The reason for the slow charging speed of Huawei 88W charger depends on the device and charging environment. If the connected device does not support 88W fast charging, the charger will be charged according to the device's compatible charging standard. In addition, environmental factors such as too high or too low a temperature, poor cable quality, or poor contact with the charging head can also affect the charging speed.
Ensure that the device supports 88W fast charging, use original cables, and place the charger in the appropriate temperature range to improve charging efficiency.
