The numbers
| Battery capacity | 3600Wh (LFP) |
|---|---|
| Usable energy | 3312Wh (92% via 12V/USB DC output) |
| Continuous AC output | 3600W |
| Surge rating | 7200W |
| Wi-Fi router and modem running watts | 20W |
| Startup watts | 20W |
| Average draw | 20W |
| Estimated runtime | 6.9 days |
| Energy per day of typical use | 480Wh |
3600Wh × 0.92 = 3312Wh usable ÷ 20W average = 165.6 hours

Recharging with solar
The EcoFlow Delta Pro accepts up to 1600W of solar input. In real conditions that harvests about 6 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 Pro 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 Pro’s DC port instead of the AC outlet avoids inverter losses: about 252Wh more usable energy.
- The EcoFlow Delta Pro uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.

FAQ
Will the EcoFlow Delta Pro run a Wi-Fi router and modem overnight?
Yes. Eight hours uses about 160Wh, roughly 5% of the EcoFlow Delta Pro’s usable capacity.
How long does the EcoFlow Delta Pro take to recharge with solar?
With its maximum 1600W of solar input it refills in about 3 hours of strong sun. With a single 200W panel, expect about 4.8 sunny days (24 hours of full sun).
