Integrated Voltmeter: It’s not always the battery jump starters fault. There is a myriad of reasons why your car won’t start (e.g. starter problems, worn-out battery cables). But with a built-in digital voltmeter, you can quickly determine if it’s a discharged battery or something else. If the voltmeter shows a good battery at 12.7-12.8 volts, it is most likely another problem.
