Re: Need help finding a sub-100 dollar reciever
The USB spec for general use is 900 mA maximum, 5A for charging devices. Head units generally don't go over 1A as it's a safety hazard with the risk of melting the connection. It's not designed to keep up with constant use of the device. You may need to use a 3.5 mm stereo aux cable or Bluetooth and charge the phone separately.
