At a Glance
This comparison targets buyers weighing two mid-capacity LFP portable power stations for camping, tailgating, or light home backup. The DELTA 3 Plus pulls ahead on nearly every core spec: 1800W running output versus 1200W on the C800 Plus, 1024 Wh of capacity compared to 768 Wh, and a 3600W surge rating that doubles the Anker unit's 1600W ceiling.
That extra headroom translated directly into device compatibility, where the DELTA 3 Plus powered 42 of 53 tested devices versus just 24 for the C800 Plus. Solar users will notice a major gap as well.
EcoFlow accepts up to 1000W of solar input, more than three times the C800 Plus's 300W max, yet both units hit a full solar charge in roughly 3.7 hours. The tradeoff is weight and simplicity: at 24 lbs, the C800 Plus is about 3.6 lbs lighter and may suit users who prioritize portability over raw power.
