User Tips
- Cable Quality Matters: Always use high-quality, certified charging cables that are rated for the wattage you intend to use. Low-quality or incompatible cables can limit charging speed significantly (e.g., some cables may only support 18W charging).
- Check Device Protocols: If your device isn't fast charging, verify its specific charging protocol requirements. While this charger supports many common protocols, some proprietary technologies like Oppo/OnePlus VOOC/SuperVOOC may not be explicitly supported.
- Optimal Placement: Utilize the included U-shaped stand and 3M sticker to secure the charger on your desk. This not only keeps your workspace tidy but also ensures better airflow for heat dissipation.
- Avoid Overloading: When charging multiple devices, be mindful of the total output. The charger has a maximum combined output of 110W for multiple devices. Exceeding this can slow down charging for all connected devices.
- Normal Heat: It is normal for the charger to become warm during operation, especially when charging multiple devices or high-power devices. This is due to the energy conversion process.
