10V4A fast charge technology, that is, 10V voltage and 4A current fast charging method. According to the power calculation formula P=VI, it can be seen that the fast charge power of 10V4A is 40W. This means that the charger can quickly charge the device with 40W power in the working state, and the 10V4A fast charge can charge the device faster, improve charging efficiency and save charging time compared to the ordinary 5V2A charger. Therefore, 10V4A fast charge is a high-power, high-efficiency charging technology that is suitable for devices that require fast charging, such as smartphones, tablets and laptops.
Power = Voltage x current =10v x 4a=40w fast charge
