    A great product with many uses, only 1 con, the usb connectors are 90 degrees so it can give trouble on some adapters, see pik, other than that its a must have for gadget geeks, would recommend SKU: 311033 instead

    Pros: Shows you the real output of your charger. Cons: Its reading intervals are a bit too fast. The numbers keep changing. But you get an idea of how your charger works.

    вещица занятная - проверил все свои зарядки и пришёл к выводу, что нужно пользоваться родными гаджетами, "китайские" зарядки уж очень большой разброс дают (моя нокия кстати сразу предупреждала :) вот такой китайский "предатель" своих же закладывает ;)

    Pros: Simple to use, functional and well-priced Cons: USB input socket is a bit tight. Display values fluctuate but if you wait you can tell what the average values are. General: Easy to use and does what it says. Recommended

    Fantastic little tool, helps to have a look at your devices' power consumption while charging, let's you check if your charger is supplying the current it should.

    Очень удобно измерять напряжение и ток различных USB-зарядных. Как только получил сразу же измерил все возможные комбинации зарядных и кабелей. Узнал для себя много нового. С помощью этого девайса можно подобрать наилучшие зарядные устройства для своих гаджетов!
