Review on ๐ก Get Accurate Battery and Charging System Readings with 12V Plug-in Tester with LCD Display by Jason Adams
This thing is AMAZING
Just plug this into your car's cigarette lighter and it will give you an instant battery voltage reading. The symbol also tells you whether the alternator is charging the battery. Ideal for quickly diagnosing your vehicle's electrical system. You can control and power up various electronics and see how the output voltage of your alternator changes. I like to ride and look at it at different RPMs and see how the voltage changes. This is not easily possible with a multimeter while driving! 3 colored LEDs light up according to the voltage display. I love the simplicity of this device.
