I bought this is as a backup to leave in my suitcase so I wouldn't have to unplug the unit at home.
Seems to work fine for the couple of times I've used it.
I had a hard time finding a second power cord for my Asus Laptop UX303UA.
Lasted less than 6 months.
Get different brand.
Started having problems with it after a few months.
Save yourself the hassle and buy a different charger.
