By simply inserting into the cigarette lighter socket, you can not only improve the performance of electronic devices by supplying a stable source of voltage, but it is also possible to check the current status visa the voltage meter.
 • Voltage Stability Improve Car Performance 
 • Improve ENgine Torque 
 • Improve Mileage/ Save Fuel 
 • Improve Audio Quality 
 • Improve Light Illinance

Checking Voltage Gives Protection from Performance Loss
 • Lower Voltage means Lower Quality Sound/ Unstable Operation for All Electronic Devices 
 • Low Battery Charge 
 • Battery Life
