> The watch is simply missing the two 5.1k resistors connecting the CC1 and CC2 pins of the USB-C connector to ground that are required to indicate to whatever is plugged in that it wants 5v power. This is so annoying. Back when USB-C was less prevalent, I bought a pair of wireless earbuds over another for the same reason as the title - because it used USB-C. But then I cannot charge it with my macbook, unless I add…
This problem seems prevalent on cheaper devices. When I buy a device and discover it has this problem I always return it. I've seen it on the Hypervolt Go 2 (which I returned and replaced with a Theragun Mini) and on the Hitachi Magic Wand Micro (which I replaced with a Dame Dip). Like the post mentions, I think this happens because the devices are missing two resistors that are needed to indicate, when connected via…
I’ve seen it on plenty of higher-end devices as well; and even worse.
The worst offender I’ve encountered is the TermoWorks Billows. ThermoWorks is a well established brand that makes high end thermometers and is considered one of the best on the market. So I was quite surprised to discover how their ‘Billows’ product is powered.
The device itself needs 12v and has a USB-C port for power. You’d think it would do USB-PD to negotiate it’s power needs so you can just use any old USB-C adapter. Not the case. It comes with a USB-A to USB-C cable and requires a special adapter with a USB-A port on it that puts 12v on the pins that normally supply 5v.
I have no idea how they came up with this abomination. Why even use USB-A connectors if it’s not going to work with a standard USB-A adapter, and why supply an adapter that’s basically going to kill most USB-A devices you plug into it? If you have a custom adapter anyway, why not just use a simple barrel connector? Why put a USB=C port on the device if it can’t use USB-PD?
I can imagine some Chinese ali-express product using such an abomination to save a few cents on components, but why would a well-respected brand like ThermoWorks ship such a thing? It boggles the mind.
