Yes. The A4 and A9 (A1 and A19 are ground) are the only pins that transmit power. Putting 20V/5A through the copper is not a problem even for the cheapest cable

edit: Ok looking at the other reply with the link to the google engineers stuff some have messed up the A5 (configuration channel) pin and thus the negotiation for giving more power fails and just defaults to normal levels that are safe for any device.
- HPsquared 5y agoSure the wire can almost certainly handle it, but are the contacts always going to be able to handle 5A? They are very small after all, and not treated very nicely. Not sure how it's handled by the protocol, but I've known cables to get hot due to contact resistance.
