First thing's first: all such adapters should be considered evil by default. The only way to make a compliant adapter is with active circuitry in the adapter essentially providing an entirely standalone USB controller interface.
With that being said, here's an adapter which does exactly that. Back when I researched this topic in October I found that the linked adapter is essentially the only one of its kind on the market right now.
Yeah, those are CONSIDERABLY bigger than USB A to USB C dongles
Like I said: in order to do it the non-evil way you need to cram in an onboard USB chip. Female USB-C from a Male USB-A plug-in is explicitly not possible to implement in a spec-compliant manner because of the pinouts.
You can brute-force a smaller passive adapter like those online but it's a devil's bargain. Nobody targets these janky adapters when designing products. USB-C things will just break without any rhyme or reason because you're fundamentally breaking the hardware contract and "lying" about the capabilities of your port.
FYI essentially all adapters with a usb-c female connector are non-compliant.
When people talk about USB-C potentially damaging devices, it is because of non-compliant adapters, chargers, cables, etc.
So just keep in mind that while the risk may be minimal depending on your use-case, these adapters can be dangerous and risk damaging your devices.
FYI essentially all adapters with a usb-c female connector are non-compliant.
Can we take the word of a random internet stranger without even SOME context or explanation?
Here's an article that mentions it
As a rule of thumb, most adapters with a female USB-C socket on them are non-compliant.
You can also look at the USB spec yourself
USB Type-C receptacle to USB legacy adapters are explicitly not defined or allowed. Such adapters would allow many invalid and potentially unsafe cable connections to be constructed by users.
USB A doesn't have Power Delivery, the highest it can do is 15W for USB 3.2 and 4.5W for USB 3.1 and older.
But these dongles exist, I bought some and they work for charging (I haven't tried to use them for data)
You can't really get 15 watts from a USBA port, but this may be the adapter you want: https://www.adafruit.com/product/4175
Seems there only in rose gold at the moment, I got a pair of silvers last year and they work exactly as you'd want them to work.
