Moto Z USB Type C to Aux 3.5mm Headphone Jack Audio Adapter & Charger 2 in 1 with [90 Degree Right Angle] Connector for Motorola Moto Z,Huawei Mate 10 Pro,Xiaomi 6,LeEco Le 2(Not for HTC and Pixel)

There's not much out there for P20 Pro. I haven't found an adapter that provides 3.5mm sound output and Supercharging.I will still give this item 5 stars. It never claimed to do Supercharging. I honestly didn't think it would charge at all, but it does. The music output is great. One thing I like is that the 3.5mm female connection is very secure, so there's no static from the cable. It also clips into the USB-C port solidly and the right angle connector is great.Until Huawei or someone else comes up with a Supercharger with 3.5mm sound, this is the best way to go.

I bought 4 different adapters and this one is the only that worked for my phone and my car sadly but it's very effective

This item did not do one single thing it advertised. It did not charge, it did not play music through the aux plug, it did not do either function together or individually. Maybe I got a bad seed, who knows. Got screwed on this buy.

I purchased for my Galaxy S9+. When I plug into charger and phone a notification pops up that I need to make sure to use charger that came with the phone. It also says my battery is dying fast than it can charge. I tried using the auxiliary port but couldn't get sound.

This is a 3 way plug. We use it on the motorcycle. To listen to music and to keep the phone charged up.

I tested it on my Motorola Moto Z and Huawei Mate 10, it works great on these two phones.
