I wanted a simple dumb USB power lead, basically from USB-A with GND and 5V to a USB-C plug, for my coasters.
I looked and I looked, I could not find anything simple. Indeed this is typical of the things I found:-
As you can perhaps see, it shows a lot of active components in the USB-C plug. Indeed, it claims advancements from 2018 (1A) to 2020 (2A) and 2022 (3A) charging, perhaps justifying these many active components.
I did not want that, I did not even need D-/D+ connecting, just GND and 5V, so I looked and looked, and eventually decided to get some anyway. Basically as long as they worked for power, I could ignore the extra "tech" that may be in there.
I suspect you can all guess what happened next...
I got an extra lead, so I could cut it open. It is surprisingly hard to cut off the plastic/rubber with a broken elbow and bruised wrists, but I managed...
Yep, there are no active components, this is, indeed, just GND, 5V, D- and D+ connected. Indeed the other side is not much more and seems to be one resistor fitted. It may be there were 2 and I killed it with a pen knife - that would be consistent with CC1/CC2 connections to tell a device this is a dumb USB-A passthrough.
So this is what I wanted, a simple GND/5V pass through.
But in what way could this remotely be an improvement from the 2018 1A design or 2020 2A design? I mean how is this remotely as depicted. How is this remotely legal advertising?
Update: They are offering me a full refund, if I ask for it - wanna bet it will be in exchange for cancelling review? TBH not bothered about a refund.
