I found out a method to charge the switch faster with a powerbank. With this method i was able to play breath of the wild and still charge my switch while playing. The powerbank i used is this one: http://smartpowerbank.blogspot.de/2013/07/anker-astro-e4-13000mah-external.html Max output is 5V/2A so nothing special and no quickcharge technologie or something similar. I used a standard USB to USB-C cabel. How i managed to charge the switch faster: 1. Start a game (no powerbank connected) 2. Take the Switch into standby mode 3. Connect your powerbank to the Switch while it is in standby mode 4. Go out of standby mode and resume your game. 5. Your switch should load much faster now. It seems like the Switch goes into a diffrent charging mode while in stanby and will keep this charging mode as long as the powerbank is connected. I was thinking about buying a new powerbank, but with this method, i don't need one anymore =). hope i could help u .
