| Battery capacity | 768Wh (LFP) |
|---|---|
| Usable energy | 707Wh (92% via 12V/USB DC output) |
| Continuous AC output | 1200W |
| Surge rating | 1600W |
| Wi-Fi router and modem running watts | 20W |
| Startup watts | 20W |
| Average draw | 20W |
| Estimated runtime | 35 hours |
| Energy per day of typical use | 480Wh |
768Wh × 0.92 = 707Wh usable ÷ 20W average = 35.3 hours

Recharging with solar
The Anker SOLIX C800 Plus accepts up to 300W of solar input. In real conditions that harvests about 1.1 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 Anker SOLIX C800 Plus 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 Anker SOLIX C800 Plus’s DC port instead of the AC outlet avoids inverter losses: about 54Wh more usable energy.
- The Anker SOLIX C800 Plus uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
