    Excellent product, exceeded my expectations, I recommend to all your purchase, congratulations Team Banggood,very precise small item, very useful because you can measure during you're using the usb hub. It can be useful for searching moments when current disrupts, too but i not yet had tu use it for that use .

    Muy buen tester permite saber el voltaje y corriente en tiempo real que se está consumiendo. También permite evaluar si es conveniente colocar un dispositivo o no acorde el voltaje.

    Very useful for measuring power bank capacity. Also for diagnosing charging issues on phones and some USB cables (for example: phone charges slowly) Good idea to use a quality USB A male - female extension cable plugged to the output of the wall charger, and a short cable to the output of this device, to the device under test, that way is easier to read Also remembers charging time and capacity (mAh) when unplugged, you can reset by holding the button for few seconds One of the best in features

    This thing is doing its job. For some reason the screen is monochrome, not color as shown in the images. But that's not an issue.

    Great little product to se how fast a cable can recharge your devices and how long time it takes. You can even use it to keep track of how much mah capacity a power bank really has! It has two display modes/pages
