What's the difference between power AC and DC?
AC generally refers to the power supply between the voltage into AC 220~250V, generally only do household appliances into the industrial production line, and the commonly used 380V (DC volts) refers to the DC power supply, commonly used are 3.0V, 6.0V, 9.0V, 12V and several other common voltage,
AC is alternating current, DC is direct current
Batteries and chargers are the most typical, but the average charger output is about 4.5V, universal charging more pressure value!
