Conect the monitor to the USB of chargers, external batteries and smart phones,
read the current and voltage in the LED screen
Very Useful for iPhone, iPad, Android phones and Tablets
Monitor the charging status of android smat phones, tablets, iPad, iPhone, etc. , and display the charging current and voltage in real-time
Charger Doctor and Defective Device Detector
Measure the current and voltage output of wall chargers, car chargers, external batteries and PC, to identify whether the charger works or the
reason of charging slow
Small, Powerful and Easy to Use
Small, portable, powerful, easy to use. Measure precise voltage and current more easily, compared to large current and voltage meters
Wide Compatibility and Accurate Results
Wide compatibility and accurate results. Meet the testing needs of almost any USB charging devices
Bright red LED display, visible in the dark, and easy to read
Scope of work:Current(0A-3.3A),Voltage(3.5V-9V)
- 1,Monitor the charging status of smart phones. With this multimeter you can easily distinguish poor quality cables and chargers, and find out the reason why your phone charges slowly.
- 2,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.
- 3,Two-line dual-color display of both current and voltage. It is easy to distinguish and you can read both data at the same time.
- 4, 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 the same with both output(parallel circuit voltage is equal), and the current is the sum of the two ports.
- No battery, no on/off switch, plug and play
