    that's the design reason they went with a separate charger as opposed to USB since the max you can push through that is 5V. I need to plug the wall charger up to a Kill-a-Watt to see what the draw is (plus see if the wall charger is a power vampire)
    I'm sure you know this, but it's not voltage that determines battery charge time...

    Plugged into my kill a watt the Surface pulls 25W charging and 0 when not so you can leave the wall wart plugged in when not in use, it isn't a power vampire.

    That's good to know, What's the kill a watt thing? I'd like to check the chargers for all my stuff.

    oh also, this goes without saying, but the Surface adapter is smart, the watts drop as it fills up, towards the end it goes to a slower charge of about 6W. All this together means it charges a lot faster than iPad charger, which takes 3 hours I've seen to top up.

    Hi I was wondering how quick the battery is supposed to drain when it is locked. I just received my surface from Best Buy and have noticed that the battery drains awfully fast. Last night I turned off Notifications and Bluetooth along with putting it into airplane mode. It had 23% battery, when I woke up this morning it was dead. I am still in the exchange window so I was wondering if this is normal?

    Not normal, but make sure you have installed ALL updates.
