Someone forgot to post to sale.
Relatively useless not to have info on charging rates per USB port. Reading between the lines, it looks like a bare 2.1W per 2 ports max.
That’s what I came here to see - thought someone might have asked the question and gotten a response. I certainly wouldn’t buy this until I knew the specs. If the amperage quoted is to each USB-A and USB-C port then I’m interested. If that amount is split between ports, I’ll pass.
This would indeed be valuable information. I think the current output would be fine for bedside, overnight charging duties. I wouldn’t expect much more at this price point. At the pointless price, on the other hand, it should charge instantaneously and wirelessly!
Of course, it would be better if it were smart. 
Darn. Was going to bite but realized that these are designed for the old outlet type - not the newer deco (rectangular form) outlets - meaning the unit itself, not where the good old US standard plug goes in. Also, that center mounting screw would go right into the buttons for the GFCI outlet. A shame, as I wanted to put this near our coffee maker to have a charging center for my wife’s Apple devices.
Got these and they work great, but the included screw is too short to engage in most outlets. Needs to be a 2.5" screw instead of the included 2".
A quick trip to HD resolved this issue.
