This Samsung Convertible Fast Charge Wireless Pad (2017 model) was very popular in this deal from TGG https://www.ozbargain.com.au/node/322367
It's slightly more expensive now at ~$71.10, but this is US model, which comes with Adaptive Fast Charge Adapter + USB type-C cable (same as the one provided with S8/S8+)
Only Tan colour available at this price (I think this colour isn't available for sale in Australia?). Cheapest according to 3xCamel.
Should be compatible with new iPhones?
