The dock went on sale at the official ASUS online store for £24.99 earlier this month, following its official launch at the CES expo.
The manufacturer has confirmed to Pocket-Lint that all current supplies have already been extinguised, but promised more are on the way.
An ASUS representative said: "It's sold out already, but more stock should be landing shortly."
The dock features a USB charging port as well as an audio out and enables the tablet to be displayed at a neat viewing angle when sat on a desktop or coffee table.
As well as a dock for the award-winning Nexus 7 tablet, a station for the larger Nexus 10 is also thought to be on the way.
A festively-themed Android promotional video showed off both the Nexus 7 and Nexus 10 docks before their official announcements
