Microsoft has started taking orders for the Power Cover for the Surface, six months after announcing the keyboard with extra battery life at the launch of the Surface Pro 2 and Surface 2.
Back in October, Microsoft promised the Power Cover would arrive in early 2014. It's now available for order - in the US at least - and will ship on 19 March for US$199. Australian availability and pricing has yet to be announced.
The Power Cover is the third cover in the Surface range, alongside the Touch Cover and the Type Cover, the latter of which has physical keys.
The Power Cover is much the same as the Type Cover, but is slightly thicker and heavier thanks to the addition of an integrated battery. That helps extend time between charges to ten hours, Microsoft said at the launch.
At the time, PC Pro suggested it may be worth "postponing a purchase until this keyboard becomes available".
The cover works with the original Surface Pro and Surface Pro 2, as well as the ARM-powered Surface 2, but not the original Surface RT.
Surface 2 LTE
Leaks suggest the Surface 2 is also set to get mobile broadband support, according to Bit-tech.
Microsoft's vice president for Surface, Panos Pany, said last September that the Surface 2 would get mobile broadband support in "early 2014".
Like the Power Cover, Microsoft looks set to deliver soon with an LTE-enabled Surface 2 reportedly set to arrive in the US on the AT&T network. Also like the Power Cover, there's no word on Australian availability.
