Higher-wattage compatibility
A Lenovo round-tip barrel charger at 65W safely powers any Lenovo round-tip barrel laptop rated 65W 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.
Connector
This charger uses the Lenovo round-tip barrel (4.0mm x 1.7mm round tip), a Lenovo connector. Match the connector exactly — it is not interchangeable with other tips.
