At a Glance
This comparison pairs a portable mid-range unit against a heavy-duty whole-home backup system, so the right pick depends entirely on scale. 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 campsites, tailgates, and small rooms during an outage.
The Delta Pro Ultra operates in a different class: 6,000W running output, 6,144 Wh of capacity, 12,000W surge capability, and expandable battery architecture. In device-compatibility testing across 53 products, the Delta Pro Ultra powered 52 while the AC180 handled 39, reflecting the gap in raw output.
That capability comes at a cost in portability. At 182.1 lbs, the Delta Pro Ultra is essentially a stationary appliance, and it lacks the AC180's 20 ms UPS transfer feature.
