glance

This comparison targets buyers shopping for a compact, sub-300W portable power station for light loads like phones, laptops, lights, and small appliances. The RIVER 2 edges ahead on device coverage, powering 17 out of 53 tested devices versus 15 for the SOLIX C300.

EcoFlow's unit also delivers a 600W surge rating, double the C300's 300W surge, which helps it start momentarily demanding loads the Anker simply cannot handle. Solar recharge favors the RIVER 2 as well: a 110W max input fills its 256 Wh battery in roughly 3.3 hours, while the C300's 100W input needs about 4.1 hours to top off 288 Wh.

The tradeoff is switchover speed. Anker's 10 ms UPS response is three times faster than EcoFlow's 30 ms, a meaningful difference if you plan to use the station as a mini home backup for sensitive electronics.

The Bottom Line

Pick the SOLIX C300 if fast UPS switchover matters most, since its 10 ms response better protects sensitive gear during outages, and its slightly larger 288 Wh battery adds a small capacity cushion. Go with the RIVER 2 if broader device compatibility, stronger surge handling at 600W, and faster solar charging are higher priorities. With a score of 33 to 28 and two extra devices powered in testing, the RIVER 2 is the stronger overall pick for most portable and light backup needs.
