Well at least for my np8130. My 2nd charger died out of nowhere and I have urgent work to do. I search online for a replacement and the only company that sells something with at least an expedited shipping service is Discountbatt. I just checked my tracking and its expected to arrive 6 days after I made the order! Why are there such few options? I read in other threads to refer to your previous vendor but powernotebooks.com went out of business and will even one of these vendors ship it any faster than expedited shipping? Also I am getting a 120w charger when there was an option for 90w. I hope I got the right one but I also read I might need a 180w charger. Really??? Sorry but I'm really frustrated right now. I appreciate any info.
