    First off, I ordered this and upon arrival, it went up in smoke. Sadly, the first one was defective. But, on the upside DX has great service. Sent an e-mail with a photo and within a few days a replacement was on its way. Very little hassle, and very happy with the service. As for the meter, not... Read more

    It has been really useful for me beacuase I wanted to test mi phone charger and several usb cables that I have at home. I have been able to test their quality and, for further purchases, buy only those who guarantee an amount of A that allows to charge my phone in a reasonable time.

    Tells you the voltage and current with very good accuracy (tested with another device). Easy to carry and allows usage of the USB port while monitoring.

    Заказываю уже не в первый раз. Очень доволен!!! Полезный девайс для проверки как напряжения, так и тока, причём Напряжение можно замерять как под нагрузкой, так и без нагрузки. Максимальный ток, который мне удалось увидет это 1,6А. Если гарят флэхи и тому подобной, то думаю для проверки питания... Read more

    Useful if you want to connect more stuff to a router, cable modem, etc embedded/low power device. Thought I was running out of USB ports, but thanks to this meter found out how many non-powered USB devices could be connected to each port with a USB hub, for example two 2.5 HDD's and a USB fan,...
