You can't make USB-C power delivery with just two wires (unless you stick to very low power delivery). The sides have at least to negotiate voltage for reasonable power to flow (max current is, ISTR. 3A, which'd make 15W at 5V: I shudder at the thought of 3A going through those pins). But I agree: there should be a very clear way of communicating that on the package. My solution is a brick-and-mortar store where the folks know what they are doing. A luxury, but my city has that :-) Cheers -- t
