Our bad! We updated the sale and got rid of the box.
Be careful. I got one of the 12.9 refurbs from Woot a few months ago. It came with a generic 15W USB-A power adapter and a generic USB-A - to USB-C cable. Apple supplies an 18W adapter and USB-C to USB-C cable. This is important if you want to use something like the Plugable USB-C adapter that supports power pass-thru on the USB-C port. The generic supply will not charge the iPad when used with the Plugable adapter installed. Not sure if it’s the lower wattage or the USB-A to USB-C cable (or both). But using a genuine Apple 18W adapter and cable works fine.
