I know there is an issue with charging a nexus 10 by a micro-usb cable since a battery is drained out faster than charging. Thus it has a pogo charging connect and supposed to be charged by a magnetic pogo cable. However, unfortunately the cable didn't come with Nexus 10 for some reason, and there have been no place to purchase it separately though. Here it is!!! it makes nexus 10 charged 40% faster than a usb cable. It will be available for sale on Amazon and ebay soon! I will provide you a link to buy it later.
