The ZKETCHE EBD-USB Voltage and Current Monitor is a DC electronic load with a USB interface, designed for testing power banks and chargers. It supports charging voltage trigger detection as well as USB charging voltage and current detection compliant with QC and MTK protocols. To accurately display relevant test information, the device must be used in conjunction with a dedicated software application called "EB Software." This software supports features such as curve plotting and device firmware upgrades. Two modes are available in the software: Constant Current Mode and Ammeter Mode. Constant Current Mode: Connect the male USB to a charger/power bank, then activate "Constant Current" mode to perform constant current discharge testing of capacity or current output performance. Ammeter Mode: Connect the male USB to a charger/power bank, connect the female port to a device via a charging cable, then activate "Ammeter" mode to record the charging curve from the male to the female port. In addition, "Ammeter" mode is also used for testing D+/D- voltage and MFI current.
