mguerra79 Thiscable allows power to pass and charge devices. If the keyboard has power output, yes. I connect my cable to the USB3 port and charge my mobile all the time there. Not in the keyboard, because it is a laptop, but it charges... If you mean to substitute original keyboard cable, you need to make sure that it has a type C port. The small one with round corners (see the pictures).

mguerra79 [EDIT]: Mine already came. I confirm that it has a sharpener in the top tip, and you can check my comment with photos. [END EDIT]I'm not sure, because I haven't bought it yet, but in the old days, this kind of pencil has the sharpener in th back tip, the one you tip off to load extra lead, inside you can sharpen the lead tip with it. Usually is some sort of cross, with a hole in the middle, where the tip fits, and you rotate it to sharpen...
