Works good for a generic charger .
Noticably louder than the factory shipped charger, but it works well.
This solved a huge problem with the other power supplies not being strong enough (including the one shipped with the laptop) to power the laptop and GPU during intense gaming/streaming events.
Gl502vs needs a 6mm plug and this is a 5.5mm .
I've had this product for 5 months and it just died on me.
I purchased this to have a back-up for my Asus GL502.
The charger died after a month of use.
If you want a charger for more than a year, don't buy this product.
