Since my original power supply has passed after heavy use, I searched on Amazon for an alternative. Because of the reviews it was the Leike and I must say it is a top device. The packaging is good solved. The device is small and handy and fits exactly. The most interesting thing that was there was almost no heat generation, even after 10 hours - Top.
I hope I need with other laptops when not a new, but if it does it will be a Leike.
