If your device is not charging with the 72W Type-C PD Car Charger Adapter (ST-TCPDCCS, ST-TCPDCCM), check the blue LED first, because it lights up only when the charger is properly connected to your vehicle's power outlet. The 72W Type-C PD Car Charger Adapter delivers up to 60W from its USB-C Power Delivery (PD) port and up to 12W from its USB-A port, and no charging cable is included in the box.

How to fix charging problems with the 72W Type-C PD Car Charger Adapter

1. Push the charger firmly into your car's 12V power outlet, sometimes called the cigarette lighter socket, and look for the blue LED. The LED illuminates to indicate a proper connection.
2. Start your vehicle or turn the ignition to accessory. Many cars only power the outlet when the ignition is on.
3. Try a different power outlet in the vehicle if you have one, since a blown fuse on one socket is common.
4. Swap your charging cable. Cables are not included with the 72W Type-C PD Car Charger Adapter, and a worn or low quality cable is the most common reason a device will not charge.
5. Match the cable to the port. Use a USB-C cable on the USB-C Power Delivery (PD) port, which delivers up to 60W, and a USB-A cable on the USB-A port, which delivers up to 12W.
6. Move your device to the other port to see whether the problem follows the device or stays with the port.
7. Charge one device at a time. Both ports work together, but they share the 72W total output.
8. Check the socket and the connectors for debris, and reseat the charger.
9. Test a different device on the same port to work out whether the issue is the charger or the device.
10. Set the right expectation on speed. The 72W Type-C PD Car Charger Adapter does not support the Quick Charge (QC) protocol, so a QC device charges at regular speed. It works with both Power Delivery (PD) and non-PD devices and adjusts voltage and current automatically.
11. If you are charging a laptop, check its power needs. The USB-C port supports Power Delivery profiles up to 20V and 3A for 60W, so a laptop that needs more than 60W may charge slowly or only while idle.
12. Unplug the charger when you are finished if your vehicle keeps the outlet powered after the engine is off, which helps avoid draining the car battery.
