I tried charging my Surface Go using the USB-C port connected to a cell phone charger, and while the device says that the charger is connected, it isn't able to actually charge. I assume I need to use a more powerful charger. I'm considering trying the charger that came with my Amazon Fire HD10 which is a 5.2v 1.8amp "9W" charger. Just wanted to be sure it isn't going to be harmful to the Surface Go before I do.
