Please be aware that fast charging devices work with standard protocols such as PD, PPS, and QC, among others. Before buying, ensure to check the product details to confirm it matches your charging cable and device model. Avoid using it in wet, hot, or fire-prone areas.

1. A little increase in temperature while wirelessly charging is typical, particularly with intensive usage. The device's metallic construction improves heat dissipation for effective charging, which can lead to a warmer sensation.

2. When charging rapidly, experiencing heat is expected, so there's no need for concern; once it reaches a certain power level, it will automatically lower the temperature. If the receiving coil or the transmitting board gets too hot and charging halts while in use, please disconnect the charging device. After allowing it to cool, attempt to charge again.
