Replacement power cable for ASUS Q302L

Hello,

I recently purchased laptop model ASUS Q302L.  Unfortunately, it underwent a bit of stress when I dropped it and tried to grab the power cord, which instead caused the connection part to tear.  I've never seen anything like this.  Luckily I was able to remove the cord from the charging port but the charger is now worthless.  I am also lucky to be on full battery at the moment but that will not last long.  Are there any recommendations as to where and what type of replacement cord to purchase?  I have searched eBay and Amazon but I am unsure if those will suffice.  I did not buy the extended warranty and the store is telling me this is neglect and will not replace.  Any suggestions on a reputable store/replacement cord is appreciated. 

Thank you.
