I bought this specifically for my switch in tablet/portable mode and it works great. I found this out because I have easier access to ethernet connections than wireless. I downloaded Bayonetta (8.5GB download) in just 27 minutes. I've played Splatoon 2 online matches with it and it works great there. In about 30 minutes of online play, the battery went from 100% to 83% just to get an idea. Of course you can't charge the system with it, but other than that it's amazing. I'm VERY happy with mine so far.
