How Long Will the EcoFlow Delta 3 Max Run a Chest Freezer?

Updated 2026-10-17 · Yes

About 2.1 days. The EcoFlow Delta 3 Max stores 2048Wh, and a chest freezer averages about 35W because it cycles on roughly 35% of the time. That’s about 2.1 days of round-the-clock use.

Recharging with solar

The EcoFlow Delta 3 Max accepts up to 500W of solar input. In real conditions that harvests about 1.9 kWh on a sunny day (5 peak-sun hours), or about 750Wh with one 200W panel.

Solar can keep up. A chest freezer uses about 840Wh a day at 24 hours of use, so with enough panels and good sun the EcoFlow Delta 3 Max can run it indefinitely.

Tips

  • Chest freezers are well insulated, so their compressor runs less than an upright fridge's. Keep the lid closed during an outage.
  • You’ll still have about 2300W of AC capacity left for other devices at the same time, though they’ll share the same battery.
  • The EcoFlow Delta 3 Max uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
