I have Dell Inspiron 5520. I have a problem with the power adapter and I want to buy new one.
I saw that my charger amperage is 3.34A (65W) but there are also adapters with 4.62A (90W) and 6.7A (130W)
Is it safe to use charger with other amperage? There are disadvantages with charger with bigger amperage?
Also, I saw that there are non Dell chargers that listed as compatible. Are they safe? (It's not the main question. Don't mark as duplicate. More edit: the link is even not similiar this question). I talk about charger that the technical specs are identical, only it's not OEM charger.
