Not for laptops needing other voltages

Buyers whose original charger specifies a different output voltage, current rating or tip diameter cannot use this adapter. It also does not suit devices that require a higher wattage supply or a proprietary connector other than 4.0×1.35 mm.

Connector size 4.0×1.35 mm decides fit

Match the barrel dimensions on your original adapter exactly; a mismatch means the plug will not seat or charge reliably. Verify the 4.0 mm outer diameter and 1.35 mm inner pin before ordering.
