This is Ben from ChargerLAB.
We actually have the 27W GaN Anker USB-C charger in our hands for months. But my boss won't let me tear it down as it is the only one we have and there are some testings need to be done before we destroy it.
We might dissemble the RAVPower 45W GaN USB-C charger next week though. I probably don't have the calibre to give a detailed explanation, but at least you guys will be able to see what it looks like inside from photos.
