What will the Goal Zero Yeti 500 run?

The Goal Zero Yeti 500 stores 499Wh with 500W of output (1,000W surge). Running one thing at a time, that's about 4 to 8.5 hours of a refrigerator if it can start one (see below), about 13 to 27 hours of a CPAP with the humidifier off and about 14 to 19 hours of Wi-Fi.

499Wh and 500W at 16.1 lb: a step up from the Yeti 300 for an overnight CPAP or a router and lights, but not a fridge.

Runtime: 499Wh × 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 500 run a refrigerator?

Not reliably: may not start it (surge 1,000W). If it does run one, it lasts about 4 to 8.5 hours.

How long will the Goal Zero Yeti 500 run a CPAP?

About 13 to 27 hours with the humidifier and heated tube off, or about 5 to 12 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 500 run a space heater?

Only briefly: a space heater on high draws up to about 1,500 watts, so it lasts about 0.5 hours. See how to stay warm without power for what works better.
