Methodology

PowerStation Match uses fixed estimates so the math is easy to inspect and compare across brands.

• AC loads: usable Wh = rated Wh x 0.85.
• Runtime hours = usable Wh / device watts.
• CPAP nights = runtime hours / 8.
• Compatible CPAP DC converter cable mode uses rated Wh x 0.92, because it avoids the AC inverter conversion step.

The station and device JSON files include source URLs and checked dates. Current production data refresh is blocked until live extraction and verification credentials are connected.

A CPAP is a medical device. These are runtime estimates, not medical advice or a medical-safety guarantee. Test your exact setup at home before relying on it.
