Marketplace
At least 50+ units at Bunning Chatswood, NSW store.
There are two types of adaptor. one is AU inbound and USA/UK/HK outbound. one is AU outbound and USA/UK/HK inbound as you can see from the picture. I suppose it is the same price.
Both with 1 USB A + 1 USB C port. Max output is 5V x 3.1A as stated in the box.
If you buy both types and piggy back, you can convert AU to AU…
(Hope this helps someone…)
