https://www.amazon.com/Genuine-Dell-Replacement-Adapter-Compatible/dp/B00I8V9KYK is a non-DELL but your choice on that.
Hi there. I recently bought a new laptop, and I'm having a much harder time finding a compatible replacement charger online than I have for any previous laptop. Simply googling the name hasn't turned up anything with a matching wattage, so I'm having to get technical about this. My question is, if I purchase a charger with the same model # that's printed on the back of mine, does it guarantee a fit? I think I found another with matching specs, but I'm not sure how to find the size of the part that plugs into the laptop by looking at the brick.
Thanks for any and all help.
