Alternate laptop Power Supply

My laptop requires 18.5 volt, 2.7 amp
the P?\S was lost and I have an alternate that apprears to power up the laptop so I know the connector and polarity is right. Its 18.5 volt 4.9 amp. I’ve been told that as long as the amp is higher than the laptop requires, I will not damage the H/W using it. Do you agree??
