Review on UGREEN Extension Extender Compatible Thunderbolt by Sharon Johnson

UPDATE: After re-evaluating the cable, I connected it directly between the AC adapter and the MacBookPro and it worked. Power -> Dock -> MacBookPro) and that worked too. I don't know if there was dirt on the cable initially, if there was a bad contact (it was a brand new MBP), but now I'm very happy with this cable. Does what it should: load data etc.
