the question is highly imprecise you didn't say you need male/female on which side But, to be constructive, C receptacle to legacy is not allowed by the specification when they are passive which most of Amazon crap are -- but Benson found active ones https://old.reddit.com/r/UsbCHardware/comments/m7rcu5/any_reliable_usbc_female_to_usba_male_adapters_yet/ More on reddit.com

Those adapters are potentially dangerous and forbidden by the USB C spec. It is possible to do them correctly, but I doubt the no-name thing you got at the auto shop is doing that. It's no surprise this spec violation is low quality. They're ripping you off with shoddy products. The simple answer here, as u/avidee said, is to use an A to C cable. Any such cable will do if all you care about is charging, and they're cheap -- you can get an Amazon Basics USB 2 cable for around the same price as that shoddy adapter on Amazon. Note that if you have a non-Pro iPhone 15, those don't support USB 3 and so any A to C cable will work at max speed there too. Regarding adapters -- the only good ones I know of are the ones from CableCreation. The thing to understand is that getting these adapters right requires active circuitry -- you need muxing to deal with reversible USB C cables and you need to not present 5 volts on V_bus unless the connected device presents itself as a sink. The time it makes sense to use these adapters is if you have a device with a captive USB C plug that you want to plug in to an A port. It doesn't make sense to get one just to adapt a simple passive cable. Regarding these specific adapters: my guess is that (on top of almost certainly having the V_bus hot short risk) they get the resistor signaling wrong and have exactly the old "56 KOhm" issue that many early defective A to C cables had 7 years ago. The net result is that he phone thinks it can draw 3 amps when the port on the computer is only expecting to provide 900 mA. That could cause damage to the port but will most likely just cause the port to shut off. One experiment to confirm this would be to try using the adapter with a fully 100% charged phone which will likely draw less power. More on reddit.com
