19.5v 6.15a adapter for 20v 4.5a laptop

[Dopeyd]

Hello there,

I have a new lenovo laptop with a 20v 4.5a adapter. My old lenovo laptop had a 19.5v 6.15a adapter. Is the old adapter compatible with my new laptop?

Hi 06yfz450ridr,

Thank you for your reply! But I was wondering if the diffirence in voltage and amperage may wreck my new laptop.
