And tell them what? That a device that is neither a mobile phone, tablet, nor camera [1] is using a charging port that's not USB C?

"Regardless of their manufacturer, all new mobile phones, tablets, digital cameras, headphones and headsets, handheld videogame consoles and portable speakers, e-readers, keyboards, mice, portable navigation systems, earbuds and laptops that are rechargeable via a wired cable, operating with a power delivery of up to 100 Watts, will have to be equipped with a USB Type-C port."
