Review on UL Listed 90W 65W CAR Charger for Lenovo ThinkPad X1 Carbon X1 Yoga T Series T470 T470S T460 T450 T440 T570 Laptop Power Supply Cord by Alexa Gay

I bought this brand new unit on August 29th 2018. It was working great, but on January 1st, 2019 it stopped working. The manufacturer says it must be a faulty outlet that tested and charged everything else. Including another laptop that needs more power and the blue light on the charger itself comes on and then says doubt for a few seconds and doesn't even show on the laptop that it's even connected. For being so expensive it's a waste of money and very frustrating
