The Huawei GT2 Pro ECG watch can be charged via USB, but it cannot be charged using a phone. The charger included with the watch requires a USB-A port for charging. It is recommended to use the original charger to charge and follow the charging recommendations in the instruction manual to ensure the watch battery life and healthy use. During charging, it is recommended not to use the watch to avoid damage to the charger or other safety issues.
1. You can't charge your phone. 2. Because the Huawei GT2 Pro ECG smartwatch is charged through a magnetic charging stand, rather than charging through a mobile phone. 3. Mobile phone charging and smart watch charging are two independent systems, and there is no direct charging connection between them.
Therefore, the Huawei GT2 Pro ECG smartwatch cannot be charged using the mobile phone.
It's okay. As long as there is a reverse charging function of the mobile phone can charge you this watch. It actually means turning your phone into a power bank.
