Agreed. Sudio Bluetooth headphones support fast charge function, you can use the fast charge head to charge. The output voltage and current of the fast charging head should meet the charging requirements of the headset, otherwise it may lead to poor charging effect or damage the headset. It is recommended to use the official recommended charger or choose a reliable quality brand when buying a fast charger. At the same time, be careful not to overcharge for a long time, so as not to affect the battery life.
No problem at all, the fast charge automatically determines the output voltage of the device being charged, and the Bluetooth headset will only be charged normally.
