The numbers
| Battery capacity | 512Wh (LFP) |
|---|---|
| Usable energy | 435Wh (85% via AC outlets) |
| Continuous AC output | 500W |
| Surge rating | 750W |
| Chest freezer running watts | 100W |
| Startup watts | 700W |
| Average draw | 35W |
| Estimated runtime | 12 hours |
| Energy per day of typical use | 840Wh |
512Wh × 0.85 = 435Wh usable ÷ 35W average = 12.4 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 chest freezer uses about 840Wh 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
- Chest freezers are well insulated, so their compressor runs less than an upright fridge's. Keep the lid closed during an outage.
- You’ll still have about 400W of AC capacity left for other devices at the same time, though they’ll share the same battery.
- The Anker 535 PowerHouse uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
