Wireless charging of 15 watts is not fast, because it has a charging current of 3A and a charging current of 25 watts is 5A. The same mobile phone for 400N battery, pigeon charging time is not the same, with the power of 15 watts to charge more than an hour ah, if the use of 25 watts charge only takes more than 40 minutes, this is the difference between fast charge and general charger. However, we must pay attention to the use of the original charging head and charging cable to support fast charging.
doesn't count
Not fast charge. Wireless charger refers to a charger that does not need to be connected to the terminal device that needs to be charged with the traditional charging power cord. It uses the latest wireless charging technology, by using the alternating magnetic field generated between the coils, the transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment.
Not fast charge, 15W fast charge provides 3A charging current, 25W fast charge provides 5A charging current, when two chargers at the same time to charge 4000mA battery capacity of the mobile phone, 15W fast charge takes 1 hour and 20 minutes, 25W fast charge takes 48 minutes.
