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 1500X run?

With 2,000 W of continuous output and a 3,500 W surge rating, the Goal Zero Yeti 1500X runs refrigerator (modern), chest freezer, cpap machine (no humidifier), cpap with heated humidifier, oxygen concentrator, space heater (1500 w), and more. Its 1,516 Wh battery sets how long: a fridge for roughly a day, a CPAP for several nights.

How long will the Goal Zero Yeti 1500X run a refrigerator?

A modern refrigerator averages about 53 W (it cycles ~35% of the time), so the Goal Zero Yeti 1500X's 1,516 Wh runs one for roughly 26 h before recharging.
