Fast Charge injection AndroidAuto/CarPlay

Applications

• Enable fast charging for your phone while using Android Auto and CarPlay. Reduce charge time and phone temperature. Require the user to have a car charger that supports USB-C to USB-C Power Delivery. If your charger has USB-C output, it should support Power Delivery (PD).
• Allow power down for AAWireless with a USB port with always-on functionality. Splitting the power supply to a normal USB port that will turn off with your car, while allowing data to pass through from AAWireless to your head-unit. Require your AAWireless to have a USB-C connector.

Note: Using 1ft cable from the charger to the adapter board will give you the best aesthetic and ease of cable management. From the adapter USB-C out, any good quality cable less than 10 feet will work. You can get the 25cm (10") red cable from the demo.

Frequently asked questions

Will it work on iPhone 15/16/+ with USB-C?

Through other user tests and support, the USB-C iPhone will work, but require some additional connection. You will need:

• Apple USB-C to Lightning cable(C91) or 3rd-party MFi-certified USB-C to Lightning cable (C94).
• Apple USB-C to Lightning adapter

It is important to use a genuine adapter. 3rd party adapter will not provide a good charging rate.

Which AndroidAuto wireless adapter will work?

We have had positive reports on AAWireless, which has a USB-C input. No USB-A wireless adapter has been tested or reported working by our customers. There should be no other USB-C adapter in between, but only the fast charger adapter here.

Why I got slow charge or no charge at all

Try to rotate one of the USB-C heads 180 degrees at the adapter. Also, make sure that you are using USB-C to USB-C for all cables. USB-A will not work in this application.
