At a Glance
This comparison targets buyers weighing a compact, lighter portable unit against a high-capacity home backup system. The EcoFlow DELTA (Gen 1) delivers 1800W of running power from a 1260 Wh NMC battery and weighs just 30.9 lbs, making it easy to move between job sites, campsites, and tailgates.
The Zendure SuperBase V4600 operates in a different class entirely: 3800W of running power, 4608 Wh of LFP storage, expandable capacity, and a 1 ms UPS transfer for keeping critical loads online during outages. It also accepts up to 1500W of solar input versus 400W for the DELTA.
In device compatibility testing across 53 appliances, the SuperBase V4600 powered 43 while the DELTA handled 40. The tradeoff is significant: the Zendure tips the scale at 121.3 lbs and is not a grab-and-go option.
