I've had to change my Surface Pro 4 charger a few times and have always bought the $70 charger from Microsoft itself. Maybe I'm lucky, but any charger would be finicky and would only work with certain sockets and in the right position (every pin is the same size, so it's hard to tell which way it's preferred, and 99% of the time I dialed poorly and had to switch off and flip to get the necessary electric current). This charger doesn't give me the same contact problems, is a much cheaper alternative, comes in a great carrying case and charges just as fast as the Microsoft charger. Would highly recommend and will now consider other KINGDO products in the future.
