Regarding this issue, as far as I know, vivo wireless audio and video headset HP2154 does not support flash charging function. Flash charges are often used to quickly charge smart devices, while wireless headphones are usually charged using a charging case, which can charge more slowly. If you need a quick charge, it is recommended to use a charger with a flash charge function to charge your headphones.
Not supported. Although the official publicity has words such as speed flash charge, in fact, you can see the battery capacity, this thing has a low battery capacity, the charger is still 5V 260MA, charging quickly
