Please read the following information carefully before purchasing:

1. Please ensure your phone supports wireless charging.
2. Incompatibility case: If your phone case thickness is ≥4mm (0.16 in), or uses an OtterBox case (too thick), it may cause overheating or other anomalies during charging.
3. For leather cases, as they do not dissipate heat well, it is normal that the surface temperature of the phone during charging is higher than with silicone or transparent cases.
4. When attaching the wireless charger suction cup to the dashboard, make sure to choose a flat area and press the suction cup tightly before locking it. Wait 30 minutes after installation before placing the phone on it for better adhesion and to prevent falling off.
5. If the arm clamp occasionally cannot secure the phone, it's probably due to the phone being placed at an angle. Adjusting the phone's position should resolve this.
6. If your phone's rear camera is against the charger surface and it doesn't charge or charges intermittently, it indicates that the wireless charger may not be compatible with your phone. Should you require more information, we are available.
7. If the charging speed is slower than expected when using the wireless charger in a car, it could be due to high in-car temperatures and running map or music apps simultaneously. The charging power will prioritize the phone's motherboard, with only a small part going to the battery. Once the in-car temperature drops to ≤26℃ (78.8℉), overall charging power will increase, improving the battery charging speed.
8. Please note, a QC3.0 car charger is needed as the device's power source (to be purchased separately).
