Yes, the wireless charging of Huawei glasses must use a special glasses case. Because Huawei glasses cannot be charged separately, you can only charge them by placing them in the matching glasses case. This is designed with convenience and safety in mind. Specifically, the glasses case is equipped with a charging coil and a battery, so that it can be used as a charging device while storing the glasses. In addition, the charging method of Huawei glasses is achieved through NFC contactless wireless charging technology, so you can only start charging the glasses by putting them into the glasses case. Please note that this charging method does not support QI wireless charging devices, such as mobile phone wireless charging base, bracket, mobile phone or tablet reverse wireless charging.
