Issues: the USB output is not properly designed, it causes RCD tripped in my use case. The viewsonic projector is connected to first socket and connected to a Google TV. As long as the Google TV USB power cable connected to the USB power port, it trips the RCD. This indicates the USB power is not properly designed, it is likely provide the current leakage path between earth to Neutral/Line and tripped the RCD protector. There is a small chance something wrong with my Viewsonic X10-4K projector or Google TV design, and caused the RCD tripped. The real reason is unclear to me.
