Office depot has the Asus made ones, but its hard to catch them in stock. Now there are some good aftermarket ones on Amazon. I got one, can't remember what company right now, from China that's working great. It took like a month to get here tho. I had to borrow my mother-in-law's iPad, bleh! Anyway while I was waiting, I broke down & bought the office depot one. You have to be careful with the OG charger. It overheats, which is probably what caused ur short.
