The charging brick that comes with a charging brick, or recommended by Apple, usually won't provide the fastest charge for all Apple devices. However, it can be worth spending more money on a more powerful charger, as every Apple device has its own maximum charging rate. The M4 13-inch iPad Pro can charge at up to 35 watts, and switching to a higher charger can double this speed. The power of the charger, the 0 to 50% charging time for the supplied charger, and the 0.50% charging rate for the optimal charger can be determined by the manufacturer. The article also addresses concerns about the potential stress of the battery, as Apple's built-in battery management adjusts the power draw to suit the battery.
