Works great!
For USB C Splitter for Android Auto / Apple Carplay
I received the splitter today and got it hooked up. I can't verify the actual charging rate as I do not have a USB-C power meter but my phone reports that it is fast charging and it is absolutely charging *significantly* faster than it ever did when connected directly to my headunit. Whether I get *full* fast charge speed or not, my phone now charges quite quickly when connected to my car and with the screen on, whereas when connected directly to the headunit it would only tick up maybe a percentage every 30 minutes with the screen off and would discharge when using the phone as well.
This is with a S21 Ultra and an aftermarket Kenwood headunit.
Awesome product!
Edit: Review edited to reflect further time with the product. Initial impression left me unsure if I was getting full charging speed, without the ability to actually measure, further time has let me realize that it does, indeed, seem to be charging at full speed. My initial impressions seem to have been off due to my car not providing enough power to the 12v aux port for my charger when the engine was turned off. With the engine running, my rate of charge increased significantly.
As noted on the FB group, now I want one with the power source switchable between the AA and the charger so I can decide when I want a power boost and when I just want a trickle to let AA run! lol
