Pros: Good display, solid build. I use it to measure different devices charging currents and it works well. Cons: Cannot use with wall chargers directly, must use additional extender cable. Must purchase separately.

I wanted to be able to check the voltage AND current of several USB devices that I won including mobile power banks, USB lights, and different USB cables. This allows me to test them all and see the real voltage and current they are using. Additioanlly, they allowed me to see which cables are me... I wanted to be able to check the voltage AND current of several USB devices that I won including mobile power banks, USB lights, and different USB cables. This allows me to test them all and see the real voltage and current they are using. Additioanlly, they allowed me to see which cables are more efficient than others allowing me to speed up charging time by picking the better cables. The onyl negative is that certain devices (some usb powered lights) did not like this in between the device and cable and so it didn't work - but more most thigns it worked fine. Read more

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: look like on picture , nice big digits nice final touch. cons: nothing special. for recommendation.

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.

Ideal to control charger battery.

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!
