    The Surface RT comes with a 24W power supply. The Surface Pro comes with the 48W power supply. Will the 48W power supply charge my Surface RT faster or is the extra wattage just for the usb port on the power supply?

    Not gonna charge it faster. You can use the RT power supply on the Surface Pro though, it'll just charge it slower.

    I would strongly suggest checking with Microsoft on this one. They have conflicting information on the Surface page and Microsoft Store page. One says they are each compatible with both devices and the other states explicitly that the 24W adapter is exclusively for RT and 48W is exclusively for Pro.

    it doesn't matter, I've analyzed the carge process with a Kill a watt and the wattage drops as the battery gets charged to capacity. It is going to take the same amount of time because the surface backs off the charge.

    the 48W charger works for RT but I don't think it'll change the charging speed. Pro has a 48w charger because it requires more power when being used.. so for the battery to still charge more power need to be supplied.. advantage of using 48w charger with RT is the extra USB power port and extended power cord.

    Actually, yes it will work (Surface battery | Surface power | Recharge Surface), and yes it will charge faster (although the post doesn't mention it, I am pretty sure it was covered in the recent Reddit AMA with the surface pro folks I am Panos Panay with the Surface Windows 8 Pro Engineering Team AMAA. : IAmA)

    I was also looking for this info. I found this reply by an official Microsoft employee:
    "The 48-watt power supply included with your Surface Pro (or purchased separately) can be used to charge Surface RT. The 24-watt power supply designed for Surface RT can be used to charge Surface Pro, but the charging will take much longer."

    This info can be found on the following page:
    http://answers.microsoft.com/en-us/s.../20cd21ff-8fa5

    So both can be used for the 'wrong' device. The RT charger will charge the PRO slower (24w) while the PRO charger will the RT at a normal speed (without frying the circuits). I am using both chargers/devices and am now mainly using the 48w PRO charger.
