Both work perfectly on proper USB-C and charge. They were both $15 or less. The kind of device where every cent on the BoM may matter.
The devices in my original comment? Hundreds of dollars each. They have to go through certifications to prove they do what they say. The price of two resistors (they don’t need more power) is nothing compared to the MSRP which I already suspect has a lot of profit baked in.
There is no way to guess if a device charges right or not without finding the logo (which I guess could be a lie from an unscrupulous vendor) or finding reviews.
