This was a pretty popular deal previously and it's slightly cheaper this time around. You can read the comments there.
There are a couple of additional variations that include a cable as follows:
Adapter + 1m cable was $25.99 now $20.79
Adapter + 2m cable was $26.99 now $21.59
What makes this better than say the Consol 20W USB-C PD fast charger from Officeworks for $19.80?. It supports Apple Fast Charging according to the rear of the product box. Also has a 2 year warranty from OW.
