USB Voltage/Amps Power Meter - 3pcs Pack

Product Description The USB Power Current Voltage Tester is designed for measuring voltage and current with ease. This multifunctional tester allows you to plug in your phone or other devices and directly read the voltage and current parameters. It also provides the capability to test the quality of your MicroUSB cable and battery capacity.

When testing MicroUSB cable quality, simply plug your phone and other devices into the 5V USB adapter plug tester and take note of the voltage. Then, connect the MicroUSB cable to the 5V tester plug and take note of the voltage again. The smaller the voltage difference, the better the quality of the MicroUSB cable.

To test battery capacity, use the TP4056 linear charging circuit to charge an empty battery fully through this capacity meter. The tester will give you the readings of the battery capacity, and it can also measure cell phone charging capacity and efficiency.

This USB Power Meter features data clearing and viewing capabilities for easy use. Hold down the button until the group of data moves to the next group, then release the button to automatically jump to the next set of data. For data viewing, simply double-click the button to enter view data mode. The backlight LED will blink, and then you can press the button to display the next set of data. Double-click the button again to exit the data view mode, with the backlight LED staying on.

The specifications of this USB Power Current Voltage Tester include an input voltage range of 3V-15V, load current range of 0.05A-3.5A, and a monitor charge capacity of 0-19999mAh. It has an accuracy of ±1% and a memory capacity of 10 sets of data. The package includes 3 USB Power Current Voltage Testers.

This multifunctional tester is designed with intelligent memory charging capacity data, monitoring and memory measurement data, and can store up to 10 sets of measurement data. The high voltage or low voltage will prompt an alarm, with the LCD screen arrow and the backlight LED flashing. Pressing the button will keep the LED screen lit for 30 seconds.
