Usb C has a default of 5V, 2A. This matches/exceeds the micro USB standards. In order to get a higher voltage, it negotiates up. (Or it's supposed to! China can produce some NASTY exceptions!)

I'd recommend making sure whichever ones you buy explicitly say in the description that they support charging/data transfer (depending on what you want out of them) I usually end up using Amazon since it's just harder to find these at any in-person retail stores, or other online retailers, so check their product images for those claims as well.

Most of them are sold by dropshippers, that don't care much about the actual functionality of their tech, so when they explicitly put it in there, it's usually because the original manufacturer listed that feature too.

If any of them don't match the specs (don't charge/transfer data) or don't match the images (have a logo when it showed no logo), contact Amazon support and they'll usually give them to you for free. In my experience (having bought 7 completely different adapters from various sellers) they usually work as advertised in the description, although I tend not to trust anything claiming it meets fast-charging standards. That's usually bogus. (good thing to tell Amazon support to get them for free though 😉)

I coincidentally bought these ones recently. They didn't have a logo in the photo. They arrive, whaddaya know, they have a logo. Contacted support, they gave me a full refund.

Yeah, I think so...

I do have some micro usb devices that won't work with some newer Power Delivery Adapters, but it's the brick part, not the USB C cable since the same cable / adapter will work with a different brick.
