At a Glance
This comparison targets buyers deciding between a portable, mid-capacity unit and a high-output home backup system. The Delta Pro Ultra delivers 6,000W of running power and 6,144 Wh of capacity, dwarfing the SOLIX C1000's 1,800W and 1,056 Wh. That gap shows up in device compatibility: the Delta Pro Ultra powered 52 of 53 tested devices, while the C1000 handled 38.
Solar input tells a similar story, with EcoFlow's system accepting up to 5,600W versus 600W for the Anker. The tradeoff is size and mobility. At 28.4 lbs, the C1000 is genuinely portable, whereas the Delta Pro Ultra weighs 182.1 lbs and is better treated as a stationary installation.
Both use LFP chemistry with similar cycle ratings (3,000 vs. 3,200), so longevity is comparable regardless of which you choose.
