Dell Inspiron 15R Power Adapter Charger

My old adapter was still powering my computer but nothing else. This power supply is a 90W supply and the system BIOS on my Dell Inspiron 15R recognizes it & it charges correctly. Please don't be fooled into buying the cheaper versions from other vendors. I have had an experience with cheaper power supplies that burn themselves out after a year, to the day!. This is especially true if you are using USB devices that need to draw power from the laptop via the USB port. I know this from personal experience.
This supply is an real OEM replacement for my original laptop power supply, not just a cheaper knockoff.
