Terence Eden’s BlogWhy don't smart watches use USB-C to recharge?<a href="https://shkspr.mobi/blog/2025/08/why-dont-smart-watches-use-usb-c-to-recharge/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://shkspr.mobi/blog/2025/08/why-dont-smart-watches-use-usb-c-to-recharge/</a>It looks like the new Google's Pixel 4 watch comes with <a href="https://www.androidheadlines.com/google-pixel-watch-4-charging" rel="nofollow noopener noreferrer" target="_blank">yet another incompatible change in charging technology</a>. This is a ridiculous situation.The original Pixel Watch used <a href="https://www.techradar.com/health-fitness/smartwatches/your-google-pixel-watch-now-charges-more-slowly-but-that-might-not-be-a-bad-thing" rel="nofollow noopener noreferrer" target="_blank">one type of wireless charging</a>. Then the Pixel Watch 2 & 3 removed wireless charging and <a href="https://www.androidcentral.com/wearables/can-you-charge-the-pixel-watch-2-with-a-fitbit-charger" rel="nofollow noopener noreferrer" target="_blank">swapped to a different charging mechanism</a>. And now the 4 has changed again.So three different charging cables in under three years. Progress!While it would be lovely if watches could support Qi charging, they are just too small to make it work effectively - which is why <a href="https://www.anker.com/blogs/wireless-chargers/will-apple-watch-charge-on-any-wireless-charger" rel="nofollow noopener noreferrer" target="_blank">Apple has a proprietary wireless charging system</a>.So, why not use everyone's favourite mandated charging standard - USB-C?<a href="https://www.theverge.com/2022/10/14/23404283/pixel-watch-wireless-charging-qi-wearables" rel="nofollow noopener noreferrer" target="_blank">The Verge</a> says:<blockquote>These devices are too dang small, and the technology isn’t there yet. Most standard connectors, like USB-C, are too large to fit within a smartwatch or on devices that are meant to mold to your body. The smaller the device, the more difficult this becomes.</blockquote>To which I say:<blockquote>Bullshit!</blockquote>Watches are small, but the USB-C connector isn't massive.Here's <a href="https://www.kickstarter.com/projects/unawatch/meet-una-the-modular-gps-sports-watch" rel="nofollow noopener noreferrer" target="_blank">a modern smartwatch which uses USB-C</a> for charging and data:But having a USB-C connector means water ingress, right? Wrong!<blockquote>Does this USB-C connector affect the waterproof rating? No, it doesn’t as the USB-C connector on the watch is IPX8 rated, meaning the internals of the watch are completely sealed from the outside of the connector.</blockquote>OK, the port itself might get water and dirt in it - but a lug will seal it.Still, that watch is over £200. Not bad for a pretty high-tech gadget with a limited supply. Are there others?Here's the <a href="https://s.click.aliexpress.com/e/_oCwt0hW" rel="nofollow noopener noreferrer" target="_blank">Colmi P80</a><a href="https://s.click.aliexpress.com/e/_oCwt0hW" rel="nofollow noopener noreferrer" target="_blank"></a>It's a pretty basic watch - although it claims to do heart rate and blood oxygen monitoring. It may be crap for all I know - but it only costs £16!In the middle of that price-range is this <a href="https://s.click.aliexpress.com/e/_onOqpH2" rel="nofollow noopener noreferrer" target="_blank">£80 smartwatch which is actually an entire Android device</a>!Again, with USB-C built right in.And, yes, it might be rubbish as both a watch, Android device, and masc-coded jewellery - but it shows that USB-C is viable for devices of this class.Why USB-C?I don't want to have to buy new accessories every time my hardware changes.I already have hundreds of USB-C cables.I only want to take one cable with me on holiday to charge my various gadgets.I don't want to be restricted to only buying products from one company.I want something which isn't going to be knocked off its charging pad by a particularly strong fart.So I've bought the £16 AliExpress special and will review it shortly!<a rel="nofollow noopener noreferrer" class="hashtag u-tag u-category" href="https://shkspr.mobi/blog/tag/gadget/" target="_blank">#gadget</a> <a rel="nofollow noopener noreferrer" class="hashtag u-tag u-category" href="https://shkspr.mobi/blog/tag/usb-c/" target="_blank">#usbC</a> <a rel="nofollow noopener noreferrer" class="hashtag u-tag u-category" href="https://shkspr.mobi/blog/tag/watch/" target="_blank">#watch</a>

Modern USB-C cables contain <a href="https://hackaday.com/2023/01/04/all-about-usb-c-resistors-and-emarkers/" rel="nofollow noopener noreferrer" target="_blank">little microchips called eMarkers</a> which allow them to transfer data and power at terrifying speeds. But, sadly, there's no way you can look at a USB-C cable and see whether it supports the <a href="https://en.wikipedia.org/wiki/USB-C#Cable_types" rel="nofollow noopener noreferrer" target="_blank">baffling array of features</a> available.Enter the catchily-named <a href="https://treedix.com/products/treedix-usb-cable-tester-usb-c-cable-tester-usb-tester-for-data-transmission-and-power-transmission-cable-testing-resistor-testing-type-c-emarker-for-usb-a-micro-b-micro-b-3-0-type-c-lighting-mini-b" rel="nofollow noopener noreferrer" target="_blank">Treedix TRX5-0816-AC</a>.It will test just about any sort of USB cable and tell you what it does - and doesn't - support. It will also show you which pins are connected, how fast it can transmit data, and what the eMarker shows. Nice!Let's put it through its paces.Inputs and outputsOn one side are your output ports - you have a choice of USB-C or USB-A 3.0.At the bottom you have this range of ports to choose from:So you can go A-C, C-micro, C-lightning etc.Finally, on the other side you have a button, a switch, and input power:The power switch toggles between the internal AAA battery (included) and a 5V supply from a USB-C cable (not included). Pressing the white button moves between the different diagnostic screens.Power OnlyI tried with a short USB-C power-only cable designed for charging low-power devices. I plugged in the USB-A end and the USB-C end.It correctly identified that it couldn't do data transmission.With a power-only USB-C cable, it had much the same display. Pressing the button on the side of the Treedix told me what it knew about the eMarker.Perfect!Passive USB-CWhat about a data and power USB-C cable? This is the <a href="https://shkspr.mobi/blog/2023/08/chubbycable-usb-c-review/" rel="nofollow noopener noreferrer" target="_blank">ChubbyCable I reviewed a few years ago.</a>USB 3.2 Gen2 and power of up to 100W. It has also correctly guessed the likely length of the cable by measuring the latency.Interestingly, when looking at the basic functions, it says it can only do USB 2.0 speeds and correctly identifies that it doesn't do PowerDelivery 3.1 (which goes up to 240W).Finally, which pins are connected?That looks about right!ThunderBolt 4 or 3?Let's compare two high-performance cables. The one I usually have plugged into my <a href="https://shkspr.mobi/blog/2024/06/review-framework-16-laptop/" rel="nofollow noopener noreferrer" target="_blank">Framework Laptop</a> and <a href="https://shkspr.mobi/blog/2023/08/gadget-review-mokin-usb-c-docking-station-linux-information/" rel="nofollow noopener noreferrer" target="_blank">USB-C hub</a>Thunderbolt 4 capable of 100W of Power and 40 Gbps of data. As expected, no PD3.1:Let's test a different high-quality cable I bought recently. The labelling claims 20Gbps and 240W of power. We can see that it does have PD3.1:But! Looking at the eMarker, it reports that is only a ThunderBolt 3 device capable of 10Gbps!I asked the cable manufacturer if that's a problem with the cable or the eMarker or the diagnostic machine. They said:<blockquote>eMarker tester can only show single channel transmission rate 10Gbps, devices supporting dual channel can show 20Gbps. our products have 18 months warranty, if there is any problem, please feel free to contact me, I will provide you with satisfactory after-sales service.</blockquote>I've contacted Treedix to see if they can shed light on this.Of course, my laptop only supports 10Gbps, so it is a bit moot!Weird CablesAs well as your standard USB-C, it will also do the ugliest plug known the mankind - the USB Micro-B SuperSpeed.It'll also do Lightning cables - as long as they also have a USB-A or C end.DownsidesOther than having to replace all your duff cables, there are a few annoying little niggles.<ul><li>The battery compartment is really stiff. I had to unscrew the back of the device to get it open.</li><li>The power switch feels a little flimsy.</li><li>The function button is a little small and fiddly.</li><li>Screen brightness can't be changed (but it is pretty bright).</li><li>No USB-B (the chunky one often used for printers).</li><li>No firmware updates.</li></ul>Those are all minor complaints.The biggest complaint is that USB-C terminology is hard. Which is better, 40Gbps but only 100W or 10Gbps but 240W? How does ThunderBolt relate to USB? What is EPR and why does it matter? Where does DP Alt Mode fit in?!VerdictIt powers up and detects all features instantly. It goes to sleep after a few minutes of not being used. It will even show you the electrical resistance of the cable if you think that's useful.Total cost? <a href="https://amzn.to/44eJ7YL" rel="nofollow noopener noreferrer" target="_blank">£40 at the moment from Amazon</a>. I reckon that's a bargain. It is an indispensable piece of kit - especially if you have a big box of ancient USB cables. This will allow you to quickly and easily see which ones are broken, which are mislabelled, and which deserve pride of place in your collection.If you're running a hackspace, this is a no-brainer.
