The numbers
| Battery capacity | 2048Wh (LFP) |
|---|---|
| Usable energy | 1884Wh (92% via 12V/USB DC output) |
| Continuous AC output | 2400W |
| Surge rating | 4800W |
| 12V car fridge running watts | 45W |
| Startup watts | 60W |
| Average draw | 18W |
| Estimated runtime | 4.4 days |
| Energy per day of typical use | 432Wh |
2048Wh × 0.92 = 1884Wh usable ÷ 18W average = 104.7 hours

Recharging with solar
The EcoFlow Delta 2 Max accepts up to 1000W of solar input. In real conditions that harvests about 3.8 kWh on a sunny day (5 peak-sun hours), or about 750Wh with one 200W panel.
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 EcoFlow Delta 2 Max 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 EcoFlow Delta 2 Max’s DC port instead of the AC outlet avoids inverter losses: about 143Wh more usable energy.
- The EcoFlow Delta 2 Max uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
