USB3.0 USB Meter Tester (UM34C)

Product Description Unique Setting Page allows you to set the display to your liking and adjust the Screen Off time and Brightness.

Multiple Ports include a USB-C input and Micro USB port, allowing you to use these ports to test the resistance of a cable. For testing current, simply use the USB-A in and USB-A out ports to check the voltage and current.

Protection Film is included on our USB meter, offering added durability and protection.

Works with USB Load HD35, allowing you to use certain voltage and current to discharge the charger or power bank, and view data on the USB meter to check performance.

Identify fast charge protocols, such as QC2.0/QC3.0, Apple 2.4A/2.1A/1A/0.5A, Android DCP, and SAMSUNG protocol, by checking the D+ and D- voltage at the identification page.

Communication Version UM34C features APP control, while UM34 is the non-communication version without APP control.

Use the USB meter correctly by using USB-A to USB-A. Note that the structure of the ports are different and cannot work from USB-C to USB-A.

Suitable for many devices, this USB meter is compatible with chargers, electric loads, power banks, and more, allowing you to clearly view the charging voltage and current.
