I just got my new Vaio F series today, and I was thinking of getting a universal adaptor for when I need to carry my laptop with me (e.g. Class and stuff) and then leave the Original charger at home and ready for use when I get home.
The one I have been looking at is the Cooler Master USNA 120 http://www.coolermaster.com/product.php?product_id=6739
It’s pretty small and light compared to the one that comes with the Vaio, so it would be great for traveling.
The power adaptor that comes with my Vaio has an output of 19,5V - 7,7 A
Where the one from Cooler Master is 18 - 20Vdc / 19Vdc 5.79A and provides 120 Watt
My question is, if it provides enough power, to keep the Vaio running and charge the battery at the same time?
Or will it not charge the battery but at least keep it from draining?
Or what will happen?
Hope someone can answer my question and thanks in advance.
