USB Tester Multifunctional Power Off Save Function Digital LCD Display Voltage Current Security Meter

Feature: 1. Real Time Monitoring: Voltage, current and capacity are displayed on the same LCD screen, no cumbersome operation is required, just connect the USB interface, you can monitor the charging status of the phone in real time. 2. Supporting Protocols: It supports multiple protocols such as QC2.0 and QC3.0, supports screen rotation, and can read at any angle. 3. Power Off Save Function: Contains 9 groups of power off save functions, which temporarily store the current capacity and energy when the power is off. 4. Remove Manually: Reopen the opportunity to accumulate the currently used capacity and energy, if it does not need to accumulate, remove it manually. 5. Intelligent Memory Charging Capacity: Can save the mAH input of 9 groups of charging equipment after power off. Convenient to view and check whether the capacitance of the charging device is real.
