At a Glance
This comparison targets buyers deciding between a portable mid-range unit and a high-capacity home backup system. The AC180 delivers 1,800W of running power from a 1,152 Wh LFP battery and weighs just 36.2 lbs, making it easy to move between rooms, campsites, or tailgates.
The DELTA Pro 3 operates in a different class entirely: 4,000W running output, 8,000W surge capacity, and a 4,096 Wh battery that can be expanded further with add-on storage. In device compatibility testing across 53 appliances, the Pro 3 powered 48 while the AC180 handled 39, giving EcoFlow's unit a clear coverage advantage for whole-circuit or multi-appliance scenarios.
Solar input tells a similar story, with the Pro 3 accepting up to 2,600W versus the AC180's 500W ceiling. The tradeoff is weight and mobility: at 113.5 lbs, the Pro 3 is more than three times heavier, and it lacks the AC180's 20 ms UPS switchover.
