Price in title inclusive of GST.
Here is a very cheap USB C to HDMI adapter. These are normally quite expensive
Please note!!!
From what I have read for similar adapters, you will need to use the genuine Nintendo 15v charger otherwise the Switch battery will slowly deplete while playing.
I have ordered one for ~$12AU including shipping, and hoping for the best.
