D1Spec voltage stabilizer with Red display DS-IN-005

The D1Spec voltage stabilizer extends the life of the battery and the alternator improves the efficiency of all electrical devices in the car improves the power of the ignition spark prevents fluctuations in speed when the current is suddenly consumed (e.g. when the fan is switched on) increases the power of the car Has a hood opening sensor (similar to alarms), When closed, the display LEDs turn off. Made in Japan.
