Goal Zero Yeti 700 sizing guide
Goal Zero’s LiFePO4 value unit — a 1,000 W inverter for fridge and essentials. Here's exactly what it runs, how long, and which outages it covers — computed, not marketed.
~2.3 h AC; up to 200 W solar · 21 lb · 2× AC, USB-A/C, car.
What the Yeti 700 runs — and for how long
| Appliance | Running | Runs it? | Approx. runtime |
|---|---|---|---|
| Refrigerator (modern) | 150 W (1,200 W surge) | yes | ~12 h |
| Chest Freezer | 100 W (1,000 W surge) | yes | ~17 h |
| CPAP Machine (no humidifier) | 40 W | yes | ~15 h |
| CPAP with Heated Humidifier | 60 W (95 W surge) | yes | ~13 h |
| Oxygen Concentrator | 350 W (600 W surge) | yes | ~1.7 h |
| Space Heater (1500 W) | 1,500 W | too much | — |
| Window AC (8,000 BTU) | 715 W (1,250 W surge) | yes | ~1.2 h |
| Window AC (12,000 BTU) | 1,100 W (1,800 W surge) | too much | — |
| Gas Furnace Blower (1/2 HP) | 800 W (2,350 W surge) | too much | — |
| Microwave (1000 W cooking) | 1,200 W | too much | — |
| Sump Pump (1/3 HP) | 800 W (1,500 W surge) | yes | ~3.8 h |
| Sump Pump (1/2 HP) | 1,050 W (2,150 W surge) | too much | — |
| Well Pump (1/2 HP) | 1,000 W (2,100 W surge) | too much | — |
Runtime uses each load's duty-weighted average draw against 90% of the rated capacity — conservative on purpose. Cyclic loads (fridges, pumps) run far longer than running-watts × capacity would suggest.

Common questions
What can the Goal Zero Yeti 700 run?
With 1,000 W of continuous output and a 1,500 W surge rating, the Goal Zero Yeti 700 runs refrigerator (modern), chest freezer, cpap machine (no humidifier), cpap with heated humidifier, oxygen concentrator, window ac (8,000 btu), and more. Its 677 Wh battery sets how long: a fridge for roughly a day, a CPAP for several nights.
How long will the Goal Zero Yeti 700 run a refrigerator?
A modern refrigerator averages about 53 W (it cycles ~35% of the time), so the Goal Zero Yeti 700's 677 Wh runs one for roughly 12 h before recharging.
