I have an HP Laptop. I also have a (school) HP Chromebook. I bring my laptop to school, and I don't use the Chromebook charger. I was thinking to bring the Chromebook charger to school to be able to keep the OEM charger at home, but the output amperage was different. My laptop accepts input as "19.5V, 3.33A", while my Chromebook charger reads "19.5V, 2.31V". I assume that since the amperage is lower, it is compatible, can someone please clarify? Thanks!
