Are all the hp pavilion ze chargers the same?
I believe so. However, there are different “power” outages even for the same charger, meaning some HP chargers are 90W whereas others are only 60W. If you look at Topmic’s website, they sell HP Pavilion ZE series laptop charger, so I think they are all the same http://www.topmic.com/hp-pavilion-ze-lap… In order to be sure the charger will work with your laptop, 1. Make sure the voltage output match your original charger 2. Make sure the amp output is at least >= your charger. Best of luck.
