Yoga 720 13" not charging via 27W usb-c charger

2018-06-12, 3:22 AM

i'm trying to charge via the essentialphone charger which charges at 9v 3a (27w) but it's not working. it SEEMS to be able to keep it not discharging, however it doesnt charge. and if i turn off computer, it still doesnt charge.

 

very weird?

Not weird.  The 720 needs 20V to charge.  If your adapter can't provide that or correctly negotiate that it's not surprising that it doesn't work.
