Yeti 500X to charge Macbook Pro 16''

When using USB-C PD to charge a Macbook Pro 16'' the charge does not work, but only the Macbook rings continuously. Also, the Yeti's display shows 0 W from Output. Is this particular unit wrong? I purchased 2 of them and they acted the same. In the advertised video here (https://www.goalzero.com/collections/portable-solar-generator-kits/products/goal-zero-yeti-500x-portable-power-station-boulder-100-briefcase-kit) shows the Yeti can charge Macbook Pro through USB-C PD. Can someone tell me what is wrong here? Why I can't charge the laptop with USB-C PD?

Thanks!
