Perfect adapter

I love the adapter. Both OTG and charging functions work well. It keeps my old iphone being charged, making it a dedicated apple music player. The charging port is limited to 5v 2.5A USB charger. High current USB-C charger like the ones for ipad won't work.

music works great, charger port doesn't work at all

My feelings about this are a mixed bag. Build quality is nice, and music comes though nice and clear. But the whole point of this pro-version is to have a functioning charging port. :/
