Quick check: make sure the wattage matches

This charger supplies 135W over Barrel (HP Smart Pin). To find what your laptop needs, read the OUTPUT line on your current charger — the volts × amps is the wattage (e.g. 20V × 3.25A = 65W) — or check the label on the underside of your laptop. The same connector at an equal-or-higher wattage is safe.

Note: 15-inch Spectre uses a 135W 4.5mm barrel charger, not USB-C - do not buy a 65W USB-C charger for this model.

Why this charger is safe

  • ✓
    Higher wattage is generally safe
    Example: a 90W HP Smart adapter safely powers a 65W HP laptop. A 65W USB-C PD charger safely powers a 45W USB-C laptop.
  • ✓
    Lower wattage is not safe for full performance
    Most relevant for XPS 15/17 (130W) and Spectre x360 15/16 (135W) where a 65W charger is insufficient.
  • ✓
    Barrel tip size must match exactly
    A 7.4mm plug will not fit a 4.5mm jack and vice-versa. Dell and HP barrel tips are NOT interchangeable even at the same diameter (different pin/signalling).
  • ✓
    HP Smart Pin and Dell barrels are brand-specific
    HP Smart adapters carry a centre 'sense' pin used for wattage negotiation; Dell uses its own 1-wire ID. Mismatched brand can cause 'AC adapter not recognised' and refusal to fast-charge.
