Of all the adapters for Note 9 tested, this is the best advantage; light, small, works without a power source. This requires power for your phone and an external monitor, but it will work. Cons: The USB cable for the phone is very small. I had to take an extension cord, otherwise it's very tight. I wish this wire was a little longer. Otherwise, I definitely recommend this adapter for Note 9. Cons:
