This Sector Power Charger for HP Compaq CQ60 CQ61 CQ71 DV4 DV5 DV6 DV7 [PC] is not the original brand but also works well and at a lower price .I use it on a HP DV7 2120sf and also another DV7 I no longer find the series. Charging time and stability in line like the HP charger original, I recommend it.
