Higher-wattage compatibility
A Lenovo slim-tip charger at 300W safely powers any Lenovo slim-tip laptop rated 300W or below. A charger rated HIGHER than the original wattage is safe, provided connector type, polarity and (for barrel) tip size and voltage all match. The laptop draws only the current it needs.
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.
