Up for sale is a genuine Lenovo M700 Tiny power supply. This is a used item, but it comes from a working machine. It is in good working order. There are no rips or tears of the protective outer rubber layer of the cord.
The power supply puts out 20 Volts at 3.25 Amps equalling 65 Watts.
I do not know if this is compatible with other models, but I assume that it is so. Please check for compatibility with your machine before purchasing.
