Query: Kindle Charging time-saver!

We've got 6 Kindles that need to be charged almost every night after a class of students use them to view resource material. We plug in all 6 at once, DONE! I was pleasantly surprised by the length and heavy gauge thickness of the cord. Colors are vibrant and seems to be pretty scratch resistant. Nicely done.
