The numbers
| Battery capacity | 512Wh (LFP) |
|---|---|
| Usable energy | 471Wh (92% via 12V/USB DC output) |
| Continuous AC output | 500W |
| Surge rating | 750W |
| Wi-Fi router and modem running watts | 20W |
| Startup watts | 20W |
| Average draw | 20W |
| Estimated runtime | 24 hours |
| Energy per day of typical use | 480Wh |
512Wh × 0.92 = 471Wh usable ÷ 20W average = 23.6 hours

Recharging with solar
The Anker 535 PowerHouse accepts up to 120W of solar input. In real conditions that harvests about 450Wh on a sunny day (5 peak-sun hours).
Solar can’t fully keep up. A Wi-Fi router and modem uses about 480Wh a day at 24 hours of use, more than the Anker 535 PowerHouse’s best-case solar harvest. Solar will stretch the runtime but not sustain it.
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 535 PowerHouse’s DC port instead of the AC outlet avoids inverter losses: about 36Wh more usable energy.
- The Anker 535 PowerHouse uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
