Microsoft hints at battery-equipped covers for Surface →∞ Wed, 6 Feb 2013 · Comments
The Surface team is currently doing an AMA (Ask Me Anything) on Reddit in preparation for the Surface Pro launch. Here’s an interesting answer I noticed in response to someone asking whether there were any plans for an external battery or a keyboard cover with an integrated battery:
That would require extending the design of the accessory spine to include some way to transfer higher current between the peripheral and the main battery. Which we did…
And another one:
At launch we talked about the “accessory spine” and hinted at future peripherals that can click in and do more. Those connectors look like can carry more current than the pogo pins, don’t they?
This strongly implies that it’s technically possible to charge Surface through the connector for the Touch and Type Covers, which would open the door for future keyboard covers with some sort of integrated battery.
Update: The Verge points out that the Surface Pro has some additional connector plates compared to the Surface RT, so if those future accessories ever materialize Surface RT owners (like me!) might be out of luck.
