  "description": "Portable power stations fit for CPAP backup, filtered on minimum capacity, waveform safety, and bedside-practical weight, then ranked on documented pure sine output, capacity, and portability.",

    "disqualifierRules": [
      "Battery capacity below 240 Wh — obviously too small for meaningful overnight use",

    "rankingExplanation": "Eligible products are scored as: documented pure sine wave (+80), capacity ×0.15 (capped at 1,100 Wh — beyond that adds little for CPAP), lightness (15 kg − weight) ×8, documented switchover (+30). No runtime hours are computed or claimed.",
