At a Glance
This comparison targets buyers weighing a mid-capacity portable unit against a high-output home backup powerhouse. The DELTA Pro 3 doubles the AC200MAX in almost every core metric: 4,000W running output vs. 2,200W, 4,096 Wh of stored energy vs. 2,048 Wh, and an 8,000W surge rating vs. 4,800W.
In device compatibility testing across 53 appliances, the Delta Pro 3 powered 48 while the AC200MAX handled 45, giving EcoFlow's unit a wider coverage edge. Solar input capacity tells a similar story, with the Pro 3 accepting up to 2,600W compared to 900W.
Both use LFP chemistry and support expansion batteries. The tradeoff is weight and portability: the AC200MAX comes in at 61.9 lbs, roughly half the Pro 3's 113.5 lbs, making it far easier to move between job sites, campsites, or rooms.
