Be the first to review this product

Quick Overview

Monitor the charging status of android smart phones, tablets, iPad, iPhone, etc. With this detector you can easily distinguish poor quality cables and chargers, and find out the reason why your phone charges slowly.

Accurately measure the voltage and current of a USB power supply, but it's smaller, more portable and more convenient than a big and expensive multimeter.

Two-line dual-color display of both current and voltage. Voltage displays in red and current displays in blue, it is easy to distinguish and you can read both data at the same time.

With a cable connected to the input plug, the detector can fit chargers and power banks of any shapes and directions. It is more convenient than other fixed designs, because it is easier to connect and read the data.

Two output ports make it possible to charge two devices at the same time with one charger. But please be noted: if you connect 2 devices to the detector, the voltage is of both output(parallel circuit voltage is equal), and the current is the sum of the two ports.
