At a Glance
This comparison targets buyers weighing two popular mid-capacity portable power stations for home backup, off-grid use, or emergency preparedness. The DELTA 2 Max pulls ahead on raw capability: 2048 Wh of LFP battery capacity versus 1,516 Wh of NMC in the Yeti 1500X, paired with 2,400W of running power and 4,800W surge compared to 2,000W and 3,500W. That larger reservoir and higher output translated into 45 of 53 devices supported versus 43 for Goal Zero's unit.
Longevity is a major gap as well. EcoFlow's LFP cells are rated for 3,000 charge cycles, six times the Yeti's 500-cycle NMC pack. Solar users also benefit from 1,000W max input on the DELTA 2 Max, nearly double the Yeti's 600W ceiling.
The tradeoff is weight: at 50.7 lbs the EcoFlow is about five pounds heavier, which matters if portability ranks high on your list.
