Quick check: make sure the wattage matches

This charger supplies 65W over USB-C. 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: Use a 65W USB-C PD charger; ThinkPad E15 Gen 4 charges over USB-C.

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.
  • ✓
    USB-C PD requires sufficient wattage AND a rated cable
    A non-PD USB-C charger, or a PD charger with a thin cable, will under-deliver. XPS 15/17 specifically need a 5A e-marked cable for 130W.
  • ✓
    A USB-C data port is not always a charging port
    Confirm 'USB-C Power Delivery' or 'charging' is listed for the port before recommending a USB-C charger.
