Question Which aux-to-bluetooth adapter should I get?

[ICameon]

Which aux-to-bluetooth adapter should I grt? It is to connect my phone to, but it needs to be one that can be powered by being plugged into the aux port instead of recharging it. Here is an example of what I am talking about.

Seems you forgot to post the example, there is no link or image in the post.

I have not seen a aux to bluetooth adapter that did not need to be powered, they all have a batter and are charged through USB. I own a couple of TaoTronics models, like this https://www.amazon.com/TaoTronics-Bluetooth-Transmitter-Receiver-Simultaneously/dp/B01EHSX28M and they work very well with good audio quality. I own two of these ones, one is in my car, other I have for home use https://www.amazon.com/TaoTronics-B...nics+aptx&qid=1595558018&s=electronics&sr=1-5
