Is it ok to use a different brand of charger on a laptop(my laptop is an acer al15-51m-55r1 and the charger I might buy is an HP) I've checked every tech store in my area and they don't have an acer charger that fits my laptop (4.8 × 1.7 mm barrels type) and the only thing that fits is an HP charger, the employee said its a 19v and matchs exactly my charger pin size and the only difference is the Watts its high than my previous charger. should I buy it?
