Unfortunately, it seems that anything over 5W will not charge the laptop, can anyone confirm?
I use this one on the 5x – https://www.gearbest.com/chargers-cables/pp_624045.html
It works great and on the plus side can also rapid charge my phone with it. wait for it to go on special though. I didnt have the same issues charging as chris did though, as for the battery meter you just need to give it a few minutes to reflect the proper “time to full” when its plugged in. it seems to ramp up the voltage intake gradually. but after that its pretty quick to charge.
