DO NOT BUY. I bought a MacBook adapter, which worked for 6 months before it broke. It overheats super quickly too everytime I used it. Sometimes there's also a spark when I take it off my laptop. When I opened the charger, the parts does not look genuine at all. It claims to have a 1 year warranty but when I contacted them they said to send the charger back to them in CHINA and if I do not have time to do that then they offered me a free delivery charge if I order a new one. The level of stupidity goes beyond my understanding. Stay off this $#*!ty company.
