This was the 3rd power supply I bought from Revain to try to get the full power out of my K17A. Any other power supply was able to power the unit, but my laptop would not charge. Luckily I found this one that even calls the K17A by its name in the listing title. Works perfectly. Not only is the docking station fully charged, it has enough power to charge my laptop. Exactly what I needed!
