HyperDrive USB-C Hub + 7.5W Qi Wireless Charger iPhone Stand
The HyperDrive 7.5W Wireless Charger USB-C Hub came from a Kickstarter in January 2018 that raised US$657,117. I missed the early-bird US$79 price, so my friend Kevin helped me get it; it finally shipped to me in July 2018.
Mophie Wireless Charging Base
The Mophie Wireless Charging Base is one of two Apple-endorsed chargers that fast-charge the iPhone 8/8 Plus/X at 7.5W; my benchmarks confirm non-endorsed pads don't. It retails for S$99 at Apple, though I picked one up in Japan.
