At a Glance
This comparison targets buyers choosing between a mid-capacity portable power station and a larger, more capable unit for home backup or extended off-grid use. The SOLIX C1000 delivers 1800W of running power and 1056 Wh of capacity, more than double the 800W output and 768 Wh capacity of the RIVER 2 Pro.
That gap shows up clearly in device compatibility: the C1000 powered 38 out of 53 tested devices, while the RIVER 2 Pro handled 22. Solar recharge speed favors Anker's unit as well, accepting up to 600W of panel input for a full charge in roughly 3.8 hours versus 220W max and about 5 hours for EcoFlow's model.
The C1000 also adds expandable battery support and a 20ms UPS transfer for light home-backup duty. The tradeoff is weight: at 28.4 lbs, the C1000 is over 10 lbs heavier than the 18.3 lb RIVER 2 Pro, a real factor for hikers and car campers packing tight.
