HP Pavilion dv7-6b57nr Charger
This is a great company for your computer power needs. They have great prices on chargers and batteries for many older model computers. I was able to buy a new charger for my 2010 HP laptop for cheap. The charger itself is of high quality and matches my factory charger precisely. I will definitely get a new battery for my laptop from Next Day Power soon as well. Another helpful tool this company provides is they provide a chart of the watts and amps of each charger on the webpage, and if it is safe to use with your computer. They shipped it out quick and it was at my doorstep in a reasonable amount of time. I highly recommend!
