The protocol of non-Huawei mobile phone is not compatible, if it is a Huawei mobile phone, it also depends on whether it has the super fast charge function, depending on the charging head power, greater than or equal to 22.5 watts is supported. In order to make the charger more intelligent, Huawei added an IC chip in the fast charge, and this Huawei fast charge intelligent IC will monitor the current phone power in real time, and dynamically adjust the input current, to ensure that the charging process is not hot at low temperature, in line with the safe charging curve, so only the fast charge head and wire that support the super fast charge function can automatically open the super fast charge.
