What will the Goal Zero Yeti 1000 run?
The Goal Zero Yeti 1000 stores 998Wh with 2,000W of output (3,600W surge). Running one thing at a time, that's about 8 to 17 hours of a refrigerator, about 25 to 55 hours of a CPAP with the humidifier off and about 27 to 38 hours of Wi-Fi.
998Wh and 2,000W (3,600W surge) by Goal Zero's spec table, but 35.3 lb, about 10 lb more than the lightest 1kWh rivals.

Runtime: 998Wh × 90% usable × 85% inverter efficiency ÷ (the average draw + about 10W the station uses itself), from Energy Star figures and makers' manuals. "Runs it?" checks its output and surge rating against the cautious running and starting figures on generator makers' and DTE Energy's charts. Plan on the low end.

Questions
Can the Goal Zero Yeti 1000 run a refrigerator?
Yes. It runs one for about 8 to 17 hours on its own, and its output and surge rating cover the cautious figures on generator makers' charts.
How long will the Goal Zero Yeti 1000 run a CPAP?
About 25 to 55 hours with the humidifier and heated tube off, or about 10 to 25 hours with them on, running nothing else. Running it from the 12V outlet through the CPAP maker's own converter avoids the inverter's losses, so it lasts longer than these figures.
Can the Goal Zero Yeti 1000 run a space heater?
Only briefly: a space heater on high draws up to about 1,500 watts, so it lasts about 0.5 to 1.5 hours. See how to stay warm without power for what works better.
