Common questions
- How long will the Goal Zero Yeti 500 run a box fan?
- About 5 hours from a full charge. A box fan averages about 85 W, and the 499 Wh battery gives about 424 Wh after inverter losses. That is 20% of the battery an hour.
- Can I run other things at the same time?
- Yes, up to about 415 W more of the 500 W output. Each thing you add shares the same battery, so the 5 hours for a box fan gets shorter.
