Can a Goal Zero Yeti 300 run a space heater (1500 w)?

Q: Can the Goal Zero Yeti 300 run a space heater (1500 w)?

No. A space heater (1500 w) needs 1,500 W continuous and a 1,500 W startup surge, but the Goal Zero Yeti 300 only delivers 350 W continuous and a 600 W surge — so it can’t sustain the running load. You'd want a larger unit.

No — the Goal Zero Yeti 300 can't run a space heater (1500 w).
The space heater (1500 w) draws about 1,500 W (a steady resistive load); the Yeti 300 delivers 350 W continuous and 600 W surge. That's not enough continuous output.
