Recharging with solar
The Goal Zero Yeti 500X accepts up to 120W of solar input. In real conditions that harvests about 450Wh on a sunny day (5 peak-sun hours).
Solar can keep up. A heated mattress pad uses about 432Wh a day at 8 hours of use, so with enough panels and good sun the Goal Zero Yeti 500X can run it indefinitely.
Tips
- Queen-size heated pads draw about 90W and cycle once warm.
- You’ll still have about 210W of AC capacity left for other devices at the same time, though they’ll share the same battery.
- The Goal Zero Yeti 500X uses NMC cells, which are lighter but rated for fewer cycles (typically 500–800) than newer LFP models.
