A stabilization apparatus for stabling load voltage of vehicle is applied to a vehicle battery unit, a vehicle computer unit and a vehicle load unit. The stabilization apparatus for stabling load voltage of vehicle includes a voltage boost unit and a microcontroller unit. The voltage boost unit is electrically connected to the vehicle battery unit and the vehicle load unit. The microcontroller unit is electrically connected to the voltage boost unit and the vehicle computer unit. When the voltage of the vehicle battery unit is going to drop, a voltage-drop signal is sent from the vehicle computer unit to the microcontroller unit. The voltage boost unit is controlled by the microcontroller unit to supply a boosted voltage to the vehicle load unit.
