How Long Will the Goal Zero Yeti 500X Run a 12V Car Fridge?
Updated 2026-10-17 · Yes
About 26 hours. The Goal Zero Yeti 500X stores 505Wh, and a 12V car fridge averages about 18W because it cycles on roughly 40% of the time. That’s about 1 day of round-the-clock use.
The numbers
| Battery capacity | 505Wh (NMC) |
|---|---|
| Usable energy | 465Wh (92% via 12V/USB DC output) |
| Continuous AC output | 300W |
| Surge rating | 600W |
| 12V car fridge running watts | 45W |
| Startup watts | 60W |
| Average draw | 18W |
| Estimated runtime | 26 hours |
| Energy per day of typical use | 432Wh |
505Wh × 0.92 = 465Wh usable ÷ 18W average = 25.8 hours

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 12V car fridge uses about 432Wh a day at 24 hours of use, so with enough panels and good sun the Goal Zero Yeti 500X can run it indefinitely.
Tips
- Compressor coolers like Dometic, ICECO and BougeRV plug into the 12V car port, which skips inverter losses entirely.
- Running it from the Goal Zero Yeti 500X’s DC port instead of the AC outlet avoids inverter losses: about 35Wh more usable energy.
- The Goal Zero Yeti 500X uses NMC cells, which are lighter but rated for fewer cycles (typically 500–800) than newer LFP models.
