Slow Charge

Fast-charging mode can only be activated when the car charger, cable, and device meet the same fast-charging protocol.

Our car charger supports QC (Quick Charge) and PD (Power Delivery) protocols, which work well with most devices that support these standards. However, some brand like Huawei, Oppo, Vivo, and Honor uses a proprietary charging protocol that is different from QC and PD. As a result, our adapter cannot take advantage of the car charger's and phone's maximum fast charging capabilities.

Here are some troubleshooting tips that may help identify and resolve the problem:
1. Try another cable, out port, and phone/device.
2. Check if the charging port is physically damaged or loose.
