Bought this to put in my "to-go" bag so I wouldn't have to unplug the original kit from wall each time I traveled away from home. Paid a bit more but, bas a bit leery to buy a 3rd-party as I didn't want to somehow potentially damage my new laptop.
Works as intended. No issues at all and wrapping the cable is very easy. Taken it already on business trips without taking up too much space in luggage.
