The numbers
| Battery capacity | 512Wh (LFP) |
|---|---|
| Usable energy | 471Wh (92% via 12V/USB DC output) |
| Continuous AC output | 500W |
| Surge rating | 750W |
| 12V car fridge running watts | 45W |
| Startup watts | 60W |
| Average draw | 18W |
| Estimated runtime | 26 hours |
| Energy per day of typical use | 432Wh |
512Wh × 0.92 = 471Wh usable ÷ 18W average = 26.2 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 keep up. A 12V car fridge uses about 432Wh a day at 24 hours of use, so with enough panels and good sun the Anker 535 PowerHouse can run it indefinitely.
Tips
- Compressor coolers like Dometic, ICECO and BougeRV plug into the 12V car port, which skips inverter losses entirely.
- 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.
