If your device is not charging with the 30W Dual-Port Wall Charger (ST-MCCAM), the cause is usually the cable, the port you are using, or a device that needs more power than this charger provides. The 30W Dual-Port Wall Charger delivers up to 18W from its USB-C Power Delivery (PD) port and up to 12W from its USB-A port, for up to 30W total, and no charging cable is included in the box.

How to fix charging problems with the 30W Dual-Port Wall Charger

1. Plug the 30W Dual-Port Wall Charger directly into a wall outlet, then look at the LED indicator on the charger. The LED lights up when the charger is in use.
2. Try a different wall outlet to rule out a dead outlet or a power strip that is switched off.
3. Swap your charging cable. Charging cables are sold separately with the 30W Dual-Port Wall Charger, and a worn or low quality cable is the most common reason a device will not charge. Use an original or certified cable for the fastest, safest charge.
4. Match the cable to the port. For the USB-C Power Delivery (PD) port, use a USB-C cable rated for at least 18W Power Delivery. For the USB-A port, use a standard USB-A cable that matches your device, such as USB-A to USB-C or USB-A to Lightning.
5. Use the right port for the device. Connect USB-C phones and tablets to the USB-C Power Delivery (PD) port, which delivers up to 18W. Use the USB-A port, which delivers up to 12W, for a second phone, a power bank, Bluetooth earphones, or another USB powered device.
6. Charge one device at a time. Both ports work at the same time, but the two ports share the 30W total output, so a single device charges best on its own.
7. Confirm your device is supported. The 30W Dual-Port Wall Charger does not support the Samsung Galaxy S20.
8. If you are traveling, check the outlet shape. The 30W Dual-Port Wall Charger accepts 100V to 240V input, so it works with most power systems, but the plug is built for one region. In a country with a different outlet you need a plug adapter that matches your destination. A plug adapter only changes the shape of the plug.
9. Set the right expectation for laptops. The 30W Dual-Port Wall Charger is best suited to smartphones and tablets rather than power hungry laptops. If you need to charge a laptop or charge several devices at full speed at once, a higher wattage charger is the better fit.
