Frustrated by your wireless Android Auto or CarPlay adapter staying powered on after you’ve turned off the car because the USB port is always on?

Fortunately, there’s a simple solution!

Our custom-designed magic cable ensures that the adapter powers off when your car does. Enjoy a truly seamless wireless experience!

Where to buy the Magic Cable

How it works:
  • The connector #1 (black plastic tongue) of the cable goes into charging (power only) port (might require USB car charger or USB-A to USB-C adapter, see examples below)
  • The connector #2 (white plastic tongue) of the cable goes into your car's "smart" USB port (the one for wired Android Auto or CarPlay)
  • Plug your wireless adapter into port #3
This solution is using the fact that this "always-on" behavior is only limited to the "data" USB port. All the other types of USB ports and 12V cigarette lighter ports turn off when the car is off. As easy as that! And the best part is, it’s compatible with any wireless adapter out there.
Cars known to have this issue:
  • Kia Niro
  • Kia Niro EV
  • Kia EV6
  • Kia Sportage
  • Hyundai Ioniq 5
  • Hyundai Ioniq 6
  • Hyundai Sonata

Please note, that depending on your car and the position and/or availability of the additional USB port, you may need one of the following:
  • USB car charger (plugs into a 12V outlet; widely available at dollar stores or you can get it using the links below)
  • USB-A to USB-C adapter (included with most wireless Android Auto/CarPlay adapters; otherwise, available at dollar stores or you can get it using the links below)
Not sure what this is all about? We're happy to explain!

Android Auto and CarPlay seamlessly integrate your phone with your car’s infotainment system, providing easy access to navigation, calls, messages, and music. They are available in both wired and wireless options—wired connections offer a stable link, while wireless allows for a clutter-free experience without plugging in your phone every time you drive.

Cars that only support wired Android Auto or CarPlay can be easily 'converted' to wireless. To enable wireless connectivity, various adapters are available, offering a seamless, cable-free experience without sacrificing any functionality. Simply plug the adapter into your car’s USB port, pair your phone via Bluetooth/Wi-Fi, and enjoy an effortless connection every time you drive.

However, some car models keep their 'smart' USB ports powered even when the car is off. This can cause issues with wireless Android Auto / CarPlay adapters, as your phone stays connected to the adapter even after you've left the car. As a result, you may experience the following:

  • Wasted Mobile Data: Your phone can't switch to your home Wi-Fi and keeps using mobile data.
  • Audio Confusion: Your phone tries to connect to your car’s Bluetooth for calls and media playback—even when you’re not in the car.
  • Power Drain: The wireless adapter continues to drain power from your car’s battery, even when not in use.
That is why you need our Magic Cable which blocks the power to the adapter when the car is off.
