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.

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?
