At a Glance
This comparison targets buyers weighing serious home-backup capacity against a lighter, more portable solar generator. The DELTA Pro 3 delivers 4,000W of running power and 4,096 Wh of stored energy, roughly doubling the Yeti 1500X on both counts. It also powered 48 out of 53 devices in our compatibility testing, compared to 43 for the Yeti.
With LFP chemistry rated for 4,000 cycles, the EcoFlow unit is built for years of regular use, while the Yeti's NMC cells are rated at 500 cycles. Solar input tells a similar story: the DELTA Pro 3 accepts up to 2,600W from panels versus 600W for the Yeti. The tradeoff is weight.
At 113.5 lbs, the DELTA Pro 3 is nearly 2.5 times heavier than the 45.6 lb Yeti 1500X, making the Goal Zero unit far easier to load into a vehicle or carry to a campsite.
