Excerpt: We’ve spent hours testing the YOJOCK USB C Tester, and it’s proving to be a surprisingly thorough power analysis tool. When we接入 our power banks, the multimeter’s 4-30V and 0-12A range delivered readings that aligned closely with expected capacities, making us verify charge times more accurately. The Type C voltage/current tester is handy, especially when comparing different USB cables—our results showed minor discrepancies under high loads, hinting at hidden inefficiencies. What impressed us was how itfunctionedas both a voltmeter and ammeter, even estimating battery life for devices in real-time. While it’s slightly pricier than basic testers, the detailed metrics—like power bank capacity and working time—make it a must-have for tech enthusiasts. Surprisingly accurate for daily use, we’re glad to say the YOJOCK delivers deeper specs without unnecessary frills.
