The numbers
| Battery capacity | 2048Wh (LFP) |
|---|---|
| Usable energy | 1884Wh (92% via 12V/USB DC output) |
| Continuous AC output | 2400W |
| Surge rating | 4800W |
| Wi-Fi router and modem running watts | 20W |
| Startup watts | 20W |
| Average draw | 20W |
| Estimated runtime | 3.9 days |
| Energy per day of typical use | 480Wh |
2048Wh × 0.92 = 1884Wh usable ÷ 20W average = 94.2 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 Wi-Fi router and modem uses about 480Wh a day at 24 hours of use, so with enough panels and good sun the EcoFlow Delta 2 Max can run it indefinitely.
Tips
- Keeping internet up during an outage costs very little power, as long as your ISP's equipment down the street still has power too.
- 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.
