How did support handle this situation when you reached out?

I tend to take a picture of the barcode / proof of purchase with my phone and tag it with the item name before I chuck the box. The one issue I had with an anker cable I submitted a ticket with a picture of the defect, picture of the proof of purchase / barcode and the invoice from Amazon. New cable arrived in a couple days. I was impressed. Their stuff seems to hold up.

Any more details on where you sourced the charger / cable? Power supply? US/EU?
