USB C Power Meter, 360° Rotating HD Color Screen

【Comprehensive Detection】This USB tester instantly identifies PD3.2, PPS, QC3.0, SCP, SuperVOOC, and other fast charging standards. With a 0-12A range, it verifies the actual charging performance of any phone, laptop, or power bank.
【Professional Accuracy】Equipped with a 0.001R sampling resistor and software calibration, this bidirectional ammeter provides stable and validated readings. The zeroing function eliminates the 0.01-0.02A no-load current for accurate low-power measurements.
【360° Rotating Display】The 0.96-inch HD color screen rotates in four directions, allowing you to monitor voltage, current, and capacity from 0 to 99999mAh from any angle. A long press toggles between the vibrant color mode and the classic black and white interface.
【Cumulative Memory】Unlike standard testers that erase data upon disconnection, this device records the energy log from 0 to 9999Wh when the power bank shuts down. It automatically accumulates capacity upon reconnection, ideal for monitoring battery health over multiple cycles.
【Nighttime Power Off】Housed in a compact 43x25x10mm ABS casing, the screen-off function disables the display for undisturbed overnight charging. A simple press instantly wakes the tester, combining energy conservation with immediate availability.
