• As the power supply in the family is generally about 100v-240v (alternating current, referred to as AC), car and aircraft power supply is generally about 12V (direct current, referred to as DC), but these three commonly used power supply is unstable, can not be directly charged to the laptop, otherwise it will damage the battery and laptop.
