Quick answer
EcoFlow and Goal Zero both sell 1kWh-class LiFePO4 power stations, but they’re built for different priorities. The EcoFlow Delta 2 is the value pick — about $500 cheaper and 8 lb lighter than the Goal Zero, with a roughly 50-minute wall recharge to 80% and an expansion path to 3,040Wh. The Goal Zero Yeti 1000 is the headroom pick — its 2,000W continuous inverter (3,600W surge) and ~900W max solar input target buyers who need to run bigger loads or recharge fast off a large panel array. Both back their 1kWh units with a full 5-year warranty applied automatically, so warranty length isn’t the deciding factor here the way it is in some other brand matchups.
EcoFlow built its name on fast-charging, app-connected power stations that made expandable home-backup setups mainstream, while Goal Zero built its name on rugged, expedition-tested gear aimed at output and reliability over raw specs on paper. Both now sell 1kWh-class LiFePO4 units, which makes them a natural head-to-head: the EcoFlow Delta 2 against the Goal Zero Yeti 1000.
Head to head
| Spec | EcoFlow Delta 2 | Goal Zero Yeti 1000 |
|---|---|---|
| Capacity | 1,024Wh LiFePO4 | 998Wh LiFePO4 |
| AC output | 1,800W (2,700W X-Boost) | 2,000W (3,600W surge) |
| Wall recharge to 80% | ~50 min | ~1.2 hr |
| Max solar input | ~500W | ~900W |
| Expandable | Yes, to 3,040Wh | No published expansion battery |
| Cycle life | 3,000-4,000 cycles | ~4,000 cycles |
| Weight | ~27 lb | ~35.3 lb |
| Warranty | 5 years (automatic) | 5 years (automatic) |
| Price | ~$699 | ~$1,199 |
Where EcoFlow wins
EcoFlow’s advantage is price, weight, and charge speed. The Delta 2 costs roughly $500 less than the Yeti 1000 while offering slightly more capacity (1,024Wh vs. 998Wh), and at about 27 lb it’s over 8 lb lighter to carry or load into a car. Per EcoFlow’s own specs, the Delta 2 also recharges to 80% in about 50 minutes on a wall outlet, close to half the Yeti’s 1.2-hour figure — useful if you need to top up fast between uses. And if your power needs grow, the Delta 2 has a clear expansion path to 3,040Wh with an add-on battery, something Goal Zero doesn’t currently offer for this model.
EcoFlow Delta 2
- About $500 cheaper than the Yeti 1000 with slightly more capacity.
- ~50-minute wall recharge to 80%, nearly twice as fast as the Yeti.
- Expandable to 3,040Wh — no comparable path on the Yeti 1000.

Where Goal Zero wins
Goal Zero’s advantage is raw output and solar headroom. According to Goal Zero’s published specs, the 6th-generation Yeti 1000 runs a 2,000W continuous inverter with a 3,600W surge rating, enough to handle power tools or space heaters that would trip the Delta 2’s 1,800W inverter (2,700W with X-Boost engaged). It also accepts up to 900W of combined solar input, nearly double the Delta 2’s ~500W ceiling, so it can recharge faster off a larger panel array during an extended outage or off-grid stay — a real advantage for buyers building around solar rather than wall power.
Goal Zero Yeti 1000
- 2,000W continuous / 3,600W surge — handles loads the Delta 2's inverter can't.
- Up to 900W of solar input, nearly double the Delta 2's ceiling.
- 5-year warranty applied automatically, same as the Delta 2 — no registration edge either way.
The verdict
Buy EcoFlow (Delta 2) if price, weight, and charge speed matter most — it’s also the top pick in our best portable power station roundup for a reason. Buy Goal Zero (Yeti 1000) if you need to run higher-draw tools or appliances and want to recharge fast off a large solar array. Both back their units with a full 5-year warranty applied automatically, so neither brand has an edge there — the right answer comes down to budget and how much continuous output or solar headroom you actually need.
