The keyword is "PD 诱骗头", which is a small converter to trick the power supply to output at full capacity. Not sure if it's safe, but it's tempting to replace the big power adapter that comes with NUC with a small GaN USB C PD adapter.
Even better, there are "PD 诱骗头" for Surfaces, ThinkPads and other laptops using proprietary DC ports. Try searching "PD 诱骗头" + "<your laptop's brand>" in alibaba/taobao.
Not sure there's anything inherently unsafe about outputting the power supply at full capacity.
This is likely just an actual PD controller that always tries to negotiate the maximum power. Nothing wrong with that.
The second link if it's actually outputting max voltage/current over the USB Type-A: that's probably not safe. I don't think any USB Type-A connector is rated for 5 amps. Don't think there should be any issue with the voltage, besides the fact you'll fry any regular USB device if you plug it in...
