Replacement ASUS X55CR Laptop AC Adapter 19V Charger High quality 65W & 90W power supply, elbow 90-degree DC connector with diameter of 5.5*2.5mm, 19V 4.74A 90W fully compatible with 19V 3.42A 65W works with ASUS notebook PCs.
charger power is excellent, lasts 6-7 hours between charges. However, I regret buying the higher power charger because -- since the charger protrudes out the bottom and back -- it forces me to use the computer when it is in a tilted position, affecting my view of the screen. Trouble is, this mini laptop's keyboard is on the small side and there's no way I intend to use it for 6-7 hours at a time. Very good charger, bad call by me -- even though I contacted your customer service dept before ordering.
