Goal Zero Yeti 6000X sizing guide
Goal Zero’s largest single-unit battery — over 6 kWh for multi-day whole-essentials backup, though the inverter is a modest 2,000 W. Here's exactly what it runs, how long, and which outages it covers — computed, not marketed.
Up to 600 W solar input · 114 lb · 2× 120V AC, USB-A/C.
What the Yeti 6000X runs — and for how long
| Appliance | Running | Runs it? | Approx. runtime |
|---|---|---|---|
| Refrigerator (modern) | 150 W (1,200 W surge) | yes | ~104 h |
| Chest Freezer | 100 W (1,000 W surge) | yes | ~156 h |
| CPAP Machine (no humidifier) | 40 W | yes | ~137 h |
| CPAP with Heated Humidifier | 60 W (95 W surge) | yes | ~114 h |
| Oxygen Concentrator | 350 W (600 W surge) | yes | ~16 h |
| Space Heater (1500 W) | 1,500 W | yes | ~3.6 h |
| Window AC (8,000 BTU) | 715 W (1,250 W surge) | yes | ~11 h |
| Window AC (12,000 BTU) | 1,100 W (1,800 W surge) | yes | ~7.1 h |
| Gas Furnace Blower (1/2 HP) | 800 W (2,350 W surge) | yes | ~14 h |
| Microwave (1000 W cooking) | 1,200 W | yes | ~4.6 h |
| Sump Pump (1/3 HP) | 800 W (1,500 W surge) | yes | ~34 h |
| Sump Pump (1/2 HP) | 1,050 W (2,150 W surge) | yes | ~26 h |
| Well Pump (1/2 HP) | 1,000 W (2,100 W surge) | yes | ~36 h |
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 6000X run?
With 2,000 W of continuous output and a 3,500 W surge rating, the Goal Zero Yeti 6000X runs refrigerator (modern), chest freezer, cpap machine (no humidifier), cpap with heated humidifier, oxygen concentrator, space heater (1500 w), and more. Its 6,071 Wh battery sets how long: a fridge for roughly a day, a CPAP for several nights.
How long will the Goal Zero Yeti 6000X run a refrigerator?
A modern refrigerator averages about 53 W (it cycles ~35% of the time), so the Goal Zero Yeti 6000X's 6,071 Wh runs one for roughly 104 h before recharging.
