At a Glance

This comparison targets buyers choosing between two midsize NMC power stations for home backup and off-grid use. The Yeti 1500X delivers 2000W of running power and 3500W surge, edging out the DELTA's 1800W and 3300W ratings.

That higher output translates directly into broader device coverage: the Yeti 1500X powered 43 of 53 tested devices versus 40 for the DELTA. Goal Zero's unit also carries a larger 1516 Wh battery and accepts up to 600W of solar input, compared to 1260 Wh and 400W for EcoFlow's model.

Battery expansion is available on the Yeti 1500X but not on the DELTA. The tradeoff is significant: the DELTA weighs just 30.9 lbs versus 45.6 lbs for the Yeti, and it offers 800 rated cycles to the Yeti's 500, giving it a clear edge in portability and long-term cell longevity.
