The numbers
| Battery capacity | 518Wh (NMC) |
|---|---|
| Usable energy | 440Wh (85% via AC outlets) |
| Continuous AC output | 500W |
| Surge rating | 1000W |
| Box fan running watts | 75W |
| Startup watts | 100W |
| Average draw | 75W |
| Estimated runtime | 5.9 hours |
| Energy per day of typical use | 600Wh |
518Wh × 0.85 = 440Wh usable ÷ 75W average = 5.9 hours

Recharging with solar
The Jackery Explorer 500 accepts up to 100W of solar input. In real conditions that harvests about 375Wh on a sunny day (5 peak-sun hours).
Solar can’t fully keep up. A box fan uses about 600Wh a day at 8 hours of use, more than the Jackery Explorer 500’s best-case solar harvest. Solar will stretch the runtime but not sustain it.
Tips
- A 20-inch box fan draws 50–100W depending on speed.
- You’ll still have about 425W of AC capacity left for other devices at the same time, though they’ll share the same battery.
- The Jackery Explorer 500 uses NMC cells, which are lighter but rated for fewer cycles (typically 500–800) than newer LFP models.
