Goal Zero Yeti 1000X sizing guide

Same 983 Wh battery as the Yeti 1000 Core but a much bigger 1,500 W / 3,000 W surge inverter — clears loads the Core cannot. Here's exactly what it runs, how long, and which outages it covers — computed, not marketed.

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 1000X run?

With 1,500 W of continuous output and a 3,000 W surge rating, the Goal Zero Yeti 1000X runs refrigerator (modern), chest freezer, cpap machine (no humidifier), cpap with heated humidifier, oxygen concentrator, space heater (1500 w), and more. Its 983 Wh battery sets how long: a fridge for roughly a day, a CPAP for several nights.

How long will the Goal Zero Yeti 1000X run a refrigerator?

A modern refrigerator averages about 53 W (it cycles ~35% of the time), so the Goal Zero Yeti 1000X's 983 Wh runs one for roughly 17 h before recharging.
