How to match charger with laptop

[phoenixfeatinc]

During a trip, my family and I accidentally mixed up the 2 chargers among our 2 laptops - 1 an old HP Pavilion purchased 2017 and 1 more recent HP Elitebook.  Both chargers are blue tipped 45W, but it is unclear which ones go with which.  What is the best way to figure this out?  I looked on packing lists from the original shipments, but the chargers' serial #'s were not itemized out.

Please turn both chargers up-side-down to get their part #  (p/n) we van work out which is which. The Pavilion must use much higher watt charger, can't be 45W

Thank you for your help!  Attached are the photos of the two chargers.  One looks newer than the other, but they both say 45W (in different locations).

I can't read their labels, but those labels should have p/n on them. Since they both have 45W, part number for the Pavilion is 741553-850  or 741553-852 (for use only in Argentina).
