  What is the point using GaN in a 20W charger?

    The heat at 20W is a non-issue, but the efficiency is nice.

    I asked one of my friends who works in Shenzhen what the difference in BOM would be for a white label GaN vs. silicon-based 20W USB charger.

    What he said is that if you order in large volume, a 20W USB-C charger will be around $3, and using a GaN rather than silicon-based IC would be pretty much negligible (less than 50c). However, that many smaller charging bricks which are using GaN are potentially using rejected ICs or just trying to simplify the supply chain.
