Apple 20W USB-C Power Adapter retails for S$29 or S$25.68 if your company is on Apple’s Employee Purchase Plan (EPP).
Like most Apple products being sold, it doesn’t come with anything extra. So no USB-C to Lighting cable or USB-C to USB-C Cable is included in the packaging.
This is a 1-port 20W USB-C wall charger with a folding UK 3-pin head. It is not using GaN technology since it is only 20W.
It seems that this is a USB-C Power Delivery 3 (PD 3) charger. And to get 20W of power, Apple uses the 9V/2.22A power profile of the PD 3.
I bought this so that I can test it alongside other USB-C chargers to see if the Apple MagSafe Charger charges at full speed of 15W for all USB-C chargers.
I will create another post on that when my tests are done.
