#53Impressive for a 16GBP watch !
Xiaomi mi bands used to cost the same and were much better
I bought one. The touch screen was not good. The heart rate sensor was wild inaccurate at times. It was a pain to sync with my phone. And the strap gave me a rash.
Not that I expect the watch in the article to be any better.

#54People get surprised how cheap things really can be when they see aliexpress, and the assumption is crap. I bought a ton of stuff from aliexpress, and very rarely-if any- was crappy.

#55As someone who loathes jewelry on myself and has no interest in the watch culture, nonetheless I have an interest in smart watches I can monitor things with. I'm turned off by big ugly blocks with childish straps.. is there anything remotely attractive?
This company which was reviewed in the article has a ton of smartwatches. This is the URL - https://www.colmi.info/
Pick what you like and then search for the same model on Aliexpress. You will usually find most of their models between $10 and $30.

#56> 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 is insanely common.
I have about 6 devices with this problem, and I consider it unforgivable.
Not only did you not include USBC charging, you went out of your way to trick me and lie and pretend you did. I would have preferred just using micro usb at that point.
Powkiddy committed fraud and said the RGB30 can charge from USB-C, but they lied, it can only charge from USB A to C cables. Using it is a massive pain because I have to get adapters I shouldn't need. I'll never buy anything from them ever again.

What I've learnt from BigClive on YouTube is don't buy anything that plugs into the wall.
If it's low voltage then you should be fine. I'd still be wary of large lithium ion batteries, though.

#58Earlier quoted context omitted.
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…
This happens because these devices had USB microB before and the manufacturer just replaced the port without reading the spec. Even some mainstream products have this issue. I have an automatic door opener from a large company and the battery pack has the same issue. It is shipped with a special cable you have to use as no other USB-C cable works.
There is also another problem. The spec is large and it's not aimed at those who want to implement the simplest possible USB C compliant device.
Based on the table of contents the most promising section is "2.3.4 USB Type-C VBUS Current Detection and Usage" but it doesn't actually talk about anything you actually need. You're supposed to click through to the section "4.6.2.1 USB Type-C Current" where it shows the reference circuit, but it doesn't tell you the values of Rd, which are in section "4.11.1 Termination Parameters".
It's a 300+ page document where you must already know what you're looking for. If you didn't already know that you need two resistors, you wouldn't be able to figure it out with the spec alone.

I feel like the USB committee might be somewhat to blame. When most people think USB-C they're just thinking the cable. Why can't it just do regular slow charging with C to C cable?

#60Hoping for open source watch OS some day, so many OEM / white label cheap smartwatch/fitness bands. Already exists for cheap cloud cameras. Could be the F91W of our time.
Also I'd gladly ditch USB C for a few programmable media buttons. Standardize on some sort of bogo pins and buy 20 adapters or split cables to keep the water proofing.
