laptop charger(s), mac OR hp

i bought the ad/dc adapters sept 29, '20 to work on a friends' laptops, who didnt need them when i was done about a week later, only used for that long and worked fine. the other i've never used but am unclear if it was new or not, so selling as used & untested. the car adapter and the hp adapter have the same plug, so i believe they fit the same laptops. i dont recall but the listing i got it from listed HP ProBook 4510S 4520S 4530S 4540S. i had bought the apple charger for a 13" macbook pro i believe. i keep odd hours but try to answer question w/in 24 hours as well as try to ship same day. however, due to current life, i am unsure of PO Pick-ups, so list as 2 day ship.
