I spent most of yesterday looking at these sorts of devices on Newegg. There are plenty of USB-C docking stations, that feed power into the USB-C host device (if the host device supports USB PD "Power Delivery" charging), and a variety of video outputs (if the host device supports DP Alt Mode “Display Port Alternate Mode” and / or Thurderbolt 3) like HDMI, VGA, and Display Port. Usually including Ethernet ("for more stable connection"), card readers, some USB power / data, and maybe audio. Some of them just pass through audio from your MacBook. The great majority of them are for MacBook Pro. Very few of them mention using a phone as the host, but lots of them mention plugging in a phone to charge it. Slowly. For some odd reason, phones with PD charging can only accept 1.5 A through PD charging, but your laptop can accept much higher. At least according to those Newegg device descriptions that bother to mention that detail. Of those with a list of supported devices, typically they are MacBooks, Dell laptops, Chromebook Pixels, Samsung Galaxy from about 8 up, and several other recentish high end phones. Alas none mention my Motorola Z, nor Google Pixels. Priced anywhere between AU$70 and AU$300, though most seem to be Chinese clones. Possibly just rebadged from a single Chinese manufacturer. Since I already had USB-C dongles for audio and display (of the $5 variety), I also went looking for USB-C hubs, but all I could find was USB-C to multiple USB-A hubs, but at least some of them provided for getting power into your phone, though most had a OTG / power switch. So you could power your phone, or use your keyboard and mouse, but not both at the same time. Sadly it looks like there's no "one small device" solution for me, just "carry around a bunch of adaptors AND the bulky Moto Mod developer box, plus a wallwart". At least the Moto Mod dev kit leaves me with four usable USB ports, KVM and one of audio / Ethernet / power. Or add one of those USB-C to USB-A hubs. So yep, we can prototype the idea now, but I have my doubts that the world is ready for it yet. After all, why sell a cheap phone with a single USB-C port that can do everything via a cheap docking station that can be bought at your local supermarket next to their cheap USB keyboards, when you can make more money selling more expensive phones and lots of adaptors? Long ago as a teenager I used to enjoy reading hard science fiction where the protagonists could do wonders with modular technology that you could just plug it all into each other, and it would just work. I dreamed of growing up into that world. This isn't that world. This is Profit, Plug & Pray, toss it all into landfil, PROFIT! world. -- A big old stinking pile of genius that no one wants coz there are too many silver coated monkeys in the world. _______________________________________________ Toybox mailing list Toybox@lists.landley.net http://lists.landley.net/listinfo.cgi/toybox-landley.net
