The numbers
| Battery capacity | 512Wh (LFP) |
|---|---|
| Usable energy | 435Wh (85% via AC outlets) |
| Continuous AC output | 500W |
| Surge rating | 750W |
| Window AC (5,000 BTU) running watts | 450W |
| Startup watts | 1300W |
| Average draw | 315W |
| Estimated runtime | 1.4 hours |
| Energy per day of typical use | 2.5 kWh |
512Wh × 0.85 = 435Wh usable ÷ 315W average = 1.4 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 window AC (5,000 BTU) uses about 2.5 kWh a day at 8 hours of use, more than the Anker 535 PowerHouse’s best-case solar harvest. Solar will stretch the runtime but not sustain it.
Tips
- Small window units draw around 450W while the compressor runs. On hot days it rarely switches off, so expect 60–80% duty.
- The Anker 535 PowerHouse uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
