EcoFlow DELTA 3 Plus vs Goal Zero Yeti 700
Side-by-side on the specs that decide it — surge, capacity, runtime and price.
Both models' specs verified against manufacturer listings · Last updated
The short answer
EcoFlow DELTA 3 Plus costs $50 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 3 Plus holds 51% more energy (1024Wh vs 677Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 Plus has 2600W more surge headroom (3600W vs 1000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 700 is 8.4 lb lighter (20.3 lb vs 28.7 lb).
We'd skip the Goal Zero Yeti 700 in this matchup. It costs $50 more than the EcoFlow DELTA 3 Plus while matching or trailing it on capacity, surge and cycle life — there's no spec here that justifies the premium.
The DELTA 3 with a $100 premium for smart-home integration and faster UPS switching. Same battery, same surge.
Best for: Home-office setups where a desktop or NAS can't tolerate a power blip.
Where it falls short:
- $100 more for features many buyers never use
- Same 1024Wh as the cheaper DELTA 3
The largest of the rugged compacts. Still not an appliance unit — 600W of output caps what it can drive — but a durable mid-size companion.
Best for: Rugged off-grid use where durability outranks running heavy loads.
Where it falls short:
- 600W output rules out compressors and heaters
- 20.3 lb is heavy for 677Wh
