Does the Power Adapter Extension Cable work with the newer 70W USB-C Chargers?

Hi everyone here.

Main concern is dimensions / shape of the Power Adapter "Head"- the part where the extension cable connects to the main body holding the charge electronics.

Considering buying this for the 70W charger as I'm fairly annoyed with the "tingling" as a result of the doubly isolated power supply implementation of the 70W USB-C charger.... Need the earthing pin implementation that comes with the Power Adapter Extension Cable....
