Nice little tester and cheap to check any device that charges via USB and see if the charger or power bank provides the correct voltage and current and how much. 5V is the standard voltage of the USB port, (first photo, charging 21700 batteries in a charger that supports max 2A) but if the device being charged (e.g. mobile phone) and of course the charger support QC3, it will show a voltage above 5V. Usually, you will see around 9V/2A or even more depending on the wattage of the charger (second photo, charging mobile phone with QC3).
Translated from Greek ·Did you find this review helpful?Quite a good tool. Helped with a faulty mobile phone that appeared to be charging but actually wasn't drawing any current. I was also able to measure the performance of my solar cell under various lighting conditions.
Translated from Greek ·Did you find this review helpful?Where good and economical product.
It can also display the 9 V voltage but I don't think it can measure the load.
It is mainly for loads in USB 5 V.Translated from Greek ·Did you find this review helpful?Verified purchase
Simple and easy to use
