My car suddenly didn’t start 1 day and then started fine the next day. I bought this to figure out if the problem was the battery, starter or alternator. Once I got this I plugged it in and saw the voltage reading. I bought and installed a new battery and voltage reading are good now. I read if the voltage is less than 12 with the key in and car not running indicates a bad battery. When the car is running voltage of less than 13.4 indicates a bad alternator.

I purchased this primarily to monitor the health of my Auto battery and charging system. I also find it informative to monitor the charge rate of my mobile phone and other USB charged electronic devices.
