"The T1R V-Power Voltage Stabilizer regulates the voltage of the car's electrical system, providing constant voltage at all times. Normally the electrical system's voltage will fluctuate under acceleration resulting in power loss and rough power delivery. The Voltage Stabilizer eliminates this voltage fluctuation, providing a constant voltage, thereby smoothening power delivery and optimizing power. Low rpm performance is improved noticeably, with improved response, acceleration, and smoothness. Fuel economy is also improved, especially for city driving conditions. This product also features a ON/OFF switch for safer installations. Avialble in 4 colours i.e. red, blue , silver & gold."
