Microsoft Surface 24W Power Supply

I like that this one is more like the chargers my Macbook Pros use, folding plug and no second cable to go from outlet to power supply. It *DOES* work great with the Pro, just is supposed to take longer to charge since it's obviously a less powerful PS. The cable from the plug to the power supply is the same length as the one for the Pro, so you only lose the length of the second power cable from the wall to the power supply of the pro version. But in reality, depending on where you are, you may find MORE freedom since the power supply won't be sitting on the floor. I have an outlet on the wall behind my couch, and if I use the pro, it goes from the height of the outlet down to the floor where the power supply has to sit, then back up to my level. With the smaller RT power supply the cable goes right from the outlet to my surface in a straight line, so I actually end up with the same amount of cable to work with along with the benefit of not "tugging" on the larger power supply and sometimes lifting it in the air from the tension...

Smaller, no big cable to go to the outlet that doesn't coil well, far more portable. So as long as you're not absolutely requiring that you fully charge up from "forced to sleep mode" 5% charge to 100% in 2 hours or less, this is a much better one to carry around with you. I tested charging times with the larger power supply that came with the Surface Pro and will post that info along with the results of the same test using the smaller more portable 24W for a good comparison once I've finished.

Edit I just did a total draw down of the battery to the point less than 5% where it forces itself asleep. I plugged in this smaller power supply and it took me the same amount of time to get a full charge as the full sized pro power supply did just under 2.5 hours. So even more of a bonus. Maybe it won't charge it as much if you're using it concurrently, but if you just have it sitting asleep and plug it in, this one charges as fast as the larger one that comes with the Surface Pro...
