At a Glance
This comparison targets buyers deciding between a midsize portable unit and a high-capacity home backup system. The DELTA 2 delivers 1800W of running power from a 1024 Wh LFP battery and weighs just 26.5 lbs, making it easy to move between job sites, campsites, and tailgates.
The SuperBase V4600 operates at a different scale entirely: 3800W of output, a 4608 Wh battery, and built-in UPS with a 1ms switchover for keeping critical home circuits live during outages. In device compatibility testing across 53 appliances, the Zendure powered 43 while the EcoFlow handled 39, giving the SuperBase V4600 an edge with heavier loads.
Solar input caps at 500W on the DELTA 2 versus 1500W on the V4600, though the smaller unit refills in roughly 3.7 hours. The tradeoff is stark: the V4600 weighs 121.3 lbs, nearly five times more than the DELTA 2, so true portability belongs to EcoFlow's side.
