I have an ASUS zenbook UX303UA model that I bought almost 7 years ago for uni and it still works relatively well. However, the original charger broke due to age. I use a third-party charger I bought from Amazon because I could not find where to purchase the original charger from (even in the asus website). What's very frustrating with the 3rd party chargers is that its very loose and I have to consistently re-adjust it every time just so it can charge my laptop. Does anyone know where I can purchase an original model of the charger? Your advice/help will be greatly appreciated!
