1、LCD digital display, simple and visual display power supply output voltage, current 4-bit high-accuracy simultaneous display. 2、Independent 5V2AUSB charging, with current detection. 3、A multi-purpose independent 9V power supply hole, can provide multi-meter and other power sources to achieve a multi-function use. 4、2A pointer display (LCD display and pointer display at the same time), continuous power pointer strap LED light illumination operation is more convenient and clear. 5、There is a temperature sensing device inside. The cooling fan works only when the temperature exceeds 45 degrees, and it does not work when it is low in power consumption, reducing noise. 6、The machine is equipped with an overload fuse. When the machine is inadvertently overloaded, the fuse starts to protect the machine from overloading.
