Capabilities of the YOJOCK USB C Tester
The YOJOCK KWS-2303C functions as a comprehensive diagnostic tool for USB-C ecosystems. Its primary strength lies in its support for a wide variety of fast charging protocols, including PD3.0, QC3.0, and proprietary standards like Super VOOC. Because the device is designed with a bidirectional interface, both sides of the tester can function as either an input or an output, providing flexibility when troubleshooting power banks or cable bottlenecks.
The inclusion of a curve monitoring function allows users to visualize voltage and current fluctuations over set intervals, ranging from five minutes to two hours. This is useful for identifying intermittent power delivery issues or confirming the stability of a power supply under load. Additionally, the power-off storage ensures that capacity measurements are not lost, which is essential for testing the true output capacity of portable batteries.
From a physical construction perspective, the unit uses a 12A high-current terminal to maintain stability during heavy testing loads. While the interface is compact, the data density on the display is high, providing real-time readouts of temperature, energy, and timing alongside standard electrical metrics. Users who regularly work with high-wattage charging setups will find the 360W handling capacity sufficient for most consumer electronics.
Our Verdict
The YOJOCK 360W power meter is a highly capable, cost-effective instrument for monitoring USB-C charging hardware. It is a suitable choice for users who require precise data logging and protocol verification without a significant financial investment.
