Who should not buy the Goal Zero Yeti 1000?
Skip the Goal Zero Yeti 1000 if any of these describe you; each comes from its published specs.
- You carry it often. At 35.3 lb, it is heavier than 4 of the 6 500–999 Wh models that publish a weight. The EcoFlow RIVER 2 Pro holds 768 Wh at 18.2 lb.
- You may want more battery later. The Goal Zero Yeti 1000 isn't listed as expandable. The EcoFlow DELTA 3 Plus (1,024 Wh) accepts extra batteries.
How long does the Goal Zero Yeti 1000 last at different loads?
About 849 Wh reaches the AC outlets, so a steady 100 W load runs for about 8.5 h and a load at its full 2,000 W rating for about 25 minutes.
| Steady AC load | Runtime from full |
|---|---|
| 25 W | 34 h |
| 50 W | 17 h |
| 100 W | 8.5 h |
| 200 W | 4.2 h |

What does the Goal Zero Yeti 1000 cost per kWh over its rated life?
About $0.30 per kWh of storage at list price, if you use all 4,000 rated cycles. The median for 500–999 Wh models is $0.25 per kWh, so the Goal Zero Yeti 1000 is more expensive over its rated life.
Rated life energy = 998 Wh × 4,000 cycles ≈ 3,994 kWh. List price $1,199.95 ÷ 3,994 kWh ≈ $0.30.
How many hours of sun does the Goal Zero Yeti 1000 need to refill?
With panels delivering 75% of their rating (our calculator's default), the Goal Zero Yeti 1000 needs the hours of strong sun below. Its 900 W solar limit caps the charge rate, so panels beyond about 1,200 W add nothing in strong sun.
| Panels | Charge rate | Sun hours to refill |
|---|---|---|
| 100 W of panels | 75 W | 13.3 h |
| 200 W of panels | 150 W | 6.7 h |
| 400 W of panels | 300 W | 3.3 h |
| 800 W of panels | 600 W | 1.7 h |
