Question: Is this compatible with the Surface Pro 3 that just came out?
Document: Works great. No issues. Powers up my surface pro in good time and I haven't had any issues of the charger failing.
Looks good, matches my Surface Pro, works well, and has a USB port. Sure, you are get off-brands, but why risk frying your machine.
Bought 2 of these and both did not work. I have a Surface pro 2 and I made sure to get a 48 W power supply. One of the two connected and the unit said plugged in and not charging and the other was not recognized by the system. The company gave me a full refund. I would buy from them again!
I find I have to fiddle with it for a few seconds before it finally snaps and connects. As the case on the Surface Pro and the connector on the power supply are metal, you'll find that after the first few connections you've scraped off some of the black finish of the Surface Pro.So overall I knock a point off for the annoying magnetic connector, but otherwise it's a power supply and seems to be made well and charges the Surface just fine.
I bought this charger used (heavily discounted) and it didn't come with the cord that goes from the wall to the charger. I was going to order one, but I found one around the house. It charges my Surface RT faster than the charger it came with, and has a USB charging port too. For these reasons, this charger lives in my travel bag. Check out the amazonbasics laptop/tablet bags, very reasonably priced.
I was going to get this item here until I looked at the microsoft website and saw it was about twenty five dollars cheaper. I always turn to Amazon but I'm starting to see more and more price gouging. My advice is to check the microsoft site and decide from there where to get this much needed accessory...always good to have 2 adapters and one with a USB charger is great being the surface pro doesn't have enough of them anyway.
I like the USB 3 pass through and it is reasonably small. Not really digging the whole magnetic connector thing
well it's smaller than the 84w macbook pro brick and much lighter. It also comes with a USB port for charging other devices. Quick shipping
Not sure why the surface does not come with this charger, it is great for charging surface and phone at the same time.
Magnetic connection to the Surface so you'd expect it to be easy to insert like a MacBook. However, it's impossible to line it up right without looking closely. Does not snap together like the rest of the unit (pop out stand for instance). The USB charger is a plus considering the Surface only has one USB port.
Answer: It is not compatible.  Only work with Surface Pro 1 and Surface Pro 2.
