Why can not wireless headphones high voltage fast charge?

The battery usually used in wireless headphones is a polymer lithium battery or similar battery, which needs to be charged slowly, that is, we often say slow charge, to ensure safety. If the high voltage fast charge is used, due to the excessive current, the battery temperature may rise, the chemical reaction inside the battery is too fast, resulting in accelerated aging of the battery, reduced capacity, shortened life, and even cause the internal gas production and leakage of the electrolyte. Therefore, the use of high voltage fast charge can cause potential damage or risk to the battery and electronic components of the wireless headset.

At the same time, the power of the wireless headset is generally not very large, and the high voltage fast charge may not be able to increase the obvious time efficiency for its charging, so the use of slow charge to charge is more practical and safe for maintaining the stability of the device, charging safety and battery life.


Because using a high-power charger to charge the headset, it is easy to impact the battery of the Bluetooth headset and damage the battery of the headset. Headphones should be charged with a special charger, otherwise it is easy to break the battery of the Bluetooth headset.

Generally supported, although there is a fast charge protocol, the speed can reach 120w

But the headset has its own power management chip, will not really output 120w, will adjust it to the appropriate power charging.


The wireless headset battery capacity is small, the space is also small, the components used can not withstand the impact of large current.


The answer is no, there are two reasons, one is unsafe, because the Bluetooth headset battery capacity is small, high current charging is not safe, but also affect the battery life, personal recommendation charging current should not exceed 3 amps, do not charge for a long time.
