Surface Pro 3 Charger Surface Pro 4 Charger

Works great. Happy with the size vs what I had before

I struggled to find a charger for my Surface Pro 4 after mine stopped working. I had a lot of problems finding one that worked. I ended up purchasing five, only two of which worked (see below for the links to the good ones). This is one of the ones that didn't work.It, like the other two that didn't work, messed up the trackpad on the keyboard (it's the office Microsoft Surface keyboard, not anything after market).When I plug the Surface in with this charger, the trackpad acts erratically to the point where it is all but impossible to use it. Typing seems fine, but using the trackpad isn't something that can be done.Using a USB mouse is doable, though, so this charger isn't going to cause any problems (that I am aware of) if you don't care about using the trackpad on the keyboard. The fact that it's usable without the trackpad is the only reason this isn't a one star review.Unfortunately, I waited too long to return any of the adapters, so I'm stuck with this thing and the other two that don't work. At minimum, I can warn you to not buy this adapter.----------------Here are the three adapters that DID NOT WORK (all of which caused the same problem with the trackpad):1) Brand: KSW KINGDO --- Surface Pro Surface Laptop Charger,65W Charger [Updated Version] Compatible with...
