Belkin Rockstar 3.5mm Audio + USB-C Charge Adapter - Black (NPA004btBK) is rated 4.1 out of 5 by 72.
Rated 5 out of 5 by from Will NOT transfer DATA - and that's a GOOD thing! Works well, but the best thing about it is that the USB port will NOT xfer DATA, will NOT SYNC, and CANNOT be used for Backing Up the phone. It ONLY charges the battery. It is for POWER ONLY -- not DATA. When I plug it into my computer, the computer does not recognize the phone as a "connected device". (Also verified on the Belkin Website). And that is a GOOD THING - read on. Why is that a GOOD thing? Well, now I don't have to worry about using a charging port at the airport, cafe, or other place where the "free" charging port may have been HACKED to access the data on my phone while I use the "free charger". One less thing to worry about!!!!

Rated 1 out of 5 by from Buyers beware It stoped working on the aux side, 2 months in. You can get a replacement but you have to pay for shipping to return the old one, what’s the point when it broke from a manufacturer standpoint. If I broke it, I get it,

Rated 5 out of 5 by from Does the job! [This review was collected as part of a promotion.] I got this to replace a simple usb-c to headphone adapter I have been using since I damaged my 3.5 mm headphone jack on my phone. I don't use it a lot but it comes in very handy when I need it. I have two vehicles without bluetooth and I prefer just to use a wired connection. This lets me charge my phone and use headphones or the auxiliary input in my car at the same time. The sound is clean when it is charging and without any interference. I also like that it is small and simple and does exactly what I need it to.

Rated 1 out of 5 by from Bad product Trash. I’ve been through 3 of these and they stop working on the aux side. Each one lasts about 3-4 months. Don’t waste your money.

Rated 2 out of 5 by from Not usable when charging port is plugged in [This review was collected as part of a promotion.] The adapter works ok with our Pixel 6 as long as the charging port is not used. Plugging in the charging port creates a lot of noise, so it is not usable to play and charge at the same time. After failing with this adapter I bought a Bluetooth to audio adapter and it works much better and was much less expensive.

Rated 5 out of 5 by from Love the duel use of this adapter [This review was collected as part of a promotion.] I love this! As you know Android phones are getting rid of aux ports which frustrated a lot of people. But I'm glad adapters were made you can place in your charging port. But then that usually takes up the option to charge your phone at the same. So if you want to listen to music for an extended period time, you'd be draining a lot of battery. But not no more with this amazing Adapter that let's you charge your phone and listen to music via an audio cable! It works flawlessly, gives fast charging and it's pretty self explanatory on how to use it.
