    A fast and quick way of finding out battery charge/charging voltage and cranking voltage. Only to one decimal place but perfectly adequate for the application.

    I purchased this item for car battery checking for a friend who wants to be sure the car will have enough charge to start the next day. Contrast is not amazing (It could use a better screen), and sampling stare is not very fast, but seems sturdy enough.

    To monitor battery condition and charge rate of alternator. Early warning of battery losing charge too quickly before it becomes an issue on a cold and wet morning, never happens on a bright sunny day. Good value for money rather than caught and stuck with a non moving car. If you like gadgets and don't like being caught out with a flat battery it is good value for the money.

    Получил посылку за 30 дней.Упаковка хорошая.Вольтметры очень качественные.Раньше брал в другом магазине, но сдесь дешевле.Спасибо магазину.Цена очень хорошая.Показывает напряжение точно.Я сверял с хорошим стрелочным вольтметром.Погрешнось 0,1 вольта.Кому надо, советую брать . Очень хорошо контролировать подзарядку аккумулятора в автомобиле.Должно быть в пределах 13,6-14.2 вольта при работающем двигателе.Сразу видно как работает реле-регулятор.В этом магазине самая низкая цена на этот прибор.

    I have been using this mini LCD voltmeter on my motor bike and it works as a charm. It has already proved itself useful as while I was on a highway I noticed some ups and downs of voltage and it turned out to be a battery failure. So, as I was saying, very good for its money and very useful. Very easy to install (especially to a car) and very well made. Only cons are that it's not easy to read in excessive sunlight and the fact that it's not "fast" enough to follow the full voltage instabilities as an analog one would probably could.

    Недорогое,но очень удобное приспособление для контроля бортовой сети автомобиля.Измеряет напряжение с точностью до десятых долей вольта. Позволяет отследить скачки и провалы напряжения,а по напряжению судить о состоянии проводки автомобиля и степени зарядки аккумулятора.

    I honestly think that every car owner should have one of these units. • Clear large display is very easy to read • No mess and hassle free installation. Plugs into your cigarette lighter socket. • Very fast refresh rate • Displays the true reading of the voltage output even whilst driving. This means you can troubleshoot problems with the alternator or battery contacts A multimeter only shows the voltage of the battery whilst this LCD cigarette lighter shows the true voltage output. This is specifically useful in cases where the battery terminals are not tight enough. You would pick up this condition if you get wild voltage fluctuations whilst driving. When you rev the car the voltage would go up, and vice-versa. This means that the terminals are not making good contact with the battery. Some cars have the cigarette lighter powered even when the ignition is off. In this case make sure to remove the Voltmeter Monitor when car is not in use as it could drain your battery if left for a long time. Bottom line: The cheap price and precise voltage reading makes this a must buy, and a best buy! Highly recommended
